uPVC Sheet Closures are used to protect and finish the end of the polycarbonate sheet (or glazing panel) at the gutter end of the panel.
They are designed so that a 2mm air gap is created between the end of the panel and the inside of the sheet closure.
Having a sheet closure does not negate the need for breather/anti-dust tape at the gutter end of the panel.
It should be cut to fit between glazing bar top caps and flush with the ends of the glazing bars.

Fitting Tip - Apply a bead of silicone to the upper edge of the sheet closure (all along, underneath the top edge). Do not over silicone, as the air needs to circulate around the breather tape, so moisture can evaporate.
