Overview

CS Fabric Prime Wrap PR-4575 is a high‑performance house wrap designed for modern wall assemblies. This woven and coated polyethylene fabric features micro‑perforations that function as a water‑resistive barrier, an air barrier, and a moisture protection layer. Suitable for both residential and commercial sidewall construction, it helps create a protective envelope around a building while remaining straightforward to handle on site.

Key features

• Exact size specs: shipped in a 4.5-foot tube; unfold to reach a 9-foot length for installation.
• Code‑ready and versatile: designed to meet national building codes for safe, durable installations on new builds and remodels.
• Air and moisture management: allows vapor to escape while limiting air infiltration in wall cavities.
• Translucent design: provides visibility during cutting, fitting, and fastening to reduce rework.

Benefits in practice

In typical projects, Prime Wrap supports a consistent and reliable wall barrier. The moisture protection helps minimize hidden dampness during wet seasons, while the air barrier reduces drafts around exposed areas. When paired with proper insulation, it contributes to a more efficient thermal envelope.

• Reduces temperature loads by limiting air transfer through framed walls, helping heating and cooling systems work more efficiently.
• Encourages moisture movement out of wall cavities, helping prevent condensation‑related issues and material degradation.

Designed for both residential and commercial applications, Prime Wrap PR-4575 offers a robust, easy‑to‑handle solution for protecting wall assemblies. The translucent film supports efficient jobsite workflows—from planning through cutting and securing—making it a practical option for sidewall installations.
