WHAT DOES THERMALLY BROKEN MEAN?
While the name itself has a negative connotation to it, the concept is very positive when it comes to metal windows and doors.
In layperson’s terms, thermally broken refers to high-performance insulator material separating two metal halves, whether aluminum, steel, or bronze. The insulator cuts down the ‘thermal bridging.’ With NON thermally-broken systems, or solid metal systems, cold and heat can exit or enter the interior of the home by traveling or “bridging” through the solid metal perimeter frame or true divided muntins.
WHY USE W-20 & W-40 STEEL?
W-20 Swiss Steel…
A strong point of steel is the ability to be curved into any shape or geometric form and then to be transformed into a window. For extremely slender requirements, the W20 range offers as well a slim casement line, which allows to further lighten the visual impact of the frames.
W-40 Swiss Steel…
The strong point is the increased profile depth, which allows to accommodate double glazing up to a thickness of 27mm. The W40 is not only used in the field of restoration, but it’s also highly acclaimed in contemporary architecture for its elegant and compact sightlines, ensuring safety and comfort thanks to its excellent thermal and acoustic performance.
