Introducing a durable new water-resistant barrier unlike any other. Valéron Vortec™ with EVD Technology™ has a unique 3-dimensional engineered surface that allows for non-directional installation and drainage of water and moisture that happens to get past the exterior siding. Vortec is equivalent to other WRB's or housewraps, can be used behind all types of cladding, and is the first and only multi-directional drainage barrier.
