The level of demand is high for Hart’s Typhoon roller shutter doors brand, where it is being used in exposed areas as diverse as on the Highlands and Islands of Scotland. In Hong Kong, the Typhoon is on Data Centre high rise buildings and the airport.

With a high - performance specification, Hart designed and tested, verified by third party, a roller shutter at much higher levels of wind resistance than the classic maximum BSEN12424:2000 class 5.

We tested an 8M wide door to 5000 pascals and therefor claim 4000 pascals plus 25% safety factor. For comparison class 5 requires 1250 pascals which includes 25% safety factor says Nick Hart, Hart’s M.D.

Using wind speed is only an indicator, says Mr Hart, and does not reliably indicate what will happen in the real world. The force transmitted at a given wind velocity is not a reliable measure of the resultant pressure upon a door and of how it will affect the door as the density of air varies, the topography, height above sea level and adjacent structures can all hugely vary the force applied to a given door.

Additional benefits can be using stainless steel in saline conditions and the door can have security rating up to SR3, at the moment.

Mr Hart adds: “Areas where the Typhoon is the perfect solution includes restriction access, assisting with insurance compliance and in general reducing crime risk. With over 75 years of experience in industrial roller shutter doors, we have used our extensive engineering knowledge to design the Typhoon storm shutter. In summary the Typhoon is strong and long-lasting.

Hart Door Systems high-performance Typhoon storm shutters, designed and manufactured in the UK, are a wind-resistant, robust, electrically-operated roller shutter. This industrial roller shutter is perfect for high security in areas exposed to extreme winds from tropical storms such as Hurricanes, Typhoons and Cyclones.

This high security storm shutter is designed to comply with the current British and EEC safety regulations. Optional specification levels can be varied to meet any special operational requirements.
