drainage waterproofing membrane / roof / roll / polyethylene
USB DRENLAM LIGHT
USB DRENLAM LIGHT is a three-dimensional layer composed of extruded polyethylene monofilaments with carbon black (UV stabilized), with isometric pyramid morphology, creating a separate drainage and sound-proof layer against the noise made by rain and hail, used underneath metal roofs (metal sheet, copper, titanium zinc, etc.) thanks to the effective soundproofing provided by the extreme elasticity of its monofilaments.
USB DRENLAM LIGHT is a drainage and sound-proof layer which separates the metal roof covering from any waterproofing layer laid previously on the roof; this layer makes it possible for any condensation forming underneath the metal roof covering to escape and reduces the noise caused by rain and hail hitting the roof.
