NON-FIRE INSULATED SHUTTER

This design can incorporate a fail safe system whereby in the event of power disruption during fire, the shutter can still closed.

A delay timer can be used for escape purpose during emergencies. The timer will allows the shutter to stop at half level for a few seconds or minutes before closing fully.

When shutter motor is over 1000kg then the motor requirement will use a 415V, 3 phase power supply. 3 phase motors if required can be installed with additional cost as an option.

Our vertical side guide brush door seal and rubber weather seal allow our slats to roll up and down with flexibility. Our nylon brush are of high quality which will not wear out easily or dereriorate. The rubber weather seal are made of natural rubber that comes with air release holes for soft compression against the slats. It helps to completely seal both sides of the vertical guide. It also act as an air-blockage as well as serve the purpose of energy saving. Draughts, dust, heat, insects, cold air, noise, smoke, light and rain will not pass through that easily.

Vertical guides are contructed from mild steel plates formed to channel of 75mm X 90mm or 150 X 75 which are aligned to the shutter casing.
