Without proper air sealing, a building can lose a great deal of its efficiency through air leakage. It's one of the primary causes of hot and cold spots in homes which can cause discomfort for occupants. But as with any building product, insulation is only as effective as its installation, or how it's applied. Foam insulation expands to fill around every gap and void and seals against air infiltration, which is the primary source of energy loss. Indoor temperatures stay constant, allowing decreased use of heat or air conditioning. This translates into savings, both on utility bills and by extending the life of your heating and cooling equipment.

The application of spray foam actually strengthens a building's structure. The expanding foam fills the gaps between each wall, floor or roof cavity. The studs, joists, and sheeting are bonded together creating optimum structural strength. After curing, spray foam is durable and will not shrink, settle or disintegrate over time.

It is now well established and accepted by most architects and builders that controlling air infiltration is the best and most cost-effective means of reducing wasteful heat loss and providing a comfortable indoor environment. Also, since spray foam expands into the smallest cracks and holes, it has been proven to reduce the entry of unwanted pests and insects. Spray foam is a polyurethane product and does not act as a nesting ground or source of food for pests.

Flagel Insulation can install a "hybrid system" which uses first spray foam and then spray cellulose. This is a smart solution for those concerned about the "best" way to achieve energy efficiency. With this method you get optimum blockage of air infiltration and better sound control at the best price.
