H-Profile

Polycarbonate Install Components: These items will yellow and get brittle.
Best to use Aluminum Base & Cap System.

Polycarbonate H-Profile,      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.

Avoid Plastic Base & Cap Systems

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.
