Preparations Prior to Installation
1. Ensure smaller thermal expansions by installing sheets - especially colored sheets - at ambient temperatures of 10-25 °C (50-77 °F).
It is generally recommended to avoid installing sheets at colder or hotter temperatures.
2. Peel off the protective film at both open ends of the sheet (the width sides) to about 80-100 mm (3.5-4 in.) from the edges of the
sheet, to enable taping of the aluminum sealing tape. If a factory installed temporary seal is taped over the open ends, it should be
removed prior to the installation of the aluminum tape. Tape the sealing tape straight along the open-end side, so it will cling well
and evenly to both sides of the sheet, making sure that all the open ends of the rib channels are properly sealed.
3. Peel off the masking along the edges of length sides at both sides of the sheet, for about 80-100 mm (3.5-4 in.) from the edges,
preparing the sheet for the insertion into the connecting profiles or the glazing frame.
4. Remove the underside masking just prior to the actual installation on the roof. Premature removal of protective film may result in
damage to the sheet during handling.
5. Remove the upside, exterior protective film as soon as the installation of the whole glazed area is completed, or very short time
afterwards. Failing to do so would expose the protective film to direct sunlight that may fuse it to the sheet’s face. This will result in
difficulty to remove the protective film due to deterioration of the film, and ultimately void the warranty.
6. Ensure the use of the proper type of sealing tape according to the application used, verifying that the prepared sheets are mounted
correctly.
Please note: In case of curved installation, where both open ends are situated at the bottom - apply the ventilated tape on both ends.
Take care to protect the sealing tapes at both ends from mechanical damage by covering the edges with aluminium U-profiles, or
cover them with polycarbonate U-shaped profiles (Fig-17c).
Glazing Profiles & Fastening Screws
Type of glazing/clamping profile used in the installation of SUNLITE sheets, differs according to the glazing system chosen:
1. Framing profiles are similar in concept and detail to those used in fixed glass windows, curtain walls and skylights, made of wood,
steel or aluminum, but wider, allowing for the larger Edge Engagement depth required for SUNLITE. The frames are prepared in advance,
and glazing is done after they are all in place, along with completion of the other finishing jobs. (See Figures 3a, 3b).
2. Two and four-sided clamped glazing employ practically the same profiles used for framing, as used in curtain walls and skylights.
Almost all are prepared prior to the glazing work, and just the clamps, the rubber packing profiles (and silicone sealant in ”wet” glazing)
are installed along with or after the glazing is in place.
3. The roofing and cladding glazing installation method installs SUNLITE over the supporting skeleton, rafters and purlins. The glazing
profiles, which are usually flatter by design, consist of top and bottom parts, made of polycarbonate, rigid PVC or a combination (a
bottom aluminum profile and top profile made of polycarbonate, or rigid PVC). SUNLITE sheets and their connecting profiles (also
acting as glazing profiles) are installed together, advancing step by step. Most profiles are flexible enough to be easily shaped into
curves by hand, when installed over curved structures, enabling inexpensive implementation of curved glazing.
