A sealed building envelope means improved energy efficiency

Sealing the building envelope using DuPont™ Weatherization Systems helps provide the superior durability needed in commercial construction. Our innovative systems are designed to integrate seamlessly to help seal the building envelope and provide protection from air and water infiltration. Individual products in the system are backed by a limited warranty from DuPont, which includes a documented job-site service package conducted by a DuPont™ Tyvek® Specialist. And DuPont™ Weatherization Systems can help contribute towards U.S. Green Building Council LEED® points, helping you seal the building envelope for improved energy efficiency and air quality. That means a more sustainable, durable structure that’ll operate efficiently for years to come.
