If warmth is not a priority, and the installation of drywall is still required on the perimeter basement walls, then furring strips can be attached to the perimeter walls instead. Furring strips usually consist of 2”x2”s that are glued and nailed to the concrete basement walls.

Internal Basement Wall Framing

The internal walls can be built on the ground and then simply raised in place, however due to inevitable variations in basement floor heights the walls should be built slightly shorter and then shimmed into place.

These clips will enable the basement walls to breath (move up and down), but give the support necessary to ensure the wall remains vertical.

When framing basement walls there are typically many obstructions (pipes, duct work) that you need to build around. Thus, it is sometimes easier to stick build walls around these types of obstructions.

To stick build basement walls, first nail a top plate perpendicular to the floor joists. Next, secure a bottom plate to the concrete floor using concrete nails and an adhesive such as Liquid Nails. Make sure you use pressure treated lumber on the bottom plate as it is in contact with the concrete and will wick moisture over time. The top and bottom plates should be parallel to each other. Use a plumb line to ensure they are parallel.

Next nail the bottom plate to the two studs to create the basic wall. Finally, install on 16” centers, 2”x2” studs along the entire length of the plates. Pending the situation you may need to build the same framing structure on the other side of the ductwork. Once you have completed the second soffit wall simply install 2” x 2” cross member stud pieces (lookouts) between the two soffit wall sections. You will want to make sure you use a chalk line and a level during this task to ensure the soffit walls remain straight. Again, as the soffit is being stick built, measure every stud prior to cutting.

Framing the Ceiling

If drywall is to be installed on the ceiling then you may need to add effectively a horizontal wall. Basically the same process is done as with building soffits, however 2”x4”s are used for providing clearance for pipes hanging below the floor joists. If there are no pipes or wiring hanging below the floor joists, then 1’x3” strapping may be able to be used. Simply nail them perpendicular to the floor joists on 16” centers.
