DIFBAR Efficient watertight and breathing protection
Difbar is a membrane consisting of a special vapour-permeable layer (SD = 0.02 m) heat-sealed between two layers of protective fabrics. Diftbar guarantees exceptional vapour permeability, as well as excellent waterproofing. Diftbar is applied above the insulating material and prevents the formation of condensate. Furthermore, it offers watertight protection against roofing leaks during building works.
