Protection &

Bituminous strip

The NÖVLEK® bituminous strip protects the upper surface and sides of the joist from water. Because it is waterproof, water runs off and is discharged easily.

Ventilation Shims

NÖVLEK® ventilation shims ensure perfect ventilation of the underside of the boards, and prevent water retention at the contact point between board and joist.

Isolation Shims

The NÖVLEK® isolation shims isolate the timber joists from the ground and ensure they always stay dry. The use of NÖVLEK® isolation shims prevents the risk of degradation and premature rotting of joists.
