Installation Instructions
 |  1  |  2  |  3  |  4  | 

Important Installation Notes:

  1. Avoid overtightening of fasteners. Allow EPDM gaskets to squeeze slightly until full contact with the panel.
    Overtightening induces undue internal stresses, leading to premature failure.

  2. Never use washers with soft PVC (vinyl) gaskets. Soft PVC is incompatible to polycarbonate and may harm the panel.

  3. Never apply paints, shading compounds, paint thinners or any material that may chemically attack SunSky, without first verifying compatibility to the panel by contacting Suntuf Inc. or its distributor.

  4. Always work safely. Follow safety recommendations in the Installation Instructions.

  5. Maximum recommended span: Net spans should not exceed 5 ft. to avoid thermal expansion buckling. Follow recommendations in the Installation Instructions.

  6. Fastening: Always use recommended fasteners for securing SunSky panel. Never install SunSky by nailing.

  7. Isolating SunSky from harm: When placing SunSky on asphalt shingles, soft PVC or vinyl, or other incompatible materials, use an isolating barrier - metal or wooden strips, EPDM rubber patch etc. between the panel and a doubtful material.

  8. Extra Fastening: On length runs, where SunSky is overlapping metal panels on both sides, we recommend additional side stitching fasteners to the main fasteners connecting the SunSky panel to the purlins. These will be spaced along the overlapping edges about 8-12 in. apart.

  9. End/Weather Lap: At panels' width overlap-SunSky on metal or another SunSky panel, the end-lap must always to be structurally supported, to avoid deflection at that area. This also applies to ridge cap overlap.

  10. Support Profiles: At SunSky on SunSky or metal on SunSky side-lap (length overlap), use metal support profiles or wood lenght closure strips under the side-lap, to minimize deflection. The length wood closure strips should be sized to a specific corrugation - a cross section of 5/8" x 13/16" for SunSky 9".

  11. Silicone Sealants: Use only recommended silicone sealants appearing in table 2, below or those tested & approved by Suntuf inc.

    Obscure sealing or bonding materials should be referred to Suntuf inc. or its distributor for evaluation and approval.

    Unapproved sealants, adhesives or bonding materials may be incompatible and may chemically attack the panels, originate failure and revoke any and all guarranties.

    GE/Bayer Silicones


  12. Butyl-Rubber Seals: Side (length) and End (width) overlap of any type should be sealed with butyl-rubber sealing strip, placed between the overlapping panels at all edges. In roofs with shallow pitch (less than 5 percent) additional adjoining strip is recommended at width overlaps.
    Shaped End Closures: Use a profiled foam polyethylene (XPE) sealing strip to seal the space between top or bottom SunSky panel to roof edge purlin or at ridge cap. Matching XPE top & bottom strip are available for each SunSky type. It is held in place by the fasteners holding the panel to the purlin.

  13. Cleaning: Most normal dirt & dust accumulation is washed off by rain. Regular hosing of the panels with clean lukewarm water is sufficient in dry areas. In polluted, oily environment mild domestic dishwashing detergent may be used when needed, assisted by a soft rag or brush. Never use intense or abrasive cleaning agents or glass window cleaners as they may scratch or chemically attack the panel.

  14. Repair: Minor damages to the panel may be repaired. A small puncture is stopped by a dab of approved silicone sealant. A larger tear may be patched by a piece of matching panel, bonded & sealed on top of the hole with a compatible structural silicone sealant.

  15. Study and Preparation: Prior to installation study the SunSky Installation guide carefully, making sure all required materials, accessories and tools are available.

  16. Information: Please contact Suntuf Inc. regarding any applications, requests or sealants information. Contact Suntuf Inc. 1-800-999-9459.
