What is StegoHome?

StegoHome below-slab vapor protection is a multi-layer plastic extrusion manufactured with only high-grade, prime, virgin, polyolefin resins designed to provide unmatched protection for the underside of new homes.

An extremely low permeance to vapor, as well as exceptional durability and longevity makes StegoHome an important component to a home’s envelope in all climates and geographic locations given the natural movement of sub-slab vapor.

Why should I use StegoHome?

StegoHome is used as below-slab vapor protection for moisture and other soil gases, like radon, and specifically engineered with roll weight and dimensions suitable to smaller residential footprints and labor crews.

For builders and homeowners, StegoHome offers an effective and permanent solution to help prevent potential costly failures and unsafe conditions within the home over time, including damage to foundation and interior components (like flooring), mold growth, and poor indoor air quality.
