Exterior wall solutions from DuPont Performance Building Solutions provide a systematic approach that works for your entire building envelope. Innovative and easy to use, our exterior weatherization, insulation and sealant systems deliver unparalleled performance. 


Continuous exterior insulation 

Insulating the entire exterior wall span—not just the space between the wall and the studs—minimizes thermal bridging and maximizes energy efficiency. We offer a range of high-performance insulation products that provide:


• High, long-term R-value

• Exceptional moisture resistance

• Excellent compressive strength

• Long-lasting durability and performance
