PVC U profile to be used at the gutter end of each sheet. These profiles are2100mm in length. This profile protects the breathable ventilated tape that we put on each sheet of polycarbonate and stops the tape from damage due to weather. As a result nothing will be able to enter the sheets and they will stay looking good for longer.
These U Profiles clip on to the end of the sheet. Some installers choose to use silicone on the inside to help keep them from loosening in windy conditions.
