K. Recommended Washers & Fasteners
Use of recommended fasteners and washers, along with careful execution according to the installation instructions is essential for
maximum product performance. Palram brand EPDM-washered fasteners for Sunsky have been tested and certified to be compatible with
polycarbonate, whereas other brands may not be. Incompatible washers can result in panel failure that is not covered by warranty.
Contact your Palram representative for availability. For fasteners shown below, pre-drill fastener holes with a 3/8" drill bit to accommodate
thermal expansion & contraction of the panel. Over-size holes by an extra 1/8" for other fastener diameters. Failure to accommodate for
thermal movement may cause buckling of the sheet and, potentially, eventual failure. Fasteners shown below are available from Palram.
* Mechanically Zinc Coated Carbon Steel fasteners are designed to withstand years of exposure to Mother Nature’s most tortuous elements, however, if installing
SunSky in a location with above normal exposure to salt-air, chemicals, or pollutants, use 304 Stainless Steel fasteners (see Dealer for details).
