PE Foam tape PRODUCT DESCRIPTION This Access Tape is a roofing purlin tape used when installing polycarbonate roofing. Providing a professional touch, the use of purlin� tape between wooden rafters and polycarbonate roof sheets� reduces the crackling noise that occurs as the polycarbonate� sheeting expands and contracts slightly during weather fluctuations.
