Stego Wrap 20-Mil Vapor Barrier is used as an under-slab vapor barrier. This Vapor Barrier is developed from the same proprietary blend of prime virgin resins and additives as the popular Stego Wrap 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.
