Sonafold insulated industrial folding doors are designed for internal and external openings where a reduction in noise transmission is required, such as the turbine halls of power stations.

Manufacture

Door panels are made from hollow rolled steel sections with 2mm thick flat galvanised steel facing sheets on both sides. They are infilled with a high-density insulation material to an overall thickness of 64mm.

The robust, flat-faced construction makes them capable of withstanding severe wind conditions.

Installation

Top hung on four wheel bearing hangers that incorporate panel hinges and run in a galvanised top track. An auxiliary top track is attached to ensure the panels fold correctly.

Brass rollers connected to the bottom hinges run in a steel channel bottom track, which is set for alignment in a 200x100mm chase before final grouting into position.

Operation

Operated by a three-phase motor mounted on the top track with open / close / stop push buttons installed adjacent to the opening at the bunch side.

Disconnection is provided at low level at the motor side for manual operation in the event of an emergency and safety edges are fitted as standard to the leading edges.

Options

  • Wicket doors with a cylinder lock
  • Polyester powder coating in choice of standard colours
  • Control option
  • Safety photocells
