StegoHome® Below-Slab Vapor Protection

Product Information

StegoHome is a high-performance membrane designed to provide unmatched vapor protection, durability, and longevity below new home foundations. StegoHome offers a more effective and sustainable solution than generic, low-quality polyethylene sheeting historically used beneath residential concrete floor slabs. StegoHome is engineered with roll weight and dimensions suited to smaller residential project footprints and labor crews to improve installation efficiency and reduce waste.

902.3.1.1	There is a continuous gas-permeable base course under each soil-gas retarder that is separated by foundation walls or footings. The soil-gas retarder is a continuous 6-mil (0.15 mm) polyethylene or equivalent. Compliance option for 902.3(1) and 902.3(2).	Mandatory	Items 902.3.1.2 through 902.3.1.7 are also met. Mandatory for buildings in Zone 1. For Zone 2 or 3 buildings, 6 points if a passive radon system is installed OR 12 points if an active radon system is installed.
Stego vapor retarders exceed 6-mil minimum thickness requirement for the polyethylene specified as the soil-gas retarder and are engineered to provide effective soil-gas barrier in a radon reduction/mitigation system. Manufacturer’s Comments
