Each sheet consists of an 'over rib' and an 'under rib' and when put together they form an effective seal preventing water entry.

Laying (Ribs Vertical)

Start at the end of the wall which is away from the prevailing weather. The over?edge should be as shown:

Laying (Ribs Horizontal)

The edge laps must face downwards with the over edge on top as |shown. If end laps are necessary on long runs, allow 75mm per lap. End laps should be sealed with suitable sealant.
