Dupont Rigid Foam Insulation replaces non-insulating above-grade sheathing products like plywood, fiberboard and OSB, and eliminates the need for additional air barriers such as housewrap. It has clear film facings on both sides for added durability.

Styrofoam Boards are also designed for insulating interior basement walls, crawl spaces, and ceilings in both renovation and retrofit situations with precut insulation sheets and slotted edges that accommodate wood nailing strips that serve as a nailing base for drywall.

Living up to today’s demands for energy efficiency is about meeting or exceeding modern energy codes. DuPont building envelope solutions are designed to control air flow, eliminate leaks, and provide your building with the resilience to contend with the forces of nature.

Products such as DuPont™ FlexWrap™ EZ and LiquidArmor™ Flashing and Sealant improve the weather resistive barrier in your building, providing air and water holdout.
