Modern Glass Technology by IQ Glass

Steel Framed Doors

The Mondrian External Series is a range of 'Crittall' style metal windows and doors designed to recreate the traditional steel effect framing used on industrial loft style buildings and art deco design.

IQ can create these elegant metal framed doors, with full thermal breaks, out of a range of materials to achieve the desired visual effect:

  • Galvanised Steel

  • Stainless Steel

  • Corten Steel

  • Architectural Bronze

With a surrounding frame of only 47mm the Mondrian External Doors recreate that slim framing effect and you have the option to include horizontal transoms throughout the door design as required to create the design aesthetic wanted.

Our Mondrian Windows product offers a window with a matching 'Crittall' style design.

Thermally Broken Steel Doors

The difference between Mondrian and other traditional 'Crittall' like steel doors is that the Mondrian External Doors are fully thermally broken and use high insulation double glazed units in order to ensure the thermal performance requirements of modern windows and doors.

Our slim framed metal doors have been fully weather tested for air permeability, water resistance, wind resistance and thermal performance.

The durable steel frame of the doors mean that you can design them into large opening sizes, double opening and also can be manufactured with arched heads to suit the arched doors of restoration projects.

For security a metal locking plate to suit the chosen framing material is included on any Mondrian External door which includes the lever/lever locking handle and key lock. The handles themselves come in a range of designs and finishes including burnished steel, chrome polished finish, polished brass and Corten.
