The new FerroFinestra thermal barrier system W50 TB, carries on the window heritage in its most authentic form. It applies 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 combined with low emissivity glass up to 37 mm, allow to fully respond to current regulations and contemporary needs for comfort. Also it performs in harsher weather conditions, where windows made from solid steel profiles may not be sufficient. Explore the 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.
