Eco Spray Insulation has prepared this article to discuss the value of basement insulation R value and point out the key benefits it provides for summer comfort.

What is the Basement Insulation R Value? 

The R-value of basement insulation is a measurement of the level of heat resistance that home insulation offers in the basement space. The effectiveness of an insulating material’s ability to block the transfer of heat is measured using the R-value rating system. A higher R-value in the context of basement insulation implies better insulation performance since it represents more resistance to heat transfer. 

You can improve the basement insulation’s capacity to maintain a constant temperature, lessen heat gain or loss, and enhance overall energy efficiency by raising the R-value of the insulation. In order to achieve the best insulation performance and summer comfort, it is crucial to take into account the recommended R-value for your particular region and location.

Based on variables including climate and location, different basement insulation R-values are suggested in the summer. Higher R-values are typically recommended because they provide superior house insulation performance and more effectively resist heat transfer. A greater R-value reduces heat adoption from the surrounding soil, preserving a comfortable environment in hot conditions. 

As a result, cooling systems work less hard, resulting in energy savings and increased comfort. A calmer environment is also made possible by soundproofing insulation, which lowers humidity and prevents moisture problems. The best basement insulation R value for your region can be found by consulting Eco Spray Insulation contractors or local authorities, which will also provide effective summer comfort.

What are the main Benefits Canadian homeowners gain because of Basement Insulation R Value?

By having the best basement insulation R value, Canadian homeowners can enjoy a number of important advantages. Here are the top three benefits:

• Enhanced Energy Efficiency →  Canadian homeowners can dramatically increase their homes’ energy efficiency by installing an increased basement insulation R value. In the winter, basement insulation with a greater R-value prevents heat from escaping, keeping the interior warmer and lowering the need for heating systems. As a result, there is a long-term cost savings due to lower energy use and utility bills.
• Increased Comfort & Temperature Control →  Homeowners enjoy greater comfort all year long with adequate basement insulation R value. As a barrier, the basement insulation reduces heat transfer from the basement to the rest of the house. As a result, indoor temperatures are kept more consistently and comfortably, enabling a nice living environment even during the severe Canadian winters or steamy summers.
• Controlling Moisture & Preventing Problems →  A high basement insulation  R value system is ideal for preventing moisture-related issues. By assisting in the formation of a moisture barrier, it lowers the likelihood of condensation and dampness. This is crucial in Canadian regions where significant temperature swings can cause moisture to accumulate. For homeowners and their families to live in a healthy environment, effective insulation helps guard against mold spores, structural damage, and the health hazards related to these things.

Canadian households can benefit from enhanced energy efficiency, improved comfort, and efficient moisture control by investing in a suitable basement insulation R value. All of these advantages result in a home that is more livable, cozy, and healthy all year long.

Why Invest in High Basement Insulation R Value? 

Do not forget that for a comfortable summer, your basement insulation must be enhanced. Never undervalue the positive effects it can have on your general well-being and energy savings. It’s important to think about expert installation and consulting even if DIY initiatives can be appealing.

Professional insulators have the knowledge and skills to guarantee that basement insulation R value is achieved. They are able to evaluate your particular requirements, make recommendations about the best insulation materials, and efficiently implement the insulation system.

Investing in professional insulation installation and advice not only guarantees that the insulation is completed correctly but also enhances the advantages you’ll enjoy in terms of energy effectiveness, convenience, and cost savings. 

To ensure that your summer comfort is a top concern, take the initiative and get in touch with Eco Spray Insulation reliable insulation project manager who is always willing to help you with every insulation detail related to your basement insulation R value project and provide you with a free on-site assessment as well. 

By insulating basement walls you will contribute to both moisture and mold growth prevention as well as keep pests out of your home. This article, provided by Eco Spray Insulation, offers a wealth of information on the insulation of basement walls, including its benefits and various insulation options that you may wish to consider before embarking on your basement insulation project.

Why Insulating Basement is worthy of your property? 

Basement insulation, as a wise home investment, is worth considering for a number of reasons including increased home comfort, energy savings, indoor quality, home value and reduced noise levels. By making your home more energy-efficient and comfortable, basement insulation can enhance your quality of life and save you money on energy costs.

You may make your basement a comfortable location by hiring a local insulation contractor to insulate the space underneath your home. The main benefit of insulating basement walls is to stop heat from transferring between the outside surfaces of your house, such as the foundation. After being air sealed and insulated, your basement will be protected from Canada’s harsh winters and exhausting, hot summers. Your home will have more consistent temperatures throughout if the basement is better temperature-controlled.

Why Spring is the Perfect Season for Insulating Basement Walls?

Several factors make spring the ideal time to insulate basement walls:

• Temperature Stability →  Since temperatures during the spring are frequently mild and steady, installing basement insulation is made easier because there is less risk of extremely hot or cold weather.
• Increased Energy Efficiency → Insulating basement in the spring will help you get your house ready for the hot summer months by reducing the need for air conditioning, which will result in cheaper energy bills.
• Reduced Moisture Levels →  Since springtime humidity levels are often lower than those of summer or fall, now is the perfect time to install basement insulation to stop moisture from entering and lower the chance of mold growth.
• Shorter Installation Periods → Since foam contractors are often less busy in the spring, scheduling the installation of your house insulation may be simpler and quicker.

• Comfortable Indoor Atmosphere All Year Long → By insulating basement walls in the spring, you can improve your home’s year-round comfort by helping to maintain constant temperatures and reducing drafts.

By taking advantage of spring’s advantages, you may get your house ready for the warmer weather and enjoy a more cozy and energy-efficient living environment.

Which is the Best Home Insulation Option for Insulating Basement Walls?

For insulating basement walls, spray foam insulation is a high-performance insulation solution that provides a great number of advantages. 

Both open cell and closed cell spray foam are available options that can be applied to basement walls. Open cell spray foam for regions above ground and closed cells for portions below ground is a common recommendation from Eco Spray Insulation foam contractors. 

Closed cell spray foam is a perfect vapor barrier that keeps moisture from passing through it, but it can also conceal leaks that could cause mold. Furthermore, open cell spray foam won’t hold water, and leaks will be obvious.

• Premium Insulation Performance →  Spray foam insulation has a greater R-value per inch than other types of insulation, which makes it more efficient at preventing energy transfer through your walls. R-value is a measure of insulation’s capacity to resist heat flow.
• Air Sealing Capabilities →  Spray foam insulation swells to fill in voids and crevices in your walls, forming a smooth air barrier that aids in stopping air leaks and moisture intrusion.
• Moisture Resistance → Spray foam is a moisture-resistant insulation material and can help stop the formation of mold and mildew in your basement, improving indoor air quality.
• Durability → Spray foam insulation, when incorrectly installed, can endure for many years before needing to be updated, offering a powerful and durable home insulation alternative.
• Versatility →  Spray foam is a versatile and efficient option for insulating the whole basement because it can be utilized in a range of applications, such as walls, ceilings, and floors.

Why Basement Insulation Maintenance and Upkeep is important during Springtime?

As mentioned before, basement insulation is extremely beneficial for any property type. Home insulation should be correctly installed in your home’s basement by the right professionals who have significant knowledge and experience in insulating basement walls, ceilings, foundations, etc. 

• Ensure Insulation Performance → Basement insulation can become damaged or compacted over time, which reduces its ability to stop heat transfer through your walls. Regular insulation inspections and upkeep can assist find any problems and fix them before they affect the function of your home insulation.
• Keeping Moisture Out →  Insulation that gets wet or damp loses its insulation capabilities and turns into a haven for mold and mildew. Your basement walls can stay dry and avoid moisture infiltration with routine cleaning and upkeep.
• Maintaining Indoor Air Quality → Deteriorating or broken basement insulation may release hazardous particles into the air, lowering the quality of your indoor air. Your home insulation can remain intact and contamination-free with regular maintenance.
• Preventing Structural Damage →  Your basement walls and foundation can sustain structural damage from moisture infiltration and mold growth, which will require expensive repairs in the future. These problems can be avoided with routine maintenance, which will also protect your home’s structural integrity.

Consider insulating basement walls this spring if you want to increase the comfort of your home and increase its energy efficiency and indoor air quality. To get started, get in touch with the Eco Spray Insulation project manager and take a free project estimation on your upcoming home improvement project on insulating basement walls. 

What is R-Value? 

The R-Value measures the capability of an insulation system to keep a building compact and block heat flow. The higher the R-Value, the greater the insulating effectiveness power and resistance to heat flow.  In other words, the material with a high R-Value is a better insulator than the material with a lower value. The amount of insulation needed depends on the type of insulation you are using, climate, type of heating, the R-Value you want to achieve, and the size of the space you are insulating. R-Value is not the only thing you need to consider when choosing the insulation you use in your house. Airtightness is also important because air leakage accounts for 40 percent of a home’s energy loss.

But a higher R-Value isn’t always required for every home because there is no “best” R-Value. The requirements for certain R-Values are within the Ontario Building Code. Based on its climate different zones require a different minimum R-Value. Properties that are located in cold climates require a minimum R-Value of 6, while properties located in warmer climates require an R-Value of 3 or 4. The one that suits your environment’s unique conditions most effectively is the best insulation R-Value.

What are Some Common R-Values?

The total R-Value of a wall or ceiling, depending on application, may need to be higher in which case, a thicker layer of insulation or a more effective type will be required. Which will lead to a higher overall R-Value within the house. The R-Value of an insulative material is measured “per inch”, which indicates the insulative material’s ability to resist heat per inch of thickness. The R-Value of a wall or ceiling measures the insulation material’s ability to resist heat flow. The highest R-Value when measured by inch spray foam has it at about 3.7-6.5 per inch, open and closed cell respectively. Blown-in fiber insulation is at about 3.5 per inch and fiberglass batts are at about 2.9 per inch.

What Does R40 Insulation Mean?

A few years ago attic blown-in insulation in Ontario was R40, and its thickness was about 10 inches of blown-in cellulose and more than 12 inches of blown-in fiberglass. But now it has changed and according to the Ontario Building Code 2020-2021 and to the professionals, the recommended R-Value for attic insulation in Ontario is between R50 and R60, 18 inches blown-in cellulose and 22 inches blown-in fiberglass. Keep in mind that if you insulate your attic not only, you will keep indoor temperatures comfortable and consistent, but also it will create a barrier to sound.

Also, air sealing is very important because air can leave through the many leaks in the attic, or air can enter from outside and can account of heat loss. Poor attic insulation is responsible for 25 percent to 30 percent of heat loss. A higher R-Value means a better-insulated attic. If you have already insulated your attic, you can do a calculation to see the R-Value just by looking at the type of insulation:

• Rock Wool –  looks like real wool and you may find it in black, yellow, and gray color.  2.8 * Insulation depth = R-Value
• Fiberglass – looks like loose fibers with a light pink, white or yellow color. 
• 2.5 * Insulation depth = R-Value
• Cellulose – looks like small gray flat pieces of fibers.
• 3.7 * Insulation depth = R-Value

Why is Spray Foam Insulation the Best?

In comparison to other types of insulation, spray foam is more environmentally friendly. Spray foam insulation is known also as foaming insulation or sprayed insulation. This type of insulation is a two-part liquid insulation material that insulates and air seals wherever it is applied in the property. And air sealing a building helps address moisture which reduces the risk for mold and mildew growth. There are two types of spray foam, open and closed cells.

Open cell is used for interior applications such as the underside of roof decks, attics, wall cavities, basement walls, etc. Open-cell foams low-dense structure allows moisture permeability, to help contribute to moisture management, and provides sound dampening qualities. Its R-Value is 3.5 per inch.

While closed-cell insulation is used in exterior and interior applications. It is a rigid material that helps reject lots of water, adds wall racking strength as well as impact resistance. Closed-cell foam has a higher R-Value than any insulation, it ranges from 5.0 to 7.0 per inch.

Regarding the thickness of the spray foam insulation, it depends on certain factors. Ontario Building Code recommends that the insulation levels should be relative to the part of the structure being insulated and to the climate zone. It is very important to examine also the degree of moisture permeability that is needed. These are the key factors that can determine the R-Value and also which type of insulation open or closed cell should be installed.

Moisture is the key ingredient causing mold in basement areas, but there’s more than just a little moisture that can lead to a mold infestation.

1. Excess Moisture: Leaks, spills, and cracks in your foundation also can cause higher humidity and moisture. If you don’t catch and fix these issues directly, mold will begin growing. Try adding a dehumidifier in your basement to stay humidity and moisture low. Using air con during the summer months also will help decrease the humidity and stop the spread of mold.
2. Leaks in Your Roof and Walls: Water that leaks in from your roof or pipes are one of the causes of mold in basement areas. A leak brings an endless supply of water and moisture to dark areas in your home. Since most pipes and roofs have a layer of drywall and insulation around them, they create perfect places for mold to grow. Because the mold spreads, you’ll start seeing it growing on your walls and ceilings. Our experts have to fix the leaks and repair the moldy areas.
3. Flooding: Excess water in your basement and residential isn’t an honest sign. Flooding causes excess water to leak and accumulate in your basement. Not only are floors wet, but the floodwater will increase humidity making even the dry areas vulnerable to mold. If you don’t start drying the world within 24 hours, mold will start to grow. Fortunately, there are many effective cleaning methods to urge your home to dry fast. One of them is to call us so we can do a professional job.
4. Wet Clothing: Do you exercise tons or have you ever just been available from the rain? Wet clothes are another culprit of mold in basement areas. If you throw your clothes within the basement hamper while they’re wet, mold can start to grow on them. Clean clothes that are left within the washer for each day or longer causes mold to grow on the garments and therefore the washer. The mold can spread from your clothes onto the ground, and in extreme cases, onto the walls of your basement. Always open up and dry your clothes to stay both them and your home free from mold.
5. Condensation: Excess condensation causes mold around windows, doors, cold pipes, and concrete floors. When these surfaces are cold, condensation will form. You’ll find a number of these to be particularly cold during the winter months. Areas with or near condensation are prime areas for mold growth. Carpet over concrete floors can cause mold in basement areas albeit you can’t see it.
6. Poor Ventilation and HVAC: A house with poor ventilation can cause moist stagnant air to supply mold in basement areas and your ventilation. Dirty filters in your HVAC system can house mold and mildew. Moisture gets into the air from steam made by cooking, cleaning, and bathing. Fans and ventilation in your home disperse the moisture to stop mold. However, when the ventilation isn’t working, mold can grow around bathroom fans and within the vents. Putting our best effort, we will make your home a safe place to live in.

Which Part to Insulate in the Basement?

There are three major places where insulation is effective: exterior wall, interior walls, and ceilings. The simplest insulation placement depends on how the basement is employed, also it depends on if the building is already existing otherwise you are constructing a replacement building.

• Wall insulation: Wall insulation is the most significant part of the basement insulation because the utmost amount of warmth is transferred through walls, especially if your surrounding climate is colder within the winter season.
• Ceiling insulation: A general thanks to insulating the ceiling of your building’s basement is fiberglass batt insulation. it’ll make the space within the basement much warmer and thermally stable.
• Floor insulation: once we start constructing a building, we confirm that the inspiration is robust and doesn’t allow any quiet leakage within the building.

Insulating the basement with different products:

Pros of Basement Insulation

• Staying Warm. Gaps, cracks, and poorly insulated walls permit valuable warmth to flee from home. If you set insulation in your walls and ceiling in your basement, it’ll boost comfort and cut heating costs. and through the winter, uninsulated walls don’t just create uncomfortable conditions in your basement, they will also make the primary floor unpleasantly cold.
• Moisture Issues. Ground moisture can enter the house through the inspiration walls. Closed cell SPF foam sprayed onto the within of a foundation can help to stop moisture intrusion through the walls. If fiberglass is the choice for the outside wall insulation, please make sure that the vapor barrier meets local code requirements.
• Prevents Freezing of Water Pipes. In areas where the mercury drops frequently, water pipes get frozen easily within the basements. Thus, basement insulation is the best and cost-effective solution.
• Reduces Energy Consumption. When you insulate the basement, there’s no place for warmth to flee. Thus, maintains the specified temperature within the building which further hampers the energy consumption during the variable climate.

How to Insulate Basement Walls

Spray foam

Spray foam is perhaps the simplest possible insulation material for basements and damp areas. Closed cell spray foam is ideal for locking “out” the water vapour that inherently wants to migrate from your damp basement walls to your finished basement rooms. Spray foam offers several benefits including additional structural stability, great vapor barrier, easily covers pipes, wires, and other utilities and it provides exceptional R values. The issues with spray foam are its a substantial tag (although this may recover with time) and it’s a really messy task. However, if you’ll afford the value and mess then this is often the last word insulation product. We at Eco Spray Insulation, use the best of the products to make sure that we approach the clients requests.

Foam Board

The next best basement insulation method is using foam board products. This is often the tactic that we use most frequently and it’s the tactic that the majority of DIY folks can handle. It’s also quite a bit cheaper than spray foam so it’s a beautiful alternative. There are many foam board products on the market so I suggest you read Foam Board Insulation Types and R Values for a fast education on the various products available. We have the best equipment and our professional team will be there for any request or advice.

The key to using the foam board is selecting the right thickness and sealing it properly to make an efficient vapor barrier. If you’re just getting to use foam board then you’ll presumably need 2 to 4 inches in thickness counting on local energy code requirements. I like to recommend sealing all the joints with Tyvek (or similar) house wrap tape. you’ll also use “Great Stuff” spray foam during a can to seal around all of your utilities and also along the rock bottom of the froth board. For more information on using foam board, I like to recommend you read the way to Insulate Basement Walls with Polystyrene Insulation.

Hybrid Foam & Fiberglass Insulation

The last method that we have used may be a hybrid system of froth board and fiberglass. This method is the least expensive yet I think it’ll perform well in basements that don’t have visual signs of water infiltration. This method shouldn’t be used if you’ve got a history of water, even small amounts.

In this method you’ll be installing a layer of froth board, sealing it as noted above. Then you’ll frame a wall (wood or steel as I don’t believe there’s much difference) ahead of the froth board. Finally, you’ll install fiberglass insulation within the stud cavities. Again the key here is to return up with the right R Value supported local energy codes. Based on our experience you shouldn’t use a vapor barrier over the fiberglass insulation during this method.

Questions and answers

Q: What quite a drywall should I exploit on my basement walls?

A: Drywall comes in special moisture-resistant varieties, including “green board” or green drywall and purple drywall. Either is superior for basement applications to the quality white drywall. If the basement is at high risk of flooding or regular high humidity, you’ll also want to think about cementitious products like smooth panels, or maybe galvanized metal or other modernistic finish materials.

Q: What is the best way to insulate basement walls?

A: The 5 basic categories of insulation include foam board, spray poly foam (SPF) insulation, fiberglass, cellulose, rockwool. In some cases, a hybrid of systems also can be effective, like fiberglass and spray foam used together.

Q: Is it important to insulate your finished basement?

A: Yes. Insulating below grade increases comfort, and provides HVAC savings and moisture control. Homeowners can save $390 on electrical costs per annum with a finished basement. And while the return on investment does take time, insulation upgrades actually offer a quicker payback than window replacements.

Q: What exterior insulation should I exploit for my basement?

A: Ideally, exterior insulation should be installed before backfilling walls. However, if permanent features like walks, driveways or patios make excavating the basement wall too costly, then foam board should run down several feet along the foundation’s outside wall then continue horizontally out from the vertical walls for 3’ to 5’.

Conclusion

Basement insulation is unquestionably a crucial factor to think about while insulating other parts of the building and particularly if that building is your comfy house. you would possibly think that thermal insulation may be a costly approach or investment but if you’re during a construction phase then it’ll not cost you much compared to the opposite investments. It surely enhances the lifespan of the building and reduces the post-maintenance costs. Live comfortably and save your energy consumption to scale back your expenses. The key to our success is that we put the needs of the client first, give them solutions, and get the work done in a timely and very efficient manner.

Why Insulation?

The most obvious benefit of having a well insulated property is increased thermal efficiency, which is a measure of your home’s ability to maintain a desirable temperature internally. It is crucial that insulation is fitted in order to make any space more efficient at this job. Regardless of what time of the year it is, with good high quality insulation, you have the best chance of maintaining the kind of climate you want in your home.

Once you insulate your home, you will minimize the need to run your heaters and air conditioners as much as you previously did. This will help you keep more money in your pocket and less going towards your energy bills. If you decide to insulate your home during the stages of building it, you will also find that the construction phase benefits from a speedier build. This is because, as insulation covers the interior of a building under construction, internal work can proceed uninterrupted.

Another advantage of insulation is that it provides your building with some level of sound dampening. This means more quiet, inside as this extra layer of insulation material acts to further prevent external sounds from being heard inside your home and sound from your home being heard outside.

Understanding R-Values

Before choosing which type of insulation is best for your home, it is important first to understand R-Values. R-Value is a way of measuring your insulation’s ability to resist heat flow. The higher the R-Value of insulation the more effective is at insulation your property.

But remember, when selecting the appropriate R-Value for your home, it won’t always benefit you to select the highest, because of different build styles of home and different environments call for different levels of heat resistance. For example, one home may require insulation rated with an R-Value of 7, while another can have the same level of protection at an R-Value of 4. To find out what’s right for you, it’s best to have a professional insulation company to access your home.

What Type of Insulation Should I Choose?

Each type of insulation provides a unique set of benefits capable of being maximized in certain uses. Eco Spray Insulation can help you determine which type of insulation is the best fit for your needs. We have listed below a brief introduction of each type:

Spray Foam Insulation

Spray foam insulation can be used in nearly every part of a home including, wall cavities, joists, attic and basements. It is an effective product with an extremely high R-Value for every inch that is applied. Spray foam is available in both open and closed cell variations and it offers an air and vapor barrier in addition to its insulative qualities.

It is quick and easy to install and doesn’t require any additional upkeep or installation materials, like an air barrier. At Eco Spray, we work with spray foam insulation because it offers exceptional value in terms of both indoor and your return on investment.

Fiberglass Batt Insulation

An effective and affordable option for homeowners looking to make upgrades, fiberglass batt insulation is a common choice for wall insulation. It is made using recycled materials, fiberglass batt can greatly improve a home’s energy performance when professionally installed. They are flame retardant and can be installed in attics, wall cavities and other areas of the home.  

Batt style insulations do really well at retaining their R-Value over time, this is why they are so commonly used. They are very inexpensive and easy to install and don’t sink or settle after installation.

Blown-in Insulation or Loose Fill Insulation

Blown-in or loose fill insulation is rapidly becoming a favorite type of insulation because of its ease of installation. Blown-in is made up of small chunks of either cellulose or glass fibers. It is usually used in attics and to fill wall cavities. A small opening is all that is needed to fill a space, no walls need to come down.

Blown-in insulation is a great option for irregular spaces where a fast installation might be preferable. So if you are interested in environmentally friendly options, a cellulose based blown-in insulation might be a good option, since it is made of post-consumer paper waste.

Choosing the Right Type of Insulation

When selecting the perfect insulation for you, it comes down to a variety of factors, including climate, your home type, and budget. But if you are looking for the best long-term solution, foam insulation products will create the air seal in your home that will make it more comfortable, while saving money on your monthly energy bills. Foam insulation doesn’t settle and it fills all the crannies and nooks where it is installed.

Walls

Basement walls are the best thing to insulate in a home. It should be insulated with non-water sensitive insulation that prevents interior air from contacting cold basement surfaces. Allowing interior air (that is usually full of moisture, especially in the summer) to touch cold surfaces will lead to condensation and mold.  

Floors

Basement floor slabs are best insulated underneath with rigid insulation: both extruded or expanded polystyrene are a success. Although the energy savings of sub-slab insulation are not as significant as basement wall insulation, it does have a significant improvement in comfort and moisture damage resistance.

Ceiling

Basically, you have two options: insulate your basement ceiling or insulate your basement walls.

Insulating your basement ceiling means the warm air from your interior floors to the basement is slowed down, lowering the temperature and raising your chances of moisture problems or frozen pipes in the winter. You also don’t save nearly as much money on your energy bill as you hope.

The right material for basement insulation.

Rigid foam insulation consists of boards made of solid foam insulation and covered on one side with a radiant barrier. Rigid foam boards are attached to basement walls to seal and insulate the space. By insulating basement walls instead of the basement ceiling, the basement space is brought inside the home’s building envelope. The basement becomes part of the building’s conditioned space, which means that it will be more comfortable. Basement wall insulation also protects hot water lines and HVAC ductwork in the basement from cold winter temperatures that compromise the performance of your hot water and heating systems.

Rigid foam is ideal for the basement environment because of its water resistance and durability. Rigid foam won’t be damaged by leaks or mold, ensuring you have a long lasting solution for your home.

How to Insulate Your Basement?

Step-by-Step Basement Insulation Installation

1. After the cement is set, apply a foam board adhesive to the rear of a polystyrene insulation panel. Then the second step is to press the panel to the wall.
2. Next, you should create a wood grid that will hold the drywall in the basement. 
3. The third step is to use a hammer drill and a 3/16-inch masonry bit, drill 5-inch holes through the 1×3 and into the concrete wall. This acts like a spring that tends to straighten out and anchor the spike into the concrete wall.
4. Once you have set the horizontal boards, screw vertical 1x3s to the horizontal 1x3s with 1 ⅝-inch drywall screws. This will create a vertical and horizontal gap for any future electrical wiring to be installed. Space the horizontal 1x3s 16 inches on center, and finish installing the vertical boards.
5. After all these steps your grid is in place, you can install your drywall. For basements, a moisture-resistant green board is best.

Insulate inside or outside?

Insulating on the outside is best, but it is often necessary to insulate from the inside for economical and practical reasons. Sometimes a combination of approaches is required. Examine the advantages of each approach carefully.

Insulating inside

This method will depend on a number of factors, including whether there are moisture issues, the need to account for moisture and air/vapour barriers, how you plan to use the space, and, finally, cost.

Advantages of inside insulation

• It can be incorporated into a plan to finish the basement.
• The work can be done at any time of the year and can be done one section at a time. Often all or part can be a do-it-yourself job.
• It is often easier and cheaper to insulate the full wall and achieve high insulating values.
• The landscaping and driveway will not be disturbed.

Disadvantages of inside insulation

• Do not insulate a basement with moisture problems from the inside but if you have to, before taking measures to eliminate the moisture before adding insulation or your new walls will rot.
• Adding insulation to the inside will make the foundation walls even colder. This means air humidity will get in contact with the walls and lead to mold. 
• Obstructions such as electrical panels, wiring, plumbing, stairs, and partition walls make the work more difficult and the insulation and air barrier less effective. 

Insulating outside

This involves excavating around the foundation, waterproofing, and installing insulation. 

Advantages of outside insulation

• The outside wall tends to be more continuous and easier to insulate.
• You can effectively see and correct any moisture or structural problems (efflorescence, cracks, spalling and eroded mortar). 
• There is no disruption in the house, no interior work, and no inside space lost.
• Freeze-thaw stresses are eliminated, and frost is unlikely to penetrate down to the footings.
• The mass of the foundation is within the insulated portion of the house and will tend to even out temperature fluctuations.

Disadvantages of outside insulation

• Digging a trench around the house by hand can be difficult and risky.
• Storing the dirt can be a problem.
• Excavation cannot be done in winter and can be a problem in the spring.
• Features such as non-removable steps, paved carports, shrubbery, trees or fences can make the work difficult.
• Rubble or brick foundations could be partially supported by the soil.
• It is expensive to obtain high insulation levels, and the retrofit may detract from the appearance of the house.

Why is the insulation of the basement important?

If you insulate your basement in a proper way, it can save you money on heating and have a very comfortable living space. In a lot of cases, a basement with insulation installed on its exterior walls it’s considered a conditioned space. The basement is more connected to other living spaces than to the outside, which makes basement wall insulation preferable to ceiling insulation.

In new construction, adding insulation on the exterior of the basement walls will do the following:

• Minimize thermal bridging and reduce heat loss through the foundation
• Protect the damp-proof coating from damage during backfilling
• Provide some protection against moisture intrusion
• Make the foundation part of the thermal mass of the conditioned space, thereby reducing interior temperature swings
• Reduce the potential for condensation on surfaces in the basement
• Conserve room area, relative to installing insulation on the interior.

In an existing home, adding insulation to the exterior of the basement walls is impractical. Interior basement wall insulation has the following advantages:
