Steel Framed Doors

The Mondrian® Slim Door range offers a selection of industrial style metal doors designed to create a traditional steel design to glazing with modern performance values.

The framing used for the Mondrian® Slim Doors is fully thermally broken and is available in a range of architectural metals in order to achieve your desired visual effect. These specialist metals include frames made from Galvanised Steel, Stainless Steel, Corten Steel and Architectural Bronze.

With a minimal surrounding framework you are able to achieve a vent and frame profile of as little as 47 mm. The Mondrian® Slim Doors are then able to recreate that slim framing effect in consonance with industrial loft style buildings and art deco design.

The Mondrian® Slim Windows range offers a matching window design with Art Deco style design.

Thermally Broken Steel Doors

The difference between Mondrian® Slim Doors and other industrial style steel doors is that the Mondrian® Slim Doors are fully thermally broken and use high insulation double glazed units. This ensures that we achieve the thermal performance requirements of modern building projects and protect internal surfaces from moisture damage (which can occur if you select a non-thermally broken frame).

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 Mondrian® Slim Doors means that you can design them into large opening sizes, double opening doors and doors within larger steel framed screens or walls. The beauty of steel also means that these doors 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® Slim 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.

Industrial Designed Doors

When it comes to specifying a thermally broken steel door we have many profile options to choose from. In most circumstances we would first recommend the use of the Mondrian CWS-65 Slim system. This offers a high level of performance with slim metal frames, perfectly in keeping with the expected design of these door installations. 

As well as offering an artisan steel design, the steel profiles offer a range of material choices, from galvanised steel to architectural bronze. For further specification information about this system please see our product data sheet at the bottom of this page or visit the Mondrian website. 


The Mondrian® Glazing Website

We have created a dedicated website for the Mondrian® Range to offer you all the technical and specification information that you need. The website offers a full selection of the thermally broken Mondrian® systems as well as the non-thermally broken options for internal use.
