The common concern for using twinwall polycarbonate sheets are the dirt, grime, and moisture that penetrate and stay inside sheet. This leads to the formation of molds which can deteriorate the quality and destroy the aesthetic value of your installed twinwall sheets.

The video below will show you how you can prevent mold formation in twinwall sheets.


The aluminum sealing tape seals off dirt, rainwater, pollens etc, from penetrating the upper or top elevated portion of the sheets. The ventilating or porous filter tape, located at the bottom of the sheet, serves as the exit point should there be any water or moisture to form inside. The U-clip, installed to cover the porous filter tape must have a clearance of 2mm, will act as the drainage channel for the water that exits the tape.
