PAC-Shield CV OSB
PAC-Shield CV
Roofing InsulationPAC-Shield CV is a ventilated composite insulation panel designed to optimize roof performance. Its built-in air gap and high-efficiency insulation help control heat transfer, reduce ice dams, and improve indoor air quality—making it ideal for steep-slope applications using metal, slate, tile or shingle roof systems.

Overview
PAC-Shield CV is a composite insulation panel that combines high thermal performance with built-in roof ventilation. It features a 4×8-ft. layer of closed-cell rigid polyisocyanurate (ISO), integrated solid wood spacers that create a consistent 1-inch air gap, and a top layer of APA/TECO-rated OSB or plywood for secure nailing and support.
Designed for use with metal roofing, slate, tile, and shingles, PAC-Shield CV improves energy efficiency by reducing heat transfer through the roof. It delivers R-values ranging from R-5.7 to R-20.5 for strong thermal resistance, helping to reduce energy consumption and costs year-round. The ventilated design promotes airflow beneath the roof system, minimizing temperature fluctuations that can lead to ice dams and issues like oil canning.
PAC-Shield CV is manufactured using eco-friendly NexGen Chemistry, with no CFCs, HCFCs or HFCs, and zero ozone depletion potential. It supports healthy indoor air quality by reducing trapped moisture and meets key building code requirements and standards, including ASTM C1289 and the International Building Code (IBC).
Ideal for steep-slope applications of 3:12 or greater, PAC-Shield CV enhances both performance and sustainability in ventilated roof assemblies. For lower-slope installations, a non-vented nailable polyiso panel is recommended.
Advantages of using the PAC-Shield CV venting system include:
Applications
PAC-Shield CV is custom built to incorporate the individual specifications of the building designer. PAC-Shield CV is for use on slopes of 3:12 or greater (for lower slope considerations see PAC-Shield Nail Base).
Applicable construction types include:
