Construction Film & Sheeting - House Wrap

RESIDENTIAL • COMMERCIAL • STUCCO

For years, builders, contractors and architects nationwide have been using Raven residential and commercial housewrap to reduce air filtration and water penetration for increased energy savings, long-term durability and improved comfort. Now, we’ve developed Fortress Pro™ Weather Protective Barrier - the best housewrap your money can buy.

Fortress Pro™ Weather Protective Barrier was developed specifically to meet today’s demanding expectations for an energy-efficient and healthy living environment. Building science experts focus on two major functions of a breathable housewrap: They expect it to prevent airflow through the outside walls, and to stop and drain liquid water that has penetrated the exterior finish. The end result is a more maintenance-free structure reducing the risks of rot, mold and mildew while reducing air infiltration and lowering energy costs.

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.
  • 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).


REDUCED AIR INFILTRATION

  • Fortress Pro’s unique design delivers excellent resistance to the penetration of air through the outside walls.
  • Provides continuous protection against energy robbing air infiltration and wind washing.

MOISTURE VAPOR PERMEABILITY

  • Water vapor permeance of 13 perms provides the right balance of moisture movement in the wall cavity.
  • Allows damaging moisture to escape while limiting the inward movement of moisture into the home.


DURABILITY

  • Fortress Pro contains a very effective stabilization package to help protect it from UV rays and thermal degradation before and after installation.
  • Can be left exposed for up to 120 days prior to installation of the final finish.
  • Backed by a 10 year limited warranty.

EASY INSTALLATION

  • Fortress Pro is translucent, making it easy to locate nail heads and sheathing seams during siding installation.
  • 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.
  • Fabric structure makes it very quiet to work with, eliminating the harsh noise of wind whip – often a complaint made by installers.

PATENTED CONSTRUCTION

Fortress Pro’s unique patented microporous construction provides the ultimate in strength and durability for demanding applications.

  • Microporous, reinforced breathable membrane withstands the demands of installation for long-term protection against water and air penetration.
  • Grid of high strength fiber reinforcement is bonded to a soft non-woven fabric for a lightweight yet durable housewrap with excellent staple and nail holding strength.
  • Coated and Microflex® intermeshed, creating billions of mircopores. Pore sizes are smaller than a drop of water so rain won’t penetrate, but larger than water vapor molecules so water vapor will escape the wall cavity.
