Breathable Hotmelt Membrane

Breathable hotmelt membranes are multilayer vapor-permeable roofing membranes manufactured using hot-melt adhesive lamination technology. The membranes generally consist of polypropylene spunbond layers combined with a functional microporous film that provides waterproofness while allowing water vapor transmission. The resulting membranes offer excellent water resistance, vapor permeability, mechanical durability, and flexibility, making them suitable for demanding roofing and construction applications where moisture management and long-term performance are required.
