Frequently Asked Questions About Fireproofing Your Insulation


Insulation keeps your property safe from the elements, bug infestations, and moisture and mould growth. What, on the other hand, safeguards your insulation? Here’s some information on how to fireproof your insulation and safeguard your home from fire hazards.

Is insulation fire-resistant?

Insulation flame resistance is determined by the material used. Mineral wool and fiberglass insulation, for example, are non-combustible. When covered with kraft paper or a foil facing, the latter, on the other hand, becomes a fire hazard. A heat barrier must be installed in this scenario to eliminate the risk.

Despite the fact that cellulose insulation is made up of around 80% recycled paper fiber, which is very combustible, it is treated with fire-retardant chemicals before being installed. Spray foam insulation, on the other hand, ignites at 700 degrees Fahrenheit. The legislation demands that spray foam insulation be covered by a thermal barrier since it is within the temperature range of a building fire.

What is the definition of a thermal barrier?

The most typical use of a thermal barrier for spray foam insulation, also known as polyurethane foam, is as a fire-resistant precaution.

A thermal barrier protects your property by reducing the vulnerability of flammable spray foam to fire. In the event of a fire, a structural barrier, such as drywall, slows the temperature rise of the insulation. It also stops the flames from coming into touch with the spray foam, or at least delays it.

What is the purpose of fireproofing paint?

A fireproof paint, such as the DC315 paint used by the contractors at Eco Spray Insulation, is an alternative thermal barrier. When exposed to fire, the paint expands to protect the insulation beneath it. This layer also works as an ignition barrier, preventing fires from spreading through spray foam insulation. Only crawl spaces, attics, and exposed open wall sections that aren’t accessible can utilize this product.

Is it possible for smoke to harm insulation?

Even if your insulation survives a fire, you’ll almost definitely have to remove it and replace it. Because insulation cannot be cleaned, smoke odours will continue to pervade your home unless the substance is removed.

Is it necessary to finish the roof before applying fireproofing?

Yes, as long as you follow the manufacturer’s directions.

Can air conditioning ducts be installed before the fireproofing is sprayed?

No. This can make access to steel beams and decking difficult. If the fireproofing is not sprayed directly on the steel, adhesion and cohesiveness may be compromised.

When the fireproofing material is applied, how long does it take for it to dry?

The material might take anywhere from 14 to 28 days to dry, depending on thickness and weather circumstances. When sprayed in confined places, proper ventilation is critical.

How can I figure out how thick something is?

The thickness is determined by the following factors: 

  •  the application space 
  •  the kind of deck and depth of the metal deck 
  •  the type of topping on the deck 
  •  the size of the supporting beams 
  •  the type of column and its size
