Using spray foam insulation to seal holes, gaps and cracks can prevent energy loss. A tiny investment could yield big savings.
Look at areas where different materials meet.
Check between brick and wood siding, between foundation and walls, and between the chimney and siding. Also look in the basement and crawlspace, attic and the interior and exterior of your home for gaps and cracks where air may be escaping. Here are some key areas to examine:
Carefully read the instructions on the can label before use.
To help keep air from escaping through the attic, seal the gap between the attic hatch door frame and the ceiling joists.
There's often a gap in a basement where the pressure-treated wood-sill plate rests on top of the concrete foundation. In an unfinished basement, these gaps will be evident. In a finished basement with a dropped ceiling, the ceiling tiles will need to be removed to access the sill plate and the foundation.
Plumbing pipe penetrations may allow bugs and unwanted air into the living space.
Holes may be hiding under electrical outlet covers.
Window and Door Framing
Installing new windows and doors can significantly improve a home’s energy efficiency. During installation, make sure to fill the gaps around the window or door frame and the rough opening.
