What type of TUFTEX fasteners do I use?

Screws with a EPDM washer are the recommended fastener. Screws are recommended because tightening screws to the proper depth is easier than hammering nails to the proper depth.

The washer will reduce the opportunity for water leaks through the fastening holes and provide a cushion between the fastener and panel. The fasteners must be at least 1-3/4” long when fastening through the raised ridge of the corrugation profile.

Before installing the fasteners, drill holes in the TUFTEX panels. All fastening holes must be 1/8 inch larger than the diameter of the fastener to allow for expansion and contraction of the panels from changes in surface temperature.
