This is one of the thinnest points in a home’s exterior, which allows outside air to easily leak into the basement. This area is also a convenient way for pests to enter a home – spiders, bugs and other creatures can easily find their way from the ground outside your home, into home through penetration points left behind around HVAC, electrical and plumbing access points around the basement ceiling.
Spray foam is an ideal product to both insulate and air seal the rim joists and box sills. Spray foam insulation is a two-in-one product that both seals air leaks and insulates – and it goes beyond what a homeowner can do on their own.
Insulating and air sealing your rim joists and box sills will make your basement (and entire home) more comfortable, help keep out pests and help reduce your energy bills. Contact us to schedule your free estimate!
