How Many Plywood Clips Per Sheet

When used for spacing we only place 2 clips per piece one at each end.

How many plywood clips per sheet. 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. Here in southeast nc we use h clips not only for structual reasons but also for the 1 8 inch gap between the sheets. H clips provide additional stiffness between bearing points for the unsupported edges of wood panel plywood or osb roof sheathing along with the necessary 1 8 gap for expansion as shown below illustrated on a bag of simpson h clips. It depends on your truss spacing 1x each truss span.

4 feet equals 48 inches which you then divide by 8 to determine that you ll need six nails where the board comes in contact with a truss. Nail spacing for sheets of osb and plywood is 8 inches per nail. So dividing the area of the roof by 32 will give you the number of sheets needed. A 4 8 sheet of plywood is 32 ft 2.

Plywood clips clips are designed to be placed in between two rafters to minimize the span in other words they are meant to almost serve as an additional rafter there should be no need for clips with 19 32 osb 24 o c for standard roof application unless you are working on a flat roof. Once you have the area you can divide by the area of a sheet of plywood to find the number of sheets needed. For example if your roof is 1 500 ft 2 then it will take 47 sheets of plywood to sheath it. 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.

Yeah i know what you guys are saying just use a nail gap. This means that you ll need to use six nails per each truss that runs under the sheathing because each sheet measures 4 feet wide by 8 feet long. Common thickness of the h clip sheet metal is between 18 and 20 gauge 0 052 inch 1 31 mm and 0 040 inch 1 01 mm. Plywood clips are available in sizes to match nominal plywood thicknesses.

A 4 8 sheet of plywood is 32 ft 2. Proper structural function of the clips require they match the thickness of the plywood panels being used. Its just faster and more uniform ocean state builders inc. Additional plywood clips can be added to maximize load bearing in a specific area but the minimum clip placement described should be maintained in general.
