Many homeowners choose spray foam insulation for their homes to reduce energy bills. This premium product seals the building envelope, so air doesn’t leak into and out of the home and keeps indoor temperatures more stable, saving money year-round on heating and cooling costs. Besides lowering the monthly utility bills, spray foam also helps prevent mold and mildew and provides excellent soundproofing.
Does spray foam insulate heat?
The chemical reaction of two different composite materials, polyurethane and isocyanate, is what makes spray foam work. When sprayed, these chemicals expand and harden to fill every nook and cranny to create an effective insulating air barrier. During installation, contractors use a special spray gun to apply the material to the desired areas in a house. This link : armorinsulations.com
Before applying the spray foam, contractors must protect themselves from exposure to isocyanates by wearing a respirator and face mask. The fumes are intense and can irritate the eyes, gastrointestinal tract and respiratory system. Repeated overexposure can lead to a chemical sensitization, which means even the smallest amounts of the compound can trigger asthma attacks.
The good news is that there are new eco-friendly spray foam products with soybeans instead of petroleum. These products have a lower Global Warming Potential (GWP) rating and are more sustainable than traditional products. Additionally, some spray foam contractors are using hydrofluoroolefin blowing agents that are free of CFCs, HCFCs and HFCs. It’s important to discuss these options with your contractor before starting a project. In addition to reducing the environmental impact, these products are much more affordable than the conventional fiberglass batts that are currently being used.
