Application

Suitable for the closure of internal or external openings where a reduction in noise transmission is required. They have been provided on many power stations worldwide, where they enhance the acoustic envelope of buildings such as turbine halls.

Description

Steel acoustic folding door. The flat-faced robust construction renders it capable of withstanding severe wind conditions.


Features and benefits:

  • Door panels: constructed from 2 mm-thick, double-skin steel sheets, infilled with high-density rockwool. The door panels are 54 mm thick and are flush in appearance.
  • Seals: high-quality ethylene propylene diene monomer (EPDM) seals are fitted in-between the panels and at the jambs. Brush seals are fitted at the top and bottom.
  • Top track: galvanized steel rolled section, forming a box-type track on which pulleys run, mounted on the top of the door panels. A branch track is incorporated to allow the door to stack correctly. Brass rollers connected to the bottom hinges run on a steel channel bottom track, which is set for alignment within a 200 x 75 mm chase, before finally being grouted into position.
  • Bottom track: a galvanized steel bottom track is recessed into the floor, and acts as a guide.
  • Door arrangements: pairs of panels make up each door or half door (between two and ten on each side). The door is face-fixed to the inside, and the panels stack at 90° to the opening when open.
  • Operation: electrical operation is via a three-phase geared motor, mounted on the top track at one or both ends. Push-button controls are provided at low level, and emergency manual operation is via hand chain, which is connected and disconnected at low level.
