Is Spray Foam Insulation Right for Your Project?
Polyurethane spray foam falls into two categories: “open-cell” or “closed-cell”. There are pros and cons of both. AHE can determine which spray foam type would be best depending on the application. We can also help you decide if there’s a better alternative.
Spray Foam is Often More Expensive
Spray foam tends to be more expensive than other spray insulation products. It does have the advantage of being a rated vapor barrier and is commonly an efficient solution for vaulted ceilings and areas where insulation with high R-value is needed. Another common application is as attic foam.
Spray Foam is Not Environmentally Friendly
Spray foam is composed almost entirely from petroleum so we do not consider it as a “green product” like the cellulose and denim insulation we use. Bio-based spray foam insulation has been introduced as a “green” spray insulation but the actual bio-content is typically less than 10% with the remaining 90% petroleum. However, foam manufacturers claim that the embodied energy and petroleum it takes to produce is quickly made-up with the energy savings when used in the home.

Even if there is some fluffy material in your attic, there is most likely a lot of room for improvement. In fact, poor installation, even over a small area of a home, compromises the effectiveness of your attic insulation greatly. Even if your energy audit report says that you have an appropriate…
Why Does Air Sealing Have to Happen Before Insulation? →
As the home performance contracting industry moves to improve the energy efficiency, comfort, safety, and health of existing homes by applying building science principles, one of the most ubiquitous problems building analysts are finding is that, even recently…
Why Use UltraTouch Insulation? →
Most homes built before 1989 were constructed without floor insulation. “Heat rises” was the theory, so attics were insulated, then walls. In reality, while warm air does usually (but not always!) rise, heat itself does not rise – it simply moves from warm areas to cold areas.
