Leaving recessed can lights completely exposed allows for significant air flow between the attic and the room below.
Sealing around the light with our expanding foam is a safe, effective way to eliminate this air flow.
There were gaps and cracks between every floor board.
We used an expanding foam to seal the areas and prevent air transfer.
Small air leaks into uninsulated attic space are a major source of heat loss.
Once all the gaps are sealed up the home will be a much more efficient and comfortable.
Gaps and cracks in the attic are an unavoidable part of homeownership. There are several reasons why these spaces form, but every home is subject to the airflow that can occur through these areas. This homeowner in Manchester Township, NJ had several gaps throughout his attic that was causing severe air leakage.
