W50 TB

The original steel windows of the 30’s thermally insulated


With the new FerroFinestra® thermal barrier system W50 TB, OTTOSTUMM 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, now refined and evolved thanks to modern technologies. The innovative high density polyurethane isolator used as thermal barrier, together with the possibility of housing high performance double pane glass up to 37 mm, allow to fully respond to current regulations and contemporary needs for comfort, also in harsher weather conditions, where the traditional steel windows may not be sufficient. Availability of a wide range of exclusive fittings in several finishes, reproduced from original designs of the modern era. Any kind of inward or outward openings: side-hung, double-vent (French style), bottom-hung, top-hung or projected top-hung, horizontally and vertically pivoted windows, as well as large sliding and folding doors.

W50 TB

The somatic marker of this classic suite is the “stepped” design of the flanges. This detail confers windows nice proportions and shadow lines and allows to achieve a glass pane planarity between fixed and operable windows.

W50 TB basic

The great versatility of this series allows designing a different window style without the classic “stepped leg”. With the combination of few basic profiles, windows with reduced frame dimensions can be created, recalling a minimalist design.
