Introduction: Pro-Sky is a high quality light-transmitting, corrugated polycarbonate panel designed to match Pro-Rib and Premium Pro-Rib panels. It is designed for single or multi-panel skylights or side lights in roofs and walls of metal-clad structures.
Transportation, Handling & Storage: 1. Transport and store Pro-Sky panels horizontally on flat, sturdy pallets, equal to or longer than the longest panels. Short panels should be stacked on top of longer ones. The panels should be secured and fastened to the pallet during transportation. 2. Store Pro-Sky panels in a cool and shaded place, out of direct sunlight. Avoid covering the stack of panels with dark or heatabsorbing materials or objects, to prevent solar heat buildup. 3.
Safety Measures (during installation and afterwards): 1. Use ladders, crawling boards and other safety equipment required for safe installation. Be sure to wear appropriate personal protection equipment such as proper gloves, safety glasses, etc. Use all safety measures required according to local safety regulations. 2. Always use appropriate scaffolding to service panels. Scaffolding should provide proper worker safety and ensure proper placement and distribution of weight to avoid damage to panels.
3. Uplift Testing: Pro-Sky corrugated polycarbonate panels meet Uplift Test Criteria specified in UL 580 Test for Uplift Resistance of Roof Assemblies (UL Class 90). Consult Palram Americas technical support for additional details if necessary. Test Description Roof Covering: Corrugated polycarbonate roof panels with 9 inch spaced corrugations. The tested material comes in 0. 032" thick x 38" width and 12 feet long.
Installation Comments (Roofing & Siding): 1. Single Panel Run Installation: The length (long side) outermost crests of a Pro-Sky panel should lap over matching adjacent crests of metal panels on both sides. 2. Multi-Panel Run Installation: The middle Pro-Sky panels should be installed with the regular under/over length overlap (the short crest edge on top of a longer one).
Fastening & Sealing: Pro-Sky At edge purlins At internal purlins 5. Installation & Fastening Tips: a. Allow for expansion & contraction at fasteners: Pre- drill screw holes 5/64" larger than the screw size to allow for expansion and contraction of the panel. Use #10 wood screw or #12 self-drilling/self-tapping screw with a minimum of 1/2” neoprene bonded washer. Pro-Sky panels are not installed below 40°F or above 80°F. See Page 17, Table 3, for detailed Pro-Sky Thermal Expansion Data. b.
6. Sealing Pro-Sky: a. Self-Adhesive XPE Sealing Tape (Expanded Cross-Linked Polyethylene): Resilient, closed cells, self-adhesive foamed-polyethylene to be applied at sides & end-laps, on top of the overlapped area. Cross-section dimensions may vary according to specific requirements. A typical XPE tape is 3/4" (20.0 mm) in width, 3/16" (5.0 mm) in thickness and comes with pressure sensitive adhesive on one side, protected by silicone paper.
Side & End Lap Installation: End lap (or width overlap - short side) of a Pro-Sky panel on another consecutive Pro-Sky or metalpanel, should always be done over a supporting purlin. Each of the panels involved should overhang the purlin center-line by about 3" (2" minimum and 4" maximum), totaling an average overlap of 6".

Options for Installation: 4 1. Single width, single span installation (on 2 edge support purlins), integrated and surrounded by matching metal panels, overlapped on top, overlapping and supported on both sides and at the bottom. This dictates that the top metal panel is also installed with its edge corrugations overlapping at both sides, up to the roof edge or ridge.
2. Single width, multi-span installation, on a few support purlins, using one single long panel or a few consecutive ones, overlapping each other (See Single-Panel Runs, page 7, fig. 9). This option can be implemented by two possible alternatives: • Installed mid-field, surrounded by matching metal panels, overlapped on top, overlapping both sides & bottom. • Installed from top to bottom or from ridge to bottom (one or two way pitched roof ).
5. Installing Pro-Sky Side Lights on Exterior Walls: When installing, fastening and sealing side lights, follow the same general procedures for roof installation as described on the preceding pages. Certain installation methods are specific to siding installation, like the framed Side Light.
Important Installation Comments: 1. Avoid over-tightening the fasteners. Allow gaskets to squeeze slightly until full contact with panel. Over tightening induces undue internal stresses, leading to premature failure. Regular Washer / Gaskets (Tek Screws) for metal panels apply excessive pressure, are inadequate for Pro-Sky sealing, and cause undue internal stresses in the panel. The stresses result in crazing, fractures, and eventual failure. 2. Never use soft PVC (vinyl) washer / gaskets.
. Cleaning: Most normal dirt & dust accumulation is washed off by periodic rains. Regular hosing of the panels with clean lukewarm water is sufficient in dry areas. In polluted, oily environments, mild household detergent may be used, assisted by a soft rag or soft-bristled brush. Never use aggressive or abrasive cleaning agents or glass window cleaners. They may scratch or chemically attack the panel. Large areas can be washed by high-pressure water-jet, optionally, in conjunction with diluted detergent.
