Product Options | Hatch box/ trapdoor: - Size (l x w):
- Material: Steel: 1.5 mm-thick with a steel trapdoor. The trapdoor is constructed from two layers of 1.5 mm-thick sheet steel infilled with 38 mm of mineral wool to give a 30 minutes fire resistance or 75 mm of mineral wool to give 60 or 90 minutes fire resistance. There is a 29 mm wide lip to the bottom of the lining around the external edge, which is designed to butt up against the ceiling to help prevent flame and smoke ingress. Similarly, there is also a lip to the bottom of the steel trapdoor, which extends to within 15 mm of the lip on the lining. Wooden: Hatch box is constructed from 18 mm thick laminated wood. Insulated trapdoor: An insulated 62 mm thick sandwich trapdoor which is white coated to the underside. The insulation U-value is 0.58 W/m²K. The trapdoor is also airtight to DIN 4570, class 4 and the hatch box has a rubber seal all the way around. White coated mitre cut strips are provided ready to be pinned on the underside of the hatch box. Treads: Treads between 200–380 mm wide are 140 mm deep, treads between 430–560 mm are 160 mm deep. Tread width is dependent upon hatch box width and floor-to-ceiling height. Operation: - Electrical: Electrically operated stairway runs on 24 V DC. and is fully supplied with wiring, standby battery, transformer and operating switch. It is also possible to fit a further switch thereby allowing operation from above. Options can also include a lock switch, visual and audible warnings and smoke warning. - Manual: Counter balance spring operation. Top operation: Allows the stairway to be raised and lowered from above and below. The maximum floor to ceiling height would be 4300 mm, or 4600 mm subject to confirmation. A top-operation handle can be fitted for hatch box depths of 200 mm to 390 mm, with at least 700 mm of clear space behind one end of the hatch box to allow the handle to rotate. For deeper hatch boxes, or where there is no space behind the hatch box, the Supreme can be fitted with a boden cable release system and a second operating pole for use from above. |
