When you place insulation in an existing closed wall or attic, you will most likely be using a loose-fill product known as blow-in cellulose insulation. In an attic, this sort of insulation is simply one of several options, including fiberglass batts and blown in fiberglass. When it comes to enclosed walls, however, the most practical and cost-effective solution is to blow in loose-fill cellulose insulation.
What Is Loose-Fill Cellulose Insulation?
Cellulose insulation is thick, dense, and clumpy, similar to down feathers. The primary benefit of this shape and size is that the insulation may fit in enclosed locations (such as walls) and conform around barriers like wires and ducts (found both in walls and in attics).
Technically, cellulose insulation can be made from any cellular plant material, such as corn cobs or sisal. Commercial cellulose insulations, on the other hand, are typically made from wood, and more precisely from paper recycled newspapers, cardboard, office paper, and other common waste paper products. As a result, cellulose insulation is regarded as an eco-friendly building material.
Cellulose Insulation Cost
Blown-in cellulose is more expensive than fiberglass, often costing roughly $1.20 per square foot. The cost of cellulose insulation per bag is normally between $30 and $40. It is constructed with recycled materials such as newspaper and cardboard.
The higher the R-value, the higher the cost of each project. Cellulose insulation is available in damp-spray and dense-pack varieties.
| Material | Cost per Square Foot | Project Sustainability |
| Wet-Spray Cellulose | $0.60 – $1.80 | New construction |
| Dense-Pack Cellulose | $2.00 – $2.30 | Remodeling |
Price of Wet Blown-In Cellulose Insulation
Installing damp-spray insulation costs between $0.60 and $1.80 per square foot. For new projects, wet installations work best.
Benefits:
- Fire retardant treatment
- It is less expensive than dense packing.
Drawbacks:
- It takes longer to dry.
- Can settle and leave voids
- Professional installation is usually required.
Insulating Capacity and R-Value
The R-value of blown insulation is determined by the material’s density and insulating properties. The higher the R-value, the better the material’s insulating properties. The Department of Energy recommends the following insulation levels:
- R-13 to R-30 (Floors and Crawl Spaces)
- R-13 to R-23 for the walls
- R-30 to R-60 for ceilings and attics
The attic loses about one-quarter of a home’s heat. As a result, the densest blown-in insulation in Pickering should be used in this area of the home. In older structures, additional blown-in insulation in the walls enhances insulation and can act as a fire retardant.
Why Choose Eco Spray Insulation?
A professional installation far outperforms a do-it-yourself installation. We install chemical-free, safe products made in Canada. Our installation services are also fully guaranteed.
Eco Spray specializes in blown-in cellulose insulation and offers a wide range of services such as attic ventilation, insulation removal, and insulation enhancements. We don’t skimp on quality or cut corners.
It may appear that having professionals install blown-in cellulose is a simple procedure, and it often is. Many obvious and subtle elements, such as heat transfer via walls, lighting kinds in the attic space, whether or not the chimney is properly insulated (if it flows through the attic), and many others, may go overlooked by the layperson.
The most basic part is the installation. If you want to get the most energy efficiency and lifespan out of your insulation, an expert’s breadth of expertise, experience, and equipment are important.
We’ll make sure the installation is done correctly from the start so you can start saving money on energy as soon as possible. For further information, please contact us at (416) 860-6664 or [email protected].
