LDB DUO is a breathable sarking membrane is a permeable membrane with fully integrated two-way self-adhesive strips. It is used on PAVATEX boards (ISOLAIR or PAVATHERM insulating elements). The longitudinal joints are glued into position using the integrated two-way self-adhesive strips. The transverse joints are glued with PAVATAPE 12. Screws and nails should always be sealed with PAVAFIX SN BAND. Connections and penetrations are sealed with PAVATEX sealing products. If mechanically secured.

PAVATEX stands for sustainability and ecological construction. The environmental aspect has been a key influence since the founding of the company. Effectively insulated buildings are one of the most important factors when considering cutting energy costs and climate protection measures. Through the use of PAVATEX woodfibre insulation materials, energy requirements are dramatically lowered, emissions of CO2 are reduced and carbon is bound by the structural use of wood. By connecting climate protection with living comfort, PAVATEX systems are the perfect building envelope for sustainable building projects.
