Fabric Storm Shield
Q: I live in an area that was hard hit by a couple of recent storms. I've heard that there is a fabriclike material that can be used to protect windows. It's supposed to be similar to what's found on trampolines. Can you provide further information?

A: Armor Screen, a company based in Riviera Beach, Fla., manufactures a fabric system to shield structures from hurricane damage (www.armorscreen.com). It is a flexible, woven polypropylene fabric designed to deflect wind-blown debris and driving rain, and to withstand extremely high wind pressures without rupture. The system is lighter and easier to deploy than steel or plywood panels. A homeowner unrolls it and attaches it to eye hooks and eyebolts that are installed in and around the home.
The Armor Screen system has been wind-pressure tested up to 195 pounds per square inch--the equivalent of 276 mph. That rating well exceeds peak winds associated with even Category 5 hurricanes (winds over 155 mph, on the Saffir-Simpson Hurricane Scale), such as the deadly Labor Day hurricane of 1935, Hurricane Camille in 1969 and Hurricane Mitch in 1998, all of which had peak wind speeds of about 180 mph. Armor Screen exceeds the requirements of Florida's building code and those of the storm-prone Miami-Dade area.
The screen is installed by contractors, and is not a do-it-yourself project. Armor Screen may cover the entire face of a building or shield vulnerable elements, such as windows and sliding doors. To diffuse the impact of windblown debris, the screen must be free to deflect, so it is anchored to the building and the ground with at least 22 in. of space between it and the structure. The amount of deflection space varies based on the height of the wall.
Armor Screen's cost depends on its size and on factors such as the type of anchors used and whether they are placed in wood, masonry or the ground. Generally, it costs $13 to $15 per square foot, and on rare occasions, up to $17 per square foot.
