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. It prevents run-off water penetrating the many cracks and splits in the wood, which appear after a while, especially around screw holes. It avoids wood-on-wood contact, and also any rising damp.
It is strongly recommended for wooden joists with a natural durability classification greater than 1.

Overhanging
The NÖVLEK® bituminous strip is 60, 80 or 100 mm wide, so it overhangs either side of the joist, whether laid along its narrow or wide side.

Umbrella effect
The overhanging edges of the strip curve slightly after laying, giving it an umbrella shape which prevents water running along the sides of the joist.

COMPLIANCE DTU 51.4

NÖVLEK® bituminous strip complies fully with the requirements of the NF DTU 51.4 standard as regards protection of the upper surface of the joists.

USE

using the NÖVLEK® bituminous strip prevents the risk of damage and premature rotting in the joists.

Quick and easy to lay

Some widely-spaced staples or nails are sufficient to hold it in place, before the boards are laid.
The strip unrolls and aligns itself automatically on the supporting surface, thanks to its exceptional stiffness.

1.9mm for maximum shock-absorption

The composition of the strip and its 1.9 mm thickness give it outstanding absorbent and shock-absorbing qualities, ensuring unbeatable comfort.

Additional to the ventilation interface shim

The bituminous strip protects the joist, while the ventilation shim ensures the underside of the boards is ventilated by separating them from the joist. Both guarantee durability of the decking

The joist is no longer visible

The bituminous strip conceals the joist completely in the spaces between boards.
