Quality installation of a plywood subfloor includes gluing the plywood panels to the floor joists with construction adhesive.
Subfloor planks thickness.
The panels are also screwed to the joists or nailed with ring shank or fluted subflooring nails.
For hardwood finish flooring which average about 3 8 inch to 3 4 inch in thickness 1 2 inch to 3 4 inch thick plywood is the preferred subfloor though there are a variety of grades designed for.
All houses have subfloors.
The subfloors need to be thicker.
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.
Plywood subflooring also comes in 1 2 inch and 5 8 inch thicknesses.
Installation usually consists of nailing these boards to the floor joists.
Plank subfloors are usually made up of 3 4 thick x 4 8 wide southern yellow pine boards.
These planks are typically 1x6 pieces of wood that are nailed into the floor joists.
Plywood works as a subfloor in nearly all situations.
Not letting a subfloor dry.
Cdx plywood should be a minimum of 7 16 inch thick.
The best and most common thickness of solid hardwood is 3 4 inch 19 mm.
For joists spaced more than 19 2 inches on center the minimum thickness for plywood is 7 8 inch and for osb 1 inch.
Osb exposed during construction must be allowed to dry especially before installing sensitive finish materials such as hardwood flooring.
The thicker the board the more it costs but the longer it will last.
Plywood is the most common type of subflooring.
The oldest type of wood subflooring used in homes is made from lumber and is known as wood plank subflooring.
The thickness needed for subflooring depends on the type of floor that will go on top and the primary purpose for the subfloor.
7 16 15 32 and 1 2 inch thick panels require joists spaced 16 inches on center.
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.
Plywood comes in a variety of thicknesses beginning at 1 8 inch and increasing to 1 inch.
Older homes with squeaky flooring may have wood plank subfloors underneath which are usually made from softwoods like pine.
Always store floor panels under cover.
The thicknesses are as follows.
