FerroFinestra W50 TB

With the new Ferro Finestra thermal barrier system W50 TB, Extend House carries on the window heritage in its most authentic form, proposing the same forms, proportions and overlapping effects of the original 20th Century hot rolled steel window profiles, refined by cold rolling technology. The innovative high-density polyurethane isolator used as thermal barrier, together with the possibility of housing low emissivity glass up to 37 mm, allow to fully respond to current regulations and contemporary needs for comfort, also in harsher weather conditions, where windows made from solid steel profiles may not be sufficient. The range is completed by a wide range of exclusive fittings in several finishes, reproduced from original designs of the modern era. Any kind of inward or outward openings are possible.

The new FerroFinestra W75 TB system keeps the streamlined and clean design of the FerroFinestra family while offering superior thermal insulation. It features flush and overlapping aesthetics, an efficient polyamide insulating core, and a profile design that accommodates the latest selective insulating glass. The W75 TB system responds to the most demanding projects, for all types of windows and doors where the highest aesthetic and performance requirements are expected.
