Weathering the Storm
Manufacturers Respond to Hurricanes with More Resistant Products

Door and window manufacturers are working on more ways to keep homeowners from having to board up their windows when the big storms strike. New hurricane-resistant sealants, door and window components and finished products are being introduced as this year’s hurricane season hits its fierce peak. 

COMPONENTS

Flood Barrier Shields Doors
Zero International of Bronx, N.Y., is offering a flood barrier shield for doors. The company says the product is simple to install and remove, and the barrier helps protect doors from water ingress in flood prone areas. The key to the shield’s impermeability is the use of closed cell neoprene rubber that lines the channel brackets and the bottom of each shield section, according to information from the company.

It is available in sections to make 10- and 20-inch-high barriers. The aluminum shield requires no tools to install into pre-mounted vertical channels. The unit complies with FEMA and FIA regulations, for use on doors. 

MI Adds Aluminum Frames to StormArmor Line 
MI Windows and Doors of Gratz, Pa., has added aluminum frames to its StormArmor line. The windows are available in a full line of operable, fixed and architectural shaped units in multiple color options. 

StormArmor windows are designed to resist impact from wind-borne debris and are an attractive alternative to shutters. StormArmor draws its strength from a PVB interlayer. Even when struck with flying debris, the product is designed to stay in one piece, sealing out high winds and reduce further damage. According to information from the company, StormArmor products meet building codes for hurricane prone states including Florida.

Wall of Wind Aims to Study Window Performance

A project proposed by professors at Florida International University (FIU) and the University of Florida for the Florida Building Commission aims to create a new testing apparatus, the Wall of Wind, to reproduce the actual dynamics of wind and rain on a low-rise structure at full scale. The Wall of Wind is currently under development at FIU. 

The impetus for this project comes from the fact that improving buildings located in hurricane-prone regions can reduce loss and damage significantly. In fact, according to the report, the State of Florida contracted local universities to conduct damage assessments of homes built to the 1994-2002 Standard Building Code (SBC) and to the Florida Building Code 2001 that went into effect in July 2002. Preliminary results indicate the insured losses for the FBC homes are 40-50 percent lower than equivalent homes built to the SBC. 

Members of the fenestration industry see the value of this type of research and have lent their support. Andersen Corporation will provide glazing and fenestration for the wall and the American Architectural Manufacturers Association serves as a co-sponsor.
 
In the project, the wind/rain field will travel 10-16 feet from the exit of the Wall of Wind to the test subject—such as a corner or a part of a full-size single-story house—where high-speed cameras will monitor its degradation. 

One of the objectives of the program is to model water infiltration through drained/mass wall assemblies and building subsystems which includes doors and windows. Research will evaluate Clause 5 of the AAMA/WDMA/CSA 101 I.S.2/A440-05 which specifies that the minimum water penetration resistance test pressure shall be 15 percent of the design pressure for family dwellings. Additionally, the performance of window systems impacted by wind-borne debris and wind buffeting will be targeted to evaluate the pressure cycle requirements with regard to design reliability and impact momentum required for glass breakage. 

The Wall of Wind project will also study ASTM, AAMA and the WDMA test methods that evaluate the performance of doors and windows. 

According to Forrest James Masters, PhD at FIU, researchers are studying water intrusion on soffits presently and fabricating the first module of the RenRe Wall of Wind (six fans). There is no a target completion date, yet, as Masters says he, and others working on the project, are still working with large sponsors to get the larger facility operational.
