A polycarbonate U-profile may be used to cap off the top and bottom of a multiwall polycarbonate sheet, preventing dust, bugs, and water from entering the sheet’s flutes. It is important to drill weep holes in the bottom edge of the U-profile to allow for proper condensation drainage.
A polycarbonate H-profile is used to join two multiwall polycarbonate sheets together, providing a finished and professional look. Technically, a polycarbonate H-profile can be installed horizontally but this may lead to potential issues with leaking. For this reason, it is highly recommended that polycarbonate H-profiles are only installed vertically, or with the slope.
Note: Polycarbonate profiles are not intended as a waterproof solution.
