Why Closed cell?

Closed cell spray foam insulation does not absorb moisture. Period. Open cell spray foam insulation absorbs moisture but then dissipates the moisture within a relatively short period of time. This is unlike cellulose or fiberglass, which are porous and will allow moisture to pass right through the insulation, soaking the insulation and ruining its insulating power in the process.

Most moisture problems in houses result from air infiltration through walls and ceilings. Spray foam insulation expands to fill even the smallest cracks and openings in walls and roof sheathings, so these moisture sources are virtually eliminated. Proper construction materials and techniques usually prevent moisture buildup from other sources. Contact us if you have questions about an application with unique moisture characteristics, such as an indoor swimming pool room or a walk-in freezer.

Will foam void my roof warranty?
No, this is another myth. The suggestion here is that your roof sheathing and shingles will not last as long because the spray foam insulation increases the roof surface temperature, by preventing heat from radiating into the attic. While your roof surface temperature may be a bit higher, research shows that the temperature increase is only two to three degrees. For a Gulf coast roof surface that can reach 160 degrees or more during the summer, this is a difference of less than two percent. By comparison, the roof temperature increase just from installing dark colored roof shingles is three times greater.

Is it true that no contractor's license is required to install insulation?
Unfortunately, this is true. And it’s too bad because incorrectly installed insulation can rob you of valuable energy savings and, in the case of fiberglass and cellulose, create conditions for mold, mildew and unhealthy air quality. In addition to having independently verified knowledge and experience, state-licensed contractors are required to meet a variety of financial and continuing education requirements.
