Roof membranes / Facade membranes


CaPlur DaWa is a membrane for two types of application. It is designed for windproof and watertight use in façades and, simultaneously, can be used as a watertight sub-roof. The membrane consists of two-sided, highly diffusion permeable, weldable TPU coatings with embedded polyester nonwoven material and meets the requirements of the standards and technical regulations for flat sloping sub-roofs, as well as the requirements of the standards for façade membranes.

CaPlur DaWa is produced in two colours, which indicate the two application areas. The black side has an increased UV-protection, to allow façades with open joints up to a maximum of 5 cm and an open joint fraction of up to 40%, the grey side is designed for the watertight sub-roof. The multifunctional membrane can be welded at the seams and allows easy windproof and watertight connection from the roof to the wall.

When working with the material it is necessary to observe the applicable standards, the generally recognized rules of manufacturers as well as the CaPlast laying information. Subject to technical modifications.
