Insulated Roller Shutter Doors

Application

The shutter curtain is constructed from suitable interlocking, twin skin, galvanised steel laths, infilled 2 with polystyrene to give a ‘U’ value of 0.7W/m K and running in galvanised steel side channels, mounted on mild steel support angles, which are bolted to the structure.

	The curtain weight is counter balanced by helical wound springs, fitted inside a suitable steel tube barrel assembly at high level, running on steel bearings. The barrel assembly is supported between mild steel endplates and driven through gears.
A rubber seal is provided to the bottom edge of the door and a nylon brush seal to the door head. All mild steel components are finished in one coat of black primer.

Operation

Manual operation by means of continuous galvanised haul chain, through single or double reduction gearing.

Electrical operation is by means of a high quality, 3 phase motor and gearbox, incorporating 6 integral limits. All controls are low voltage and have open,close and emergency stop buttons as standard. Emergency manual override is provided as standard, to allow operation of the door in case of power failure.
