Summary
Providing thermal resistance of 1.8 w/m²K, the Bolton Gate Company Thermafold 2000, insulated folding door is ideally suited to the closure of openings where a reduction in thermal transmission is required.
The flat faced panel construction provides a robust, yet aesthetically pleasing appearance capable of withstanding high wind load conditions.

The top hung arrangement allows the Thermafold to be provided on openings up to 24m in width and can be supported by a wide array of operating controls and safety devices.
The energy saving option of an integrated wicket door can be incorporated allowing access to authorised personnel without the need to open the full door.
Operation
The doors are electrically operated as standard using a 400volt nominal, 3 phase direct drive motor mounted on the top track.
Emergency hand chain operation with low level engagement is provided with the motor.
A control panel with integrated open/close/stop push buttons is positioned adjacent to the opening at the bunch side.
A wireless safety edge is mounted to the front edge of the leading panel(s).

The standard arrangement is for the Thermafold 2000 to be face fixed internally but there is also the option of mounting between the jambs.
The doors can be single (bunching to one side) or bi-parting.
Panels
The panels are constructed from rolled steel hollow sections with 2mm thick flat galvanised steel facing sheets.
The panels are filled with a high density, acoustic dampening, insulation material and have an overall thickness of 64mm.
Hinges / Guide Pins
