Stego's cutting-edge 20-Mil Vapor Barrier is developed from the same proprietary blend of prime virgin resins and additives as our popular 15-mil barrier, and provides additional protection for crucial projects. This advanced multi-layer plastic extrusion blown film vapor barrier provides unrivaled moisture protection in even the most unforgiving conditions, such as intense fluctuating temperatures and humidity, and is frequently used on high-profile projects such as data centers and hospitals.
Its many features include:
Stego Wrap 20-Mil Vapor Barrier has an extremely low permeance which is below current industry standards for products of its kind. Our vapor barrier has a baseline water vapor permeance rating of 0.0071 perms and puncture resistance exceeding 3500 grams, making it a Class A product per ASTM E1745. After being conditioned to cycles of wetting and drying, heat, low temperature, and soil organisms exposure, tests on permeance ranged from 0.0077 perms to 0.0088 perms. The 20-mil barrier provides control against water vapor and soil gases.
Since this product is not made with recycled materials and instead uses prime, virgin resins, the vapor barrier will greatly resist degradation. The product is engineered to provide superior strength and durability, never flaking and resisting tears, snags, punctures, and cracks.
