Where do I position the TUFTEX fasteners?
In roofing applications, fasteners should be at least 1-3/4” long and placed on the raised ridge of the corrugation profile because water will channel into the valleys of the corrugation profile. The raised ridge is also known as the crown.
In a siding or wall application, fasteners should be positioned in the panel valleys, which will be in direct contact with the supports.
All fastening holes must be predrilled. 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.
