At Home Environment Solutions we consider air sealing to be a process that is just as important as the insulation itself. Air sealing can drastically improve the energy performance of an older home. We can locate ever the smallest of air leaks using are blower door test.
Air Sealing in the attic is generally a challenging project, but the benefits can be substantial. Air sealing is the technique of plugging your attics air leaks. Using spray foam and other techniques we seal all the air leaks up before blowing in the insulation. Air sealing in the attic is just as important as the insulation itself.
Recessed lighting, like any other opening in the ceiling, is a potential site for energy loss. Not only do recessed can lights leak air, but warm light bulbs also make the situation worse turning the holes into small chimneys. The heat source accelerates the stack effect, speeding up the flow of air through the light and into your attic - air you paid to heat! That is exactly what was occurring in this Bradford Woods home.
The cans recessed into the attic are large and take up a lot of space, space that for safety reasons insulation can't be blown right up against them.
Home Environment Solutions has a solution for this problem. We use TiteShell Can Light Covers to stop airflow and energy loss through the fixture. It also allows insulation to be blown right up against the covers, creating a air tight seal, which stops the flow of air back into your attic.
