Floor Insulation

Floors over vented crawl spaces and garages are cold in winter because there is nothing between the subfloor and the open air. Batts that sag, fall or were never installed leave the floor exposed.

We insulate floors for homes across Nashville and Middle Tennessee. We install batts held with support wire, rigid foam or spray foam against the subfloor, air-seal around ducts and plumbing and replace old fallen insulation.

FAQ

Common questions about floor insulation

Why do my batts keep falling?

Pins or wire were never used, or moisture made them heavy. We install them properly or use foam.

Can I just stuff in more insulation?

Not effectively. The insulation must touch the subfloor with no air gap.

Do floors over crawl spaces need a vapor barrier too?

Usually yes, on the ground, to control moisture under the house.
