Furring Strips
Definition and meaning of Furring Strips in real estate.
Furring strips are thin strips of wood or metal used to level uneven surfaces, create air barriers, or provide a secure backing for finishing materials on walls, ceilings, and floors. They are commonly applied over masonry or concrete walls in basements to allow for the installation of drywall.
In more detail
In construction, these strips are attached directly to the existing structural surfaces to create a flat plane. They also establish a small gap between the masonry wall and the new drywall, which helps prevent moisture from transferring into the living space. Builders often use furring strips when remodeling older homes that have irregular framing or uneven joists.
By creating a level grid, they ensure that the final wall or ceiling appearance is straight and uniform.

Frequently asked questions
Do furring strips provide insulation?
While the strips themselves do not insulate, the gap they create can accommodate thin rigid foam insulation boards to improve a home's thermal efficiency.
Are furring strips required for drywall over concrete?
Yes, in most cases, because drywall cannot be fastened directly to concrete or masonry without a framing system or furring strips.
