Glass Divided Lites
A lite refers to each separately framed piece of glass on a window or door. A mullion is the line that forms a division in a window or door and this division can either be a real, or simulated.
True Divided Lites(TDL): the glass on the window isn't a single piece, but multiple pieces separated by mullions that go through the glass.
Simulated Divided Lites (SDL): the glass is a large, single piece with mullions placed on top of the glass, but they don’t cut through it.
FerroFinestra W75 TB
Ottostumm proudly presents its most recent innovation, the FerroFinestra W75 TB system. Distinguished by its sleek profiles and noticeable tactile texture, the W75 TB system represents the zenith of technological progress within our collection of thermally insulated steel and glass systems. Featuring a generous profile depth of 75 mm, this system is adept at accommodating highly energy-efficient insulating glazing, reaching an impressive thickness of up to 52 mm. The inclusion of a fiberglass-reinforced polyamide insulator bestows upon it exceptional thermal insulation qualities, making it the ideal choice for projects situated in regions with stringent energy-saving regulations and challenging climatic conditions.
FerroFinestra W50 TB
Introducing the FerroFinestra Thermal Barrier System W50 TB, OTTOSTUMM proudly carries forward the legacy of windows in their most authentic form. This system presents the same shapes, proportions, and distinctive overlapping aesthetics reminiscent of the original 20th-century hot rolled steel window profiles, now refined through cold rolling technology.The key innovation lies in the use of a high-density polyurethane isolator as a thermal barrier, allowing for the accommodation of low emissivity glass panels up to 37 mm thick. This design not only ensures compliance with current regulations but also caters to contemporary comfort requirements, even in harsh weather conditions where traditional solid steel profiles may fall short.
