Panels

Kingspan 610mm x 40mm thick FireSafe composite panels manufactured using 0.5mm thick hot dipped zinc coated (to BS EN 10147) steel internal and external facing sheets, each with a class 1 surface spread of flame when tested to BS 476: Part 7:1971. These sheets are bonded together using IPU foam, which has a density of 40ks/m3. The panel itself gives a “U” value 0.51 W/m2 K, meaning that typical 5,000 x 5,000 wide door has a “U” value of 0.9 W/m2 K and has formed tounge and grooved hinged joint, incorporating a neoprene seal running the full length of the panel to give excellent weather resistance. 80mm panel also available has a typical “U” value of 0.24 W/m2 K, meaning that a typical 5,000 x 5,000 wide door has a “U” value of 0.54 W/m2 K. The acoustic value of the door panel has a single weighted sound reduction of [RW] of 25db. Standard stucco finish is embossed primer coated to both faces.

Door Head Gear

Sectional doors are counterbalanced to ensure the smooth running of doors. Using minimal effort. All counterbalance spring calculations carried out by Indupart are designed to get the maximum life out of the door springs we manufacture (most typical loading docks are calculated to a minimum of 20,000 cycles). The springs are high tensile helical wound steel. Shot blasted for improved performance. The springs are mounted on a steel shaft supported by bearing brackets incorporating sealed bearing rollers, to ensure free running of the shaft. Also mounted on the spring shaft are the cable drums. These carry the aircraft quality cables, which have 7:1 safety factor. These are looped and swaged using a hydraulic press to ensure the cables do not get detached from the cable drums or the brackets which connect the cables to the bottom of the door panels. Spring break devices and cable breaks are fitted to doors as standard to comply with CE markings.

Panel Options

Kingspan Plastisol XL200 or polyester coating to the external face an extensive range of colours. Internal RAL 9010. Factory paint finish to either internal or external face to any BS or RAL colour.

Panel Hardware

The roller carriers are adjustable and along with the intermediate panel hinges, are hot dipped galvanized steel. The rollers which run in the side track are sealed for life, self-lubricating bearings c/w a nylon tyre to give smooth and quiet operation and sealed directly to the seal connected to the side fixing angle. This is also pre drilled.

Guide Tracks

The door tracks are galvanized steel ‘J’ type (designed to give free and easy running for bearing rollers). These are mounted on a galvanized steel jamb angle for fixing purposes via Indupart’s unique stud welding system which ensures the most effective seal to the building as the tracks need no adjustment on site. Cable break devices are fitted to all doors to comply with CE markings, we also offer a optional anti lift bracket.

Guide track options

Guide tracks are individually manufactured to suit site conditions, taking into consideration door size, headroom and roof pitch, see ‘installation clearance’s’ section for details.

Seals

All Indupart sectional doors are fully perimeter sealed, as well as the intermediate panel seals, to provide the most effective weather seal to your door. All fixing faces, floors and lintels must be flush and square.
