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.

Valéron Vortec™ EVD™ (Engineer Vented Drain) is a crush resistant, weather resistive barrier designed to drain moisture away from the wall cavity in homes and commercial buildings. An engineered surface pattern of raised, micro-perforated dimples creates a crush resistant airspace between framing and cladding, allowing moisture to drain away from the wall cavity rather than pond behind the building façade.

Valéron Vortec™ EVD™ allows necessary moisture vapor migration while helping to protect against energy robbing air infiltration and the formation of mold and mildew that can lead to frame rot and poor indoor air quality. Valéron Vortec™ EVD™ is designed to drain and is intended for use behind a range of cladding systems including stucco, EIFS, masonry, cementitious cladding and weatherboard.
