Different plywoods use various materials and methods of manufacture depending on the application for which they re intended.
How many sheets of plywood for a subfloor.
The stapler saves a lot of time.
This method only measures subfloor thickness.
My current subfloor appears to be 3 4 plywood picture attached.
This simple sub floor materials calculator will provide you with the lineal feet of floor joist needed the number of sheaths to cover the floor and how much glue and how many screws it takes to attach the sheathing to the joist.
Meanwhile osb compacts as many as 50 layers of strands into a single sheet the same thickness as that plywood ensuring a much denser and heavier product throughout.
800 32 25 sheets.
A 4 8 sheet of plywood is 32 ft 2.
Cdx plywood should be a minimum of 7 16.
You want to choose fasteners that will not penetrate the bottom of the subfloor.
Whenever you re laying tile on a wood subfloor you need to first install cement backerboard to prevent leaks and water damage.
This means that for 7 16 underlayment and 23 32 subfloor the longest fastener you can use is 1 1 8.
Adhesive will help you here as the subfloor plywood will have voids in spots that will not hold a fastener.
The screw count is a bit high at times but this will allow for losing some.
There are many types sizes and configurations of plywood.
It s available in sheets of many sizes with 3 foot by 5 foot sheets being the most common.
Plywood is a popular choice for residential and light duty construction and is made from thin sheets of veneer that have been peeled from debarked wood.
Glue is sprayed between each layer and the sheet is hot pressed.
Cdx plywood is traditional wood plywood made from thin layers of lumber known as veneers.

Cement backerboard is a thin layer of concrete with fiberglass mesh on both sides.
These thin layers also called plies are glued together in alternating perpendicular directions to create a cross graining pattern.
For example if the area to be covered in plywood is 800 ft 2 then 25 sheets of plywood will be needed to cover it.
Divide by the total square footage by the square footage of a sheet of plywood to find the number of sheets required to cover the space.
But combined with other methods that measure the finish floor you can get a fairly accurate reading of total floor thickness.
A subfloor is a wooden structural substrate to which durable finished flooring is attached.
