The purpose of any insulating material is to prevent air and moisture intrusion by sealing gaps and cracks. As popular as it might be, traditional fiberglass and cellulose insulation does not provide an effective air seal, since air can pass right through it. By comparison, spray foam insulation (SPF) stops air from moving through vulnerable areas.
What are the benefits?
- Saves on heating and cooling costs
- Makes your home more comfortable
- Stops moisture from getting inside
- Adds strength to vulnerable areas
- Is not susceptible to mold growth (unlike traditional insulation)
- Keeps dust, pollen, and environmental allergens outside the home
- Will not sink, sag, or retain water (like traditional insulation)
- Provides a vastly superior air barrier
- Contains environmentally-friendly materials
- May increase home’s value
The numbers
In head-to-head matchups with traditional insulation systems, energy and utility savings of 30 percent and more have been reported. And even though spray foam insulation typically has higher initial installation costs than traditional fiberglass insulation, the cost can be recovered in no time because of the energy savings. In fact, SPF roof contractors report that the entire cost of the insulation system can be recovered in less than 5 years, which means it pays for itself!
