Floor Thickness Wood Construction

Floor joists are typically 2 by 8s 2 by 10s or 2 by 12s.

Floor thickness wood construction.

There are two main types of subflooring plywood and oriented strand board or osb. Is 23 32 inch osb or plywood. Details for conventional wood frame construction. Both come in 4 by 8 sheets and feature tongue and groove installation.

Such methods use a 4 foot design module which governs a 16 inch spacing of joists. The national wood flooring association s brett miller explains why minimum building code for joists and subflooring isn t always sufficient for wood flooring. For joist spans 16 inches or less nwfa recommends minimum panel thickness of 5 8 inch plywood or 23 32 inch osb. The building code requires 5 8.

3 4 inch solid this is a 3 4 inch thick solid piece of hardwood floor and what you might typically think of for hardwood floors. Laminate floors with a thickness of 12 mm to 15 mm feel more like hardwood floors than thinner laminates. It is an ideal building material for subfloors. Ceiling joists are usually 2 by 6s or sometimes 2 by 4s if it is an older home.

Some newer homes have manufactured i beam shaped joists. A floor s framework is made up mostly of wooden joists that run parallel to one another at regular intervals. The first approach to achieving a strong durable struc ture involving economical use of materials is to follow a basic modular plan for layout and attachment of framing members. The bulk of the floor s thickness comes from the joists which are the horizontal beams that carry the floor s weight.

Because solid floors expand more when exposed to moisture than engineered floors you can only install them over a plywood subfloor at or above ground level. Construction adhesive is used between the joists and the subfloor but it does not measurably add to the thickness of the floor. For retrofitting older construction 23 32 and 3 4 inch thick panels can be used over 24 inch on center joists. Subflooring only adds 3 4 inch to the floor thickness.

Usually manufactured in 4 by 8 foot sheets plywood panels and osb are acceptable subfloors for hardwood flooring as long as they are the proper thickness. Joists in home construction are usually made with 2 by 10 or 2 by 12 lumber. Depending on if what the floor finish will be tile hardwood or carpet there are different recommendations for the actual thickness of the plywood you ll need.
