BYTUM 1500

BITUMINOUS UNDERLAY CONTROL LAYER

The BYTUM 1500 bituminous underlay control layer guarantees a very high mechanical strength, with consequent durability, thanks to its high mass per unit area. Very strong, in the version with double tape it creates a perfect adhesive joint, ensuring a quick installation and a professional sealing.

Description

The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.

Recommended use: The membrane is designed for applications on the exterior side of the roof.

It can also be used as a vapour control membrane on uneven surfaces such as concrete floors.

Installation: Unroll the membrane and fasten each layer to the substrate using a mechanical fastener to ensure installation stability.

If a membrane without integrated double tape is used, sealing must be carried out using a compatible tape such as FLEXY BAND, FLEXY BAND UV, SPEEDY BAND, or EASY BAND
