The sheet enclosures should be cut to ‘sheet width - 45mm‘
lengths and positioned over the tapes centrally.
With the sheets being approx. 1045mm wide this leave approx 22.5mm on each side
uncovered.
It is important that on the end of the sheet intended for the gutter that the drip
section faces down as to not impede the flow of water off the sheet. At the end
intended for the wall plate it is important to have the drip facing up to help act
as a water buffer if there are hard driving winds.
Polycarbonate multiwall sheets are UV treated, often this is only on one side. It is
important that this side is the top surface. The sheet will tell you which this is but
general practice is that the cover film with the text on is the UV protected side.
Do not remove the cover films as they will help protect the sheets and let you
know which side is UV treated.

The protective film on the sheets should be peeled back
approximately 50mm on all edges and on both sides. Ensuring
the sheet is free from dust moisture and any other debris the sheet
tapes should be applied to the two sheet ends. Vent tape for the
gutter end and and ali tape for the wall end.
