Thermally broken steel options available

What is thermally broken = Thermally Broken is a term which relates to the window or door frame, which is equally as important, if not more than the glass. The frame of a window has a significant impact on the overall energy efficiency of any window and door – including that of double glazed systems.

Our MF ISO -FINELINE features an advanced high-density insulated steel profile as a thermal barrier. This, together with housing high performance double or triple krypton filled glazing up to 37mm wide, ensures the system surpasses the requirements of current regulations while at the same time providing high levels of comfort, particularly in harsher weather conditions where traditional steel windows may not have previously been sufficient.

Metalform steel windows are hot-dip and galvanised. They are available in a choice of highly durable powder paint colours. The paint is baked on at high temperature to give an excellent finish.

While we offer any colour most of our customers go for black 9005 – maybe it’s too hard to choose.


Internal solutions are powder coated.

External solutions are hot dip galvanized to EN ISO BS 1461 and available in a choice of highly durable Akzo Nobel powder paint colours. The paint is baked on at a high temperature to give a superb finish. We recommend a range of classic colours (illustrated below) that in our experience look wonderful and retain their appeal over time. A wide range of non-standard colours are also available to order. We are able to offer a dual colour finish, where the window frame is painted one colour externally and a different colour internally.

The slim and multi-functional MF RP-curtain wall fire profile systems, with mullion-transom construction, together with their specially tested fireproof glazing, have a proven suitability for a range of fire retardation times up to 120 minutes. The structures can equally well be used for constructions over several stories, for curtain walls or as separating structures. 

Through their narrow face widths of 45 to 60 mm, slim and transparent architectural requirements can be fulfilled, and this in combination with meeting high static requirements. 

The fire protection characteristics are achieved by this construction alone, through the selection of filling elements and accessory components, without the need for additional measures. Different depths of building profile, from 45 to 180 mm, allow the greatest possible design variation. Fundamental corrosion protection is guaran- teed through complete (inside/ outside) pre-galvanizing.
A tested and proven sealing system with overlapping transom seals where they meet the mullions, guarantees a solution with a high degree of tightness for the internal seals and for the external glazing, giving an altogether high system tight- ness for external applications.
