Thermally Broken Steel Doors



Better insulate your buildings against heat loss with our Thermally Broken Steel Doorsets. The inclusion of a thermal break in these sleek security doors confers increased insulative abilities above those of the standard Glazed Door. This translates into warmer interiors, more comfortable working environments, improved soundproofing, and reduced heating and utilities costs. This door is ideal for street-facing offices and multi-occupancy premises with foyers and lobbies.

Every door is custom made to suit existing structural openings. They are designed on a CAD/CAM system and manufactured with CNC punching and pressing facilities to guarantee quality and long product life, so you can depend on it to secure your premises as intended.

Starting from: £499 + VAT

Optional Features

  • Fire rated FD30, FD120

Thermally Broken Steel Door Features

A thermal break runs through every doorset, insulating heat, reducing the spread of cold from outside, and minimising sound for warmer, quieter working environments.
The security of the door remains unaffected, reinforcing the exterior of your buildings against damage and unauthorised entry.
You have the option to customise your door, giving you complete control over its size, shape, and appearance.
Every door can also be installed in your building by our in-house team, ensuring an expert fit.
