Roofing membrane |
摘要 |
A roofing membrane has a quantity of water-retaining particles fixed in the upper surface of the membrane. A fleece web affixed to the membrane surface in a quilt-like manner may provide zones of selectable size for holding the particles in place. By varying the amount of the absorber particles, the water-retaining capacity of the roofing membrane may be varied to the particular intended use, such as on a flat roof or a sloped roof.
