H Clips Roof Sheathing Spacing

Plywood clips also referred to as h clips or panel edge clips are small metal brackets placed between the unsupported edges of plywood sheathing to effectively reduce the support spacing and stiffen the plywood.

H clips roof sheathing spacing.

However it is not a requirement. Some older h clips do not provide a built in gap. The clips are inserted over the edges of the adjacent plywood panels to reduce deflection of the panel edges between the framing members and are most commonly used for roof sheathing. However two 2 equally spaced h clips are required between supports when spaced 48 inches on center.

Help prevent sheathing warping our clips leave a precise 1 8 gap created from a full width spacer bar. Simpson strong tie panel sheathing clips are used to brace unsupported sheathing edges and provide a 1 8 gap to address shrinkage and expansion of roof sheathing. Use a 10d box nail to gauge 1 8 inch spacing between panels. What h clips do 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.

H clips must fit snugly. One h clip shall be placed between abutting panels at a location midway between each pair of trusses rafters or joists. Reduce frustration of clips falling off or spearing edge of sheet full length expansion bar gives you superior alignment and perfect expansion gap. Some manufacturers may require a space at the time of installation.

H clips for roof sheathing grip h clips are designed to make installing roof sheathing faster with better spacing. Not always required but a good idea. Zip system roof assembly combines our revolutionary integrated sheathing and flashing tape or liquid flashing to provide a sealed roof for protection against moisture intrusion during construction or if high winds strip the roof covering away. Use the same size panel edge clip as the panel thickness.

A strong resilient roof is a home s first line of defense when the roof deck is exposed to weather.
