Stego Wrap | Class C Vapor Retarder (10-mil)

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

Case Studies

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.
