Basement insulation

Wisconsin winters can be brutal.

But you really want to use the space in your basement for everyday living. So you’ve decided to insulate the basement or lower level so you can expand your living area, invest in your home and create a nice warm space to retreat to in the winter as well as a cool place in the summer.

There are two places to insulate: outside the basement walls and inside the basement walls. The expert technicians at ABT are well-versed in protecting basements across northern and northeastern Wisconsin − both in the winter and during the summer. Let our professionals give you an assessment on how to insulate your basement and gain more livable square footage in your home.

Outside foundation walls

Exterior rigid foam insulation over the outer basement wall is usually applied during construction. It also can be added as part of an exterior drainage project. If you’re planning to have a particular drainage project involving your foundation outside, take the extra step and have rigid foam insulation installed around your foundation.

Inside foundation walls

ABT offers a closed cell spray foam to seal and protect basements from the weather. Our technicians can spray insulation around the rim (aka band or perimeter) joist that rests on top of your foundation. It provides another layer of protection from the weather.
