DuPont Safety & Construction has released DuPont Tyvek DrainVent Rainscreen to provide advanced protection against moisture damage in exterior wall systems. The product creates a 6 mm space for water drainage and air movement for drying behind cladding, and can be installed behind stucco, stone veneer, brick, wood, fiber cement and metal panel systems. It helps to prolong the life of exterior cladding by creating a gap that helps prevent rot, cracking and peeling problems.
The product replaces the intervening layer required with stucco and stone, while the attached heavy-duty filter fabric prevents mortar and stucco infiltration. Tyvek DrainVent is easy to cut and install, lays flat and rolls tight against corners, helping protect against poor installation and detailing errors. The heavy-duty filter fabric keeps mortar out, helps create a flat surface to allow the cladding to lay flat and has a high-perm rating so it is very breathable; it also provides uniform nonstructural support for the various claddings.
