Screwed Joints

For the attachment of PVC foam board, basically all known through boltsare acceptable. For outdoor mounting, it is recommended that the bolt shank be passed through the PVC foam board in prepared holes or suitably dimensioned slots that leave adequate clearance between the bolt shank and the PVC foam board.The screws should only be tightened firmly enough to allow thesheet to expand and contract in all directions without warping orbuckling.

Tapping screws or screws with form fitted passage of the shank through the sheet should be avoided, but are allowed for interior uses with predictably low temperature variations.The diameter of the hole or length of the slot should not be less than 2.5 times the shank diameter of the fastener. Disc washers should be used to cover the holes or to bridge the slots and they should be large enough to ensure adequate load distribution.Precise centering of the screws in holes and slots is essential to permit free movement of the sheet in all directions.

Frame Fastening of PVC foam board

PVC foam board can be fastened utilizing various different framing materials such as, but not limited to, wood, aluminum, steel and vinyl.Besides the inherent rigidity of PVC foam board, which is dependent on thickness, all possible exterior stresses, e.g., wind pressure, etc.,must be taken into consideration in frame fastening. For appropriate mechanical and elastic property values the data sheet should be consulted. Dimensional changes due to thermal expansion (or contraction) must be taken into consideration by leaving sufficient clearance between the sheet edge and the frame.

Hanging Signs

PVC foam board may be successfully used as interior hanging signs. As PVC foam board is an extruded sheet product, thin gauges or large hanging signs may require additional support. The addition of an aluminum or thick walled plastic “C” channel across the top, bottom, or

around the perimeter may be needed to alleviate any tendencies to warp. When the additions of supporting channels are not an option, the method illustrated below may also be used to help prevent bowing. Holes should be located 2-1/2 times materialthickness from edge.
