Depending on your sheets, you should choose the proper connector. For 0.236” (6mm) and 0.315” (8 mm) twin-wall panels, we recommend using Snap profiles or H profiles. For solid sheets and triple-wall panels, use aluminum sealing bars.
  1. Lay the bottom part of the snap profile on the wood or metal beam
  2. Screw it to the beam every 2 feet
  3. Lay polycarbonate sheets on both sides of the profile, then snap the top part of the profile.
Each connector will increase the width of the roof by 1 inch.
Option 1: Fix one sheet in place, then slide the H profile into position, ensuring it rests on the beam. Afterward, slide the second sheet into position. Screw the H Profile to the beam every 2 feet
Option 2: Fix two sheets in place with a 1.5-inch gap between them, then slide the H profile between the sheets, ensuring that the H profile rests on the beam. Screw the H Profile to the beam every 2 feet
Each connector will increase the width of the roof by 1 inch. Use a mild soap solution to facilitate easy sliding.
Connect two sheets together along the beam. Place an aluminum sealing bar on the connection line and screw the sealing bar to the beam every 2 feet.
To protect your sheet from dust, bugs, and other debris, apply aluminum tape at the top of the sheet and vent (anti-dust) tape at the bottom of the sheet. Then, install the U cap.
Length of Overhang: Aim for an overhang length of around 12-24 inches for aesthetic appeal and weather protection. However, the specific length may vary depending on factors such as climate, architectural style, and personal preference.
Overlapping is done to achieve the desired length by placing one sheet over another for 8-12 inches.
Use screws with neoprene gaskets or plastic washers. Place screws every 2 feet. For example, for a sheet measuring 4 ft x 8 ft, you will need 15 screws. Avoid over-screwing.
No need to put screws into the sheet near the connector if the connector is screwed in.
After installing all U caps and H/Snap profiles, it is recommended to apply a thin layer of silicone in the area where the connectors meet the sheet.
