Polycarbonate Install Components: These items will yellow and get brittle. ---Reload Site
Best to use Aluminum Base & Cap System.
 
Polycarbonate H-Profile -- -- See yellowing plastic parts
• Use only in cases where sheet joining connector piece must be clear.
-
H-Profile Constraints:
• Roof purlins or wall girts must be placed 2 ft. or less on-center.
H-Profile offers minimal structural strength.
-
Drawbacks of Polycarbonate H-Profile:
• Often difficult to slide poly sheet into "H". Do Not use on arch roofs.
Sliding sheet into H-Profile on arched roof will be a nightmare.
• Less durable and less attractive than our aluminum systems.
• Not as watertight as aluminum. Especially over time as sun effects plastic.
• Service life less than the polycarbonate sheet. "H" will yellow.

Drawbacks of Plastic Base & Cap:
• Snap together & and holding features of these components not reliable.
• Do Not use on arch roofs.
• Less durable and less attractive than our aluminum systems.
• Not as watertight as aluminum. Especially over time as sun effects plastic.
• Service life much less than the polycarbonate sheet. "H" will yellow

Polycarbonate U-Profiles
--
Drawbacks Polycarbonate U-Profile:
• Does not fit tight on sheet, allowing bugs to enter cells.
• Vent tape required to keep bugs out. Now not a clear detail.
• Falling snow & ice will pull off roof sheets.
• Less durable and less attractive than our aluminum system.
• Not as watertight as aluminum. Especially over time as sun effects plastic.
Water will enter cell and start to move up the sheet.
• Service life less than the polycarbonate sheet. "U" will yellow.
