STEGO® WRAP Class C Vapor Retarder (10-Mil)

A Reliable and Cost-Effective Solution to Reduce Moisture Migration

Stego Wrap Class C 10-Mil Vapor Retarder is manufactured with a specific, advanced blend of premier polyolefin resins and additives to provide outstanding performance. This Class C Vapor Retarder is commonly utilized under below-grade interior slabs to reduce the amount of moisture vapor migrating from the ground into the building's concrete slab. 

The Stego Wrap Class C 10-Mil Vapor Retarder provides protection in a broad range of environments and may also be used in systems for the reduction of soil gas (radon and methane) migration. While still exceeding ASTM E1745 Class product requirements, Stego Wrap Class C 10-Mil Vapor Retarder provides an economical option for projects. 

Its many features include:

  • Durable enough to prevent punctures and tears in light foot traffic construction conditions
  • Helps shield from soil gases such as methane and radon
  • Aids in protection against flooring failures
  • Superior performance protection when compared to generic, recycled 6-mil poly
  • Less vulnerable to deterioration when compared to generic, recycled 6-mil poly
  • Exceeds ASTM E1745 Class C
  • Made in the USA

Vapor Barrier

Stego Wrap Class C 10-Mil Vapor Retarder has low permeance, providing a high level of protection for a vapor retarder. Not as durable as the Stego Wrap Class A 10-Mil Vapor Retarder, this product can be an economical benefit in construction with light-machine or foot-traffic-only construction conditions. This product is compatible with Stego’s myriad of installation accessories, helping to meet the installation requirements of ASTM E1643.

Engineered Performance – Life of the Building Protection
Stego offers the first-of-its-kind warranty for its line of vapor barriers and retarders. The Stego Life of the Building Warranty reinforces its 20+ year track record without a single claim of product failures, making Stego the construction industry leader in below-slab barriers. The warranty matches the unparalleled Stego Installation Support - a FREE SERVICE designed to help achieve an effective installation and add value for project teams.
