Can 2×4 be used for floor joist?
A 2×4 can span a maximum of 6′ 7” when spaced 16” apart and used as a floor or deck joist. When used as a ceiling joist or a roof rafter, a 2×4 can span up to 7′ 3” spaced at 16”, and 6′ 4” when spaced 24” apart. Due to the small spans of 2x4s, they often are not used in horizontal load-bearing capacities.
What size timber should I use for floor joists?
As a general rule – floorboards should be a minimum 16mm thick for joist centres up to 500mm and 19mm minimum for centres up to 600mm.
What goes on top of floor joists?
Subfloor A subfloor is a layer between the floor underlayment and the joists. Its sturdy structural part rests on top of the floor joists and acts as a foundation for the underlayment and the floor covering.
Do floor joists have to sit on a beam?
Floor joists spread the loads bearing from above, and must be framed adequately to complete the load paths. Ideally, if a load-bearing wall runs parallel to floor joists, then it should sit directly over a beam or a joist supported by a load-bearing wall below.
Do you install subfloor before framing?
If you use a product like DriCore for the subfloor, they even explicitly recommend you frame on top of their subfloor product. They do, however, recommend you screw the framing through the subfloor into the concrete with something like 3″ Tapcons spaced every 4 ft through the bottom sill of the framing.

What is a hybrid timber frame home?
By using our hybrid timber frame building system, we combine the strength and efficiency of structural insulated panels (SIPs) for your walls and roof with exposed, load bearing timbers. These resulting homes are architecturally distinct, energy efficient, and sustainable. They embody our standard — Artful, Rugged, Green.
