Stopping Drafts

Up to 40% of energy lost by a home happens through uncontrolled air leakage. Air leaks are a big energy waster and can lead to comfort, moisture and air quality issues.

Whats the Problem?
  • Without alot of extra labor its hard to stop all air leaks with conventional insulation and materials, especially in hard to insulate areas.
  •  Over time conventional insulation can sag or settle, leaving gaps and decreasing R-value
  • When outdoor air leaks into a home, the furnace or air conditioner must work harder to maintain the desired indoor temperature, wasting energy and money
What can you do?
  • Use weather stripping, plastic window film, caulking, foam in a can (choose the right one for each application) and electric outlet insulators to help control some of the most obvious leaks at minimal cost
  • Consider a soft-spray foam insulation/ air barrier system as a whole home solution to air leaks, especially for new homes and renovations, whick can deliver up to 50% in energy savings

We have a ceramic floor above the garage and in the winter, the floor would often be 18 degrees colder than the room temperature. After removing the fiberglass and adding Icynene, the temperature difference is now less than 2 degrees, and we no longer have frozen pipes.
