Many people do not realize that eliminating air leakage is important to achieve energy efficiency, while eliminating condensation thus preventing mold, mildew, and moisture in the building.
How spray foam can improve your home
- Prevent Ice Dams
- Stop Drafts
- Prevent Mold & Mildew
- Increase structural support
Where to Retrofit?
- Attics
- Crawlspace(s) or Basement
- Rim Joists
- Exterior walls
Moisture Flow
Water vapor usually moves from areas of high vapor pressure to areas of lower vapor pressure (Hot -> Cold). The difference in vapor pressure from inside to outside, often causes the air to pass through the walls of a building. By using spray foam as a vapor barrier this moisture flow is controlled.
R-Value
R-Value is the measure of resistance to heat flow. Each brand and type of spray foam offer a different R-Value, and are published by the company in the ESR/Code Compliance Reports.
| Building Material | R-Value Per Inch |
| Steel | 0.004 |
| Concrete | 0.1 |
| Wood | 1.0 |
| OC Average | 4 |
| CC Average | 7 |
Heat loss is an important factor to keep in mind, as a product with a high R-Value may not provide a continuous seal like spray foam does.
