waterproofing composite self-adhesive membrane for use as a vapour barrier

Pre-fabricated composite waterproofing membrane. The compound is made of distilled bitumen and elastomers (SBS type), reinforced with fiberglass and aluminium metal sheet that allows to obtain a barrier against the passage of vapour. The GECOSELF DUO VAPOUR BARRIER membrane on the exposed side features a series of stripes formed by a special heat activated compound, separated by fine sand, which ensures a strong and durable adhesion to the insulating panels. The advantages of the GECOSELF DUO VAPOUR BARRIER are basically those aimed at avoiding the use of oxidized bitumen and cold bonding substances (mastic, polyurethane glues, etc.) for the application and adhesion of insulating panels. The hot oxidized bitumen, in addition to being extremely dangerous (burns, fumes, etc.), loses in little time its adhesive capacity, exposing the covering to the known dangers due to the strength of persisting wind action and the deformations of the roof covering. In addition, the stripes ensures perfect adhesion on the entire surface of the insulating panel. In case of application on roofs with slopes higher than 15% or in a particularly windy area, it is necessary to integrate the bonding with suitable mechanical fasteners and/or strips inside in the stratigraphy. Particularly suitable for high thickness panels and/or sloped.
