ThePerfect Balance

of Moisture & Air Management

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

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.

All housewraps are not equal.

Residential & Commercial Housewrap

PATENTED CONSTRUC-TION Fortress Pro’s unique patented microporousconstruction provides the ultimate in strengthand durability for demanding applications.

• Microporous, reinforced breathable membrane withstands the demands of in-stallation for long-term protection againstwater and air penetration.

• Grid of high strength fiber reinforcement isbonded to a soft non-woven fabric for alightweight yet durable housewrap with ex-cellent staple and nail holding strength.

• Coated and Microflex® intermeshed, creating billions of mircopores. Pore sizesare smaller than a drop of water so rainwon’t penetrate, but larger than watervapor molecules so water vapor will es-

WATER HOLDOUT• Fortress Pro has one of the highest levels of

resistance to water penetration under hy-drostatic pressure of all the weather resis-tive barriers on the market today.

• Exceeds 900 cm of pressure per AATCC127-2003 (very critical if the product youchoose must function as the secondary lineof defense for water management).

REDUCED AIR INFILTRATION • Fortress Pro’s unique design delivers ex-

cellent resistance to the penetration of airthrough the outside walls.

• Provides continuous protection against en-ergy robbing air infiltration and wind wash-ing.

MOISTURE VAPOR PERMEABILITY• Water vapor permeance of 13 perms

provides the right balance of moisturemovement in the wall cavity.

• Allows damaging moisture to escape whilelimiting the inward movement of moistureinto the home.

EASY INSTALLATION • Fortress Pro is translucent, making it easy

to locate nail heads and sheathing seamsduring siding installation.

• Tough fiber reinforcement combined with ahigh strength non-woven fabric providessuperior tear resistance and durability withexcellent staple and nail holding strengthduring and after installation.

• Fabric structure makes it very quiet to workwith, eliminating the harsh noise of windwhip – often a complaint made by in-stallers.

DURABILITY• Fortress Pro contains a very effective sta-

bilization package to help protect it from UVrays and thermal degradation before andafter installation.

• Can be left exposed for up to 120 days priorto installation of the final finish.

• Backed by a 10 year limited warranty.
