This U Profile End closure fits on the bottom of the polycarbonate roofing sheet in the gutter and on the top for finishing (if a freestanding pergola).
It has a lip on the bottom, which acts as a drip to stop water being driven underneath the sheet.
For use with all Multiwall polycarbonate sheets, internal stop ensures gap for ventilation.
Use strip to close the open ends of Twinwall or Triplewall Polycarbonate sheets to prevent dirt, water or insects getting inside.
Use Silicone Sealant to bed sheets into the U-Profile at the top end of the roof; at the foot of the sheets fit Dust Seal Tape before clipping U-Profile over the top.
Here at TW Plastics, we supply the U Profile End Closures in 2.1m lengths, in Brown or White and for use with either 10mm, 16mm or 25mm Polycarbonate.
