Knee Wall Insulation

Knee walls are the short vertical walls where a sloped ceiling meets the floor, with attic space behind. They are often uninsulated or poorly fitted, and the floor behind them may be bare. Heat flows through them and the rooms never feel right.

We insulate knee walls and the spaces behind them across Nashville and Middle Tennessee. We seal the wall, insulate it and the floor behind it, add baffles and seal and insulate the access doors.

FAQ

Common questions about knee wall insulation

Do I need to insulate both the wall and the floor behind it?

Usually, yes. One without the other leaves a path for heat.

Are access doors a problem?

Yes. A thin, gapped door can undo the work, so we insulate and weatherstrip it.

Is it hard to reach?

These spaces are tight, which is why many are left bare. Our crews work in them every day.
