Why Spray Foam Insulation?

Unlike fiberglass and cellulose, spray foam insulation is an "air barrier". Reducing air infiltration is the key component to increased energy efficiency and improved indoor air quality. The air-seal results in increased energy efficiency (as much as 50%), which translates into short- and long-term savings such as the use of a properly sized HVAC unit; elimination of building wrap, less use of natural resources and lower utility bills.

The following statement is from the Energy Star government website:

Tighter home construction can offer you:

  • Improved Comfort — reduces drafts, noise, and moisture.
  • Improved Indoor Air Quality — keeps dust, pollen, car exhaust, and insects out of the home.
  • Lower Costs — reduces escape of conditioned air.

Unfortunately, there are hundreds of penetrations through a typical home's exterior. These gaps and holes are often incurred during framing, and from penetrations for wiring, plumbing, and ducts. Air sealing the house's envelope combined with proper ventilation, can reduce your energy bills and eliminate unwanted drafts and pollutants.

Reduced air infiltration combined with proper ventilation can not only reduce your energy bills but it can also improve the quality of your indoor air. Outdoor air that leaks indoor makes it difficult to maintain comfort and energy efficiency. In addition, air leakage accounts for 25–40% of the energy used for heating and cooling in a typical home.

Spray foam insulation is environmentally-safe, non-toxic and can completely air-seal residential and commercial buildings such as homes, schools, offices and more. Combined with a proper air management system (HVAC), these products are the answer to improved indoor air quality, energy efficiency and sound abatement.

Spray foam insulation offers no food value, so it cannot support bacteria or fungal growth. The effective air-sealing characteristic prevents the movement of hot air to the cold parts of the walls, preventing condensation from taking place within the wall cavities. The elimination of condensation within the wall assemblies prevents the growth of molds and mildew.

Noise pollution is reduced because airborne noise can no longer seep through walls. Areas where the difference will quickly be appreciated include offices, classrooms, master bedrooms, laundry rooms, media rooms and plumbing runs.
