  • Spreading of mold, moisture, and allergens
  • Additional wear on your heating, ventilation and air conditioning equipment

The vast majority of homes in the United States are wasting significant amounts of energy due to air leaks in their structures that insulation alone does not prevent. Following the guidelines of The Building Performance Institute (BPI), Green Energy Improvement never installs insulation without first sealing air leaks. Without being sealed, the leaks will continue to cause drafts and be more difficult to repair under added insulation. These leaks include holes and cracks in the attic and basement around electrical boxes and conduit, plumbing pipes, cable wires, dryer vents, exhaust fans, attic hatches and sill plates, as well as around window and door frames and in crawl spaces.

Sealing air leaks with spray foam greatly increases the overall R-Value (effectiveness level) of other insulating products.
Properly air sealed and insulated, your home will be more comfortable, healthy, affordable and energy efficient.
