DensGlass Exterior Sheathing Helps Wellbilt …

1 Date:April 2009 DensGlass Exterior Sheathing HelpsWellbilt International s Sure-Board ExteriorCladding System Pass Strict Miami-DadeCounty High Velocity Hurricane TestsThe ability to withstand the destructive winds and the impactof various objects during a hurricane in a coastal area is keyto the survival of any Exterior cladding system. DensGlass Exterior Sheathing from Georgia-Pacific GypsumhelpsWellbilt International s Sure-Board Exterior cladding systempass the strict Miami-Dade County and Florida Building Coderequirements for High Velocity Hurricane Zones (HVHZ).The system was tested independently to determine theperformance against specific criteria for impact resistance, airand water infiltration resistance and wind load Notice of Acceptance (NOA) for Exterior cladding systemWellbilt International received the NOA from Miami-Dade sBuilding Code Compliance Office (BCCO) confirming thattheirindependent testing was accepted for the Sure-Boardexteriorwall system, which utilizes either1 2 or5 8 DensGlass Exterior Sheathing as part of the system.

2 Thewall system received a rating for Large and Small MissileImpact and met structural load and cyclic pressure Sheathing has fiberglass mats on frontand back, rather than paper facings, and its versatilityallows it to be used as a substrate behind ExteriorInsulation and Finishing Systems (EIFS), stucco, brick andother cladding tests conducted included Florida Building CodeTesting Application Standards: TAS 201-Large and Small Missile Test Standards TAS 202-Uniform Structural Load Standards TAS 203-Uniform Cyclic Pressure Test StandardsIndependently, DensGlass Exterior Sheathing was recentlytested in accordance with ASTM E 330 by Hurricane TestLaboratory and surpassed existing wind load values.

3 Thetest evaluates the structural performance of Exterior build-ing materials under uniform static air pressure difference,using a test indicates that the product can now withstand windsin excess of 155 mph a Category 5 Hurricane wheninstalled horizontally with the proper framing support,screws and spacing. These improved wind load values areneeded for today s harsh environmental requirements forcoastal regions and throughout the where storms andother conditions can be equally fact, coastal communities from Delaware to Texas nowutilize the high standards of Miami-Dade County and theFlorida Building Code requirements for High VelocityHurricane Zones, even though their own communitieshave not written the standards into their local fiberglass mats that make DensGlass Exterior Sheathingmoisture and mold resistant penetrate into the panel continued on backGalvanized steel studs (20 gauge)
