With much of the country still thawing out from a blanket of snow and several days of sub-zero temperatures, many homeowners are taking a fresh look at their home's existing insulation. If it is several years old or has become moist or compressed, its ability to stop air infiltration and keep the interior of the home comfortable in severe weather will be limited. 

Homeowners who would like to take steps now to keep their families warmer and more comfortable in the future may want to consider the use of a relatively new insulation product — foam. 

No dead air space is required

Insulating a home properly requires the use of strategic spacing to form dead air spaces between the wall, floor, and roofing surfaces and a traditional insulation product, such as fiberglass batts or rock wool. This air-filled space helps to maintain a healthy ventilation process within the structure and helps homeowners avoid rising humidity levels and drafts that could make the home feel less comfortable. 

When foam insulation is used, however, it can be sprayed directly on the wall, floor, and roof surfaces without leaving a dead air space. As the foam is sprayed on, tiny cells filled with air combine with the foam material to act as a dead air space provide a barrier against air loss. 

Awkward spaces become easier to insulate

Those who own an older home may find that the remodeling efforts of previous owners have left them with some areas that will be difficult to insulate properly with traditional insulation products. Foam insulation, however, can be applied in these small spaces with a wand-like applicator for a more precise delivery of the foam. 

Using spray foam to fill small openings in attics and crawlspaces, as well as around vents, pipes, and wires offers homeowners increased insulation value. Homeowners may also experience fewer insect issues when they use spray foam to seal these small openings in their home. 

Closed- and open-cell formulas are available

Spray foam is available in both closed- and open-cell formulas, and homeowners will need to understand the differences between the two. Open-cell spray foam is permeable to both moisture and vapor. Homeowners should only use open-cell spray foam in areas where no moisture is present and where a separate vapor barrier can be included as part of the insulation process. 

The most popular form of spray foam insulation is the closed-cell variety because it forms its own vapor barrier and will not absorb moisture or water. Homeowners who would like to learn more about foam insulation for their home should take time to discuss their needs with a reputable foam insulation contractor in their area.
