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 had our barn insulated with Icynene and we had a special visit from the local gas utility because the fuel consumption was so low!
