Hart’s Typhoon shutter is the product of the moment says Hart’s chairman Doug Hart. It delivers groundbreaking wind resistance in windy environments where the inherent weakness of relatively light weight wind class 5 roller shutters is not good enough.
Early examples of World-class, Hart installations are in Hong Kong for the airport terminal doors and data centres with access doors going up to 20 stories installed over the last few years. In the UK, current contracts in construction include the Highlands and Islands of Scotland where significantly enhanced shutter design is being used to secure building and their access.
Tested and third party verified to a level which is up to four times the BSEN Class 5 wind resistance requirements, the shutter is currently available up to eight metres in width.
Hart’s Typhoon roller shutter range has been tested in a vertical plane, as a fully operational door with door operation cycle testing after the specimen was fully load tested. Wind speed alone does not translate to the pressure applied to a door / surface. The real pressure evaluation must consider the density of the air that is applied to a door along with a number of other factors.
Reported wind speed is a generalisation and the actual pressure applied to a door or any surface could be a factor increase over reported wind speed. The actual pressure can be magnified by topography, whereby its funnelled between structures or hills, height above sea level and finally a sucking or negative component when other doors are opened within a building to name a few.
When considering the design the exposure at the actual location is crucial. A factor should be allowed to compensate for wind buffeting and material fatigue when specifying the pressure load. The only real way to cater for all eventualities is to build a unique software model taking all factors into consideration, however this can be an expensive approach so careful consideration of the location and design by wind experienced specialists can be the most practical solution when looking at existing buildings.
Roller shutters are a brilliantly convenient way to close off an opening securely while utilising the least additional space for operational requirements.
Last century roller doors were made from wood but now shutters are very advanced and are now available in steel, stainless steel, or aluminium insulated or non-insulated and prefinished to a required colour.
Full automation, linked to robotic and other mobile equipment, high speed performance, high security, fire control, the options are endless with greater efficiency and first-class safety and operational capability.
Experience and considered design has resulted in the development of the Hart’s Typhoon shutter.
