Attic

What’s hotter than the outdoors on a sunny summer day? Your attic. Keep the heat out of your living space with sealant around:

Plumbing stacks and shafts
Attic perimeter
Top plates
Gas lines

HVAC penetrations
Electrical and cable lines
TV connections
Look for dirty insulation, which can indicate air infiltration

It’s where you eat, sleep and hang out, so don’t neglect the most important place in your home. Enhance your living space comfort by sealing:

Under baseboards

Window and door frames
Around perimeter of electrical outlets (not inside box)

Plumbing penetrations
Around the perimeter of covered wire and electrical conduit penetrations on exterior walls
