Fortress Pro Weather Protective Barrier is the perfect balance of moisture and air management for residential, commercial and stucco use. Today energy-efficient healthy environments are a must. Building science experts recognize a houswrap must prevent airflow through the outside walls, as well as stop and drain liquid water that has penetrated the exterior finish. This culminates in a more maintenance free structure reducing the risks of mold, mildew and rot while reducing air infiltration and lowering energy costs.
Fortress Pro is easy to install! Its tranlucent nature makes it easy to locate nail heads and sheathing seams during siding installation. The tough fiber reinforcement combined with a high strength non-woven fabric provides superior tear resistance and durability with excellent staple and nail holding strength during and after installation. Your installers will appreciate how quiet it is to work with. The fabric structure eliminates the harsh noise of wind whip.

Water Holdout:
- Fortress Pro has one of the highest levels of resistance to water penetration under hydrostatic pressure of all the weather resistive barriers on the market today.
- Fortress Pro Exceeds 900 cm of pressure per AATCC 127-2003 (very critical if the product you choose must function as the secondary line of defense for water management).
MOISTURE VAPOR PERMEABILITY
- Fortress Pro's water vapor permeance of 13 perms provides the right balance of moisture movement in the wall cavity.
- Fortress Pro allows damaging moisture to escape while limiting the inward movement of moisture into the home.
REDUCED AIR INFILTRATION
- Fortress Pro provides continuous protection against energy robbing air infiltration and wind washing.
- Fortress Pro’s unique design delivers excellent resistance to the penetration of air through the outside walls
DURABILITY
- Backed by a 10 year limited warranty, Fortress Pro contains a very effective stabilization package to help protect it from UV rays and thermal degradation before and after installation.
