Breathable Reinforced Hotmelt Membrane

Breathable reinforced hotmelt membranes are high-performance multilayer roofing membranes designed to combine vapor permeability, waterproof protection, and enhanced mechanical strength. The membranes consist of polypropylene spunbond nonwoven outer layers, a functional microporous film, and an integrated reinforcing grid made of polypropylene, or rarely of polyester. The reinforcing grid significantly improves tensile strength, tear resistance, and installation safety. These membranes are intended for roofing and building envelope applications requiring superior durability, dimensional stability, and resistance to mechanical stress during installation and service life.
