This construction assumes the use of fiber cement corrugated sheets.

Please refer to the manufacturer's prescriptions for the mounting of the corrugated sheets.

For buildings with internal climate class IV or a building in overpressure, extra attention has to be paid to the seam finish.

In exceptional cases when condensation cannot be avoided, the draining of condensation water may be considered to be done via the corrugated sheets, taking account of the required seam sealing of the roof.

LEGEND

1. Corrugated sheet
2. Bearing lath (50 x 70 mm)
3. Waterproof elastic tape
4. EUROTHANE
5. "W" type border finish
6. Z-profile
7. Bearer

Possible condensation leaks can be drained via the insulating board.

The corrugated sheets can be mounted directly on the insulation (see mounting on top of the bearers : metal sheets).

Their mounting is recommended on a substructure of double lathing.

When only horizontal auxiliary bearers are used, these will be interrupted at even distances (preferably at height of the insulating board's center) to ensure the drainage of condensation water.

The border finish - type "W" combined with matching Z-profile and sealed on top with a waterproof, elastic tape - ensures a continuous insulating shield.
