A revolutionary development in moisture management
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.
A housewrap that promotes drainage
Valéron Vortec promotes drainage with a unique crush-resistant pattern that creates an
airspace to reduce the solar-driven inward vapor drive. Valéron Vortec helps protect homes
from potential mold growth and eventual rotting of wall frame members.
What Makes It Better?
- Imparts a stand-off property between sheathing and siding.
- Allows moisture to drain rather than pond along the siding edge.
- Reduces potential for mold growth and frame rot.
- Non-directional channels allow for faster non-directional application.
- Lightweight rolls offer easy installation.
- The benefits of a rainscreen combined with a weather resistive barrier.
- Translucent material for ease in finding studs, edges and openings.
- Available in industry standard 60” widths for 1000 sq. ft. of coverage.
