Drexel Metals offers three new roof insulation products. Defend-R, a line of rigid roof insulation panels, features a closed-cell polyiso foam core manufactured on- and off-line to various facer types. The Defend-R CI line consists of rigid wall insulation panels that are also composed of a closed-cell polyiso foam core manufactured to various facers types in both standard and Class A variants. True to its commitment to extending sustainable building solutions of the highest quality and value to its customers, Drexel Metals’ newest product lines are manufactured using NexGen Chemistry to deliver energy-efficient performance to residential and commercial projects.
“From insulation that provides the highest R-value per inch to custom-finished metal to profile-specific clips and screws, Drexel Metals is offering project teams a comprehensive building system,” Todd Bergman, Product Manager at Carlisle Architectural Metals said. “We are able to offer a complete system approach to roof and wall assemblies because we are backed by Carlisle, whose years of experience in polyiso manufacturing and moisture and vapor barriers is invaluable. We’ve leveraged that product category experience to give our customers the highest quality insulation solutions for their next project.”
Drexel Metals’ three new roof insulation prodcuts include:
- Defend-R: a durable rigid roof insulation panel composed of a polyiso foam core manufactured on-line to fiber reinforced facers on each side (GRF). Approved for direct application to steel decks and compatible with all major roof covering systems.
- Defend-R Coated Glass: a rigid roof insulation panel composed of a polyiso foam core manufactured on-line to a premium performance coated glass facer on both sides (CGF).

- Defend-R Nail Base: a rigid roof insulation composite panel composed of a polyiso foam core manufactured on-line to a fiber-reinforced facer on one side and oriented strand board (OSB) or plywood fastening substrate on the other, providing a solid surface to attach standing seam metal panels, shingles, and slate tiles, as well as single-ply roof systems.
