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

GECOSELF HP V.B. are pre-fabricated waterproofing membrane for specific use as a total barrier to the passage of vapour. GECOSELF HP V.B. has a continuous single strand composite woven non woven polyester reinforcement with high mechanical characteristics and an aluminium film which allows to obtain a barrier to the transmission of vapour. The lower face of GECOSELF HP V.B. is protected with a removable silicon release film. The upper face is self protected with micro mineral slates that offer good walkability and improve grip of TECA adhesives (Pratiko Mastic, Bit Adhesive, etc.) for the adhesion of insulating panels; furthermore a removable side selvedge of 10 cm is foreseen. In the stratigraphy of the roof, GECOSELF HP V.B. must be applied under the insulating panel, in order to preserve the latter from the condensation phenomena of water vapor, which certainly occurs, as the roof operating conditions change. GECOSELF HP V.B. is an innovative self-adhesive with increased adhesiveness, enhanced resistance of the adhesion to aging and the cold (the product maintain good adhesion even at low temperatures). The GECOSELF HP V.B. membranes are capable of resolving specific application and functional requirements and present numerous and important advantages, such as ease of application with consequential savings on time and the possibility to apply the material on surfaces which are not suitable to open flame. Therefore GECOSELF HP V.B. is insuperable in the waterproofing of wood structures, insulation panels which are heat sensitive, panel decks and refurbishment of historical roofs. GECOSELF HP V.B. guarantees a perfect level of adhesion to the application surface, providing the system with an excellent level of wind uplift resistance and allowing accidental infiltrations to be traced.
