Squash Blocks – are short pieces of lumber or EWP cut 1/16” longer than the depth of the joist. Their purpose is to transfer vertical loads around the joists to bearing below. Squash blocks do not provide lateral support.
Two common reasons for squash blocks are:
- To carry load-bearing walls that stack above walls (or beams)
- To carry concentrated loads from above through the floor
