Why Hurricane Categories Make a Difference
During a hurricane you usually hear meteorologists refer to its intensity by categories. If you don't know the difference between a category 1 and a category 5 hurricane, The Weather Channel meteorologist Mark Elliot breaks it down for you.
Polycarbonate Window Impact Testing 001
In this video: we have tested the strength and durability of 3 different materials that are used in a variety of vehicles, By dropping a projectile onto the material and viewing the result. The Projectile in Question is a 2287g Steel Ball That has been dropped from a height of 4 metres. This is comparable to an average Branch (off a tree) hitting a Car at 40mph. The Testing Rig Is Property of SABIC Innovative Plastics. The Video is Property of Pastics4Performance.co.uk (Future videos will have sound/music, i didnt have time on this one!)

This Old House - Window Protection
http://www.heritageins.net When a hurricane comes to the Gulf Coast, what will you use to protect your windows? There are different classes of window protection. In this video, a cannon that shoots wood 2 x 4 (two by fours) into windows at 34 mph. The test windows are protected with 5 qualities of window protection: plywood, particle board OSB, ballistic nylon treated with resins held with brackets, metal shutters, and impact glass. Plywood is 5/8 inch thick and costs $30 per sheet. It protects the house better than other common alternatives. Particle Board OSB is 1/2 inch thick costs $10 per sheet but only provides minimum protection. Ballistic Nylon Sheet prevents objects from entering your home, but doesn't protect the glass of the window. Metal Shutters may end up with the metal shutter AND the window broken The Impact Glass Window is insulated and will shatter like a car window but you won't get a hole in it (and your house is still protected from wind and rain). In the insurance business, this is the only grade of glass that's considered good enough for the customer to get a discounted price on the overall premium.

How to Choose Hurricane Window Protection | Ask This Old House
General contractor Tom Silva shows a homeowner several ways to protect windows during a storm. (See below for steps.) SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Steps for How to Choose Hurricane Window Protection: 1. A layer of 5/8-inch-thick plywood can protect windows from a 2x4 traveling at 34 miles per hour. An identical layer of oriented-strand board (OSB) can't. 2. Covering windows with resin-treated ballistic nylon will prevent the 2x4 from shooting into the house, but it won't keep the window from breaking. 3. Metal storm shutters are permanently mounted to the house. If struck in the right place, the shutters can bend inward and crack the window. 4. A window with impact-resistant glass will shatter when struck, but the window won't break apart or crack open.

Impact testing - Fabric is stronger than metal.
We use our cannon to test how well a variety of structures can withstand projectiles moving at hurricane wind speeds. Flexible hurricane screens / fabric hurricane shutters like the ones designed by our company can stop projectiles more efficiently than hard rigid structures, which will shatter under-force. Screens are also more reliable in protecting openings even when damaged, as loss of protection is localized to the damaged part of the screen. Custom Hurricane Products Inc. has the only hurricane shutter on market to withstand the rigorous FEMA 361 hurricane testing protocols. http://www.ezmaxfl.com
