Subfloor Planks Thickness

The subfloors need to be thicker.

Subfloor planks thickness.

Older homes with squeaky flooring may have wood plank subfloors underneath which are usually made from softwoods like pine. For joist spacing of more than 16 inches up to 19 2 inches on center the minimum thickness for both plywood and osb is 3 4 inch. A thicker the veneer wears longer. Plank subfloors are usually made up of 3 4 thick x 4 8 wide southern yellow pine boards.

Typically made of plywood or osb and ranging in thickness from 19 32 to 1 1 8 thick the subfloor is truly structural second only to joists in this respect. Edge gold includes patented down pore grooves that help shed standing water and a proprietary edge seal to reduce edge swell. The best and most common thickness of solid hardwood is 3 4 inch 19 mm. Plywood works as a subfloor in nearly all situations.

Subfloor holds up all of the above layers of flooring as well as everything in your house people dogs cats pianos furniture. All houses have subfloors. Quality installation of a plywood subfloor includes gluing the plywood panels to the floor joists with construction adhesive. The oldest type of wood subflooring used in homes is made from lumber and is known as wood plank subflooring.

Not letting a subfloor dry. These planks are typically 1x6 pieces of wood that are nailed into the floor joists. Osb exposed during construction must be allowed to dry especially before installing sensitive finish materials such as hardwood flooring. The thicknesses are as follows.

For joists spaced more than 19 2 inches on center the minimum thickness for plywood is 7 8 inch and for osb 1 inch. Plywood is the most common type of subflooring. Installation usually consists of nailing these boards to the floor joists. The thickness needed for subflooring depends on the type of floor that will go on top and the primary purpose for the subfloor.

Cdx plywood should be a minimum of 7 16 inch thick. Plywood comes in a variety of thicknesses beginning at 1 8 inch and increasing to 1 inch. The thicker the board the more it costs but the longer it will last. Always store floor panels under cover.

The panels are also screwed to the joists or nailed with ring shank or fluted subflooring nails. For engineered floors there are two components that make up the thickness the base layer or core and the veneer.
