A building’s exterior gets a lot of attention.
But it’s what’s beyond the surface - inside the building envelope - that truly impacts the comfort and energy efficiency of indoor environments.

Protect your building with the TYPAR® Weather Protection System.

How can you build a home that provides excellent comfort and energy-efficiency while controlling the damaging impact of moisture intrusion? The TYPAR Weather Protection System. It provides exceptional air and water holdout, optimal moisture vapor transmission, superior tear strength and outstanding surfactant resistance PLUS The TYPAR Advantage.

At the heart of the system are TYPAR Weather Resistant Barriers (WRB) which act as air and moisture barriers, while allowing moisture vapor to escape from the wall cavity. Installed before the exterior siding, TYPAR WRBs also protect the structure from Nature’s harshest elements with exceptional tear strength and ultraviolet stability.
