New call-to-action

Infiltration of moisture from the ground through concrete slabs is a major home defect liability. StegoHome 15-Mil Vapor Barrier is designed not only for effectiveness, but also for longevity. This vapor barrier is manufactured with only the highest grade of prime, virgin, polyolefin resins which allows this product to greatly resist degradation. This product is also engineered for superior strength and durability, never flakes and is resistant to tears, snags, punctures, and cracks. 

StegoHome 15-Mil Vapor Barrier has an extremely low permeance rating, which helps mitigate the risk of water vapor accumulation and the transmission of various soil gases. This helps to maintain the integrity of the building envelope and promotes better indoor air quality by avoiding serious moisture-related issues.
