SLIP RESISTANT SHEET MATERIAL FOR ROOFING AND METHOD OF MANUFACTURING THE SAME

摘要

The present document describes a slip resistant sheet material for roofing having a thickness and being adapted for a worker to walk thereon in his footwear. The slip resistant sheet material comprises a base layer and a thermoplastic layer affixed to the base layer. The base layer and the thermoplastic layer define projections and corresponding depressions transversely to the thickness of the slip resistance material whereby, when the worker walks on the slip resistant sheet material, there exists friction between the footwear and a combination comprising the projections and the thermoplastic layer thereby providing slip resistance.
