SHEET-LIKE BUILDING AND CONSTRUCTION MATERIALS WITH HIGH WET SLIP RESISTANCE AND HIGH WATER PENETRATION RESISTANCE, AND METHODS OF MAKING SAME

摘要

Moisture-resistant materials comprise an open net-like fabric with strands of varying thicknesses and polymer film thereon. The material is both resistant to water penetration and also slip resistant under dry or wet conditions. The moisture-resistant materials are suitable for use in various applications including roofing underlayment, flashing, housewrap and other construction sheet-like materials. An optional second layer of fabric may be applied to the moisture- resistant material, for example, to improve the strength, tear resistance, and scuff resistance of the moisture-resistant material.
