Spray foam insulation scares homeowners more than it should, and the reason is not because it’s unreliable or expensive. The truth is that spray foam insulation can be incredibly effective, especially when it’s professionally installed.
Unlike fiberglass or cellulose, spray foam is a polyurethane-based product that expands and fills gaps, cracks and holes in walls, ceilings and other surfaces. It also serves as an air barrier and moisture vapor retarder. Because of this, it can dramatically boost a home’s energy efficiency and comfort while significantly cutting heating and cooling costs.
The Role of Spray Foam Insulation in Achieving a Healthy Indoor Air Environment
Spray insulation is also a better environmental choice than older types of thermal products, because it contains fewer VOCs and doesn’t allow the growth of fungus or mold. This is important because mold can cause serious indoor air quality problems and lead to a variety of health issues, including a general decrease in indoor air quality that may be difficult to detect.
Spray foam also has a smaller carbon footprint than other products because it uses a new blowing agent technology that isn’t based on Chlorofluorocarbons (CFC) or Hydrochlorofluorocarbons (HCFC), both of which are being phased out by international and national regulations. This is because spray foam uses the third generation blowing agent technology, which is a mix of Hydrofluorocarbons and Isobutane. This mix has a lower environmental impact than HFC and CFC, which are a mixture of methyl chloride, a potent neurotoxin and greenhouse gas.
