We understand that consumers make decisions based on many factors, including price, performance and, in more and more cases, on the environmental impact of the product.
Comparing Insulation Types
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.
Recycled Content
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.
Fire 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.
Moisture
No insulation product alone is capable of preventing moisture-related problems in the home. Home moisture management is complex—it’s about letting moisture in, letting it out, and giving it the chance to evaporate. Installing any insulation product, in part of or all of a home, can’t magically solve or prevent moisture problems. However, moisture is an important factor to consider when installing installation in a new or existing home.
In building a new home—ask your builder about their approach to addressing moisture. The strategy should take into consideration insulation, vapor retarders, material choices in the building envelope and your local climate. In an existing home with moisture issues—hiring a specialist to diagnose and fix moisture problems is the prudent choice. The solution must consider the same factors as in new homes, though addressing the issues may be more difficult.
Mold
If you’re concerned about mold in your home, it’s important to understand the facts. Mold is a product of moisture and the presence of food (any organic material) for mold spores. Any moisture issues should be addressed immediately.
If products in the home are composed of organic material, they can be food for mold. Cellulose insulation is a possible food source if not properly treated.
Spray foam, fiberglass and mineral wool insulation are not food sources, however mold can grow on any surface when the conditions are right.
Note: Some insulation products advertise “mold resistance,” but mold growth can occur on ANY surface if there is water and food present. No product can prevent mold.
