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.

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
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.
