Isola Mestermembran

Isola Mestermembran is a single-layer SBS membrane (water pressure coating) with a strong core consisting of polyester felt. The underside and welded overlap on the upper side have been coated with plastic film. The upper side has also been coated with fine sand. Isola Mestermembran complies with all current regulations. The requirements relating to Class V1P single-layer membranes (water pressure coatings) contained in NS 3530 fall easily within the specified margins.

Areas of application

As indicated by its name, Isola Mestermembran is used for covered sealed layers, such as concrete, shingle or soil. The structure above the membrane needs to be installed in accordance with standard rules. Isola Mestermembran may be used on sloping and flat structures.

Properties

Isola Mestermembran has unique strength, elasticity and flexibility – even when exposed to the extreme cold of a Norwegian winter. This membrane is thus a functional and secure solution for coping with mechanical loads or the pressures caused by subsidence or other building movements.

Laying

Isola Mestermembran is laid loose on top of the underlay and all the joints and overlaps are welded to form a watertight membrane beneath additional structures. For further information please refer to the separate laying instructions.
