specifications vapour vapour barrier

vapour barrier · simple and efficient The vapour-barrier’s utility The difference of temperatures in winter between heated indoor areas and weather conditions creates vapour which seeps through roof layers. Without a vapour-barrier, it reaches a particular zone called the dew point where it may take a liquid form. This type of condensation causes: n Stains and wet trails under the ceiling. From slight humidity in the insulating layers to total impregnation. This type of phenomenon results in a loss of thermal resistance and, consequently, a drop of temperature in the wall, thereby increasing...

simple and efficient · vapour barrier DESCRIPTIVE CLASSIFICATION FOR INFORMATIVE PURPOSES ONLY Found below, is a theoretical classification of the most common types of indoor areas in terms of their use, purpose and conception according to French regulations. 1 Indoor areas exposed to slight levels of humidity. - Offices without air-conditioning, rooms equipped with controlled mechanical ventilations and air vents adapted to the presence of vapour. - Warehouses. - Rooms designed and equipped for indoor sports or exercise with no public admittance, (outbuildings not being into account). Indoor...

Vapour-barrier composition The choice of the best-suited vapour-barrier should be made according to the nature of the support member, the hygrometry of the area and the installation method, in accordance with the French standard and with the specific technical document for waterproofing systems. SBS MEMBRANES Support member Hygrometry and indoor heating Applied with hot bitumen Applied without hot bitumen 12 Typical cases Heated floors providing partial heating Primer + hot-applied bitumen + BARAL Closed areas with strong hygrometry and heated floors ensuring the whole heating system Primer +...
