Cozy Home Attic Insulators

When considering insulation for your home, it’s important to understand the facts about different product types and options. First things first: there is no such thing as a “best insulator.” Surprised? According to the Building Sciences Corporation (BSC), all insulation types perform equally well when properly installed and air sealed.

Insulation Materials:

Fiberglass Insulation

Mineral wool Insulation

Cellulose Insulation

Spray foam Insulation

Tips for choosing a Insulation Materials:

Fiberglass insulation—Contains 40-60% recycled content, depending on manufacturer and facility.

Slag wool and rock wool (the two types of mineral wool insulation)—contain 10-15% and 70-90% recycled content respectively.

Cellulose insulation—Has significant recycled content, with manufacturers often claiming 80% or more.

Spray foam insulation—Is strictly a chemical product and therefore contains very little recycled content.

Insulation Materials Safety: 

Fiberglass and mineral wool insulation are naturally non-combustible.

Spray foam insulation will ignite at 700°F.

Cellulose insulation—Requires approximately 20%, by weight, of fire retardants to reduce flammability.15 This adds fire-resistance, though the material itself is not non-combustible or smolder-resistant and products must carry a fire hazard warning. The Consumer Products Safety Commission requires cellulose manufacturers to warn customers that the product presents a fire hazard. The risks are real. In 2015, Allstate Insurance is suing an insulation contractor over a house fire allegedly caused by improper installation of cellulose insulation.
