Putty glazed steel windows

There is no exact date of when these arrow shaped profiles were first rolled, but they date back to a period between 1890 and 1905. The name “Stucco” comes from the putty or filler used to fix the single glass in this type of windows. This gave the window an arrow effect on the inside and outside. The system was composed mainly of four hot-rolled profiles and some complementary profiles hot rolled and bent from sheet metal. The typical frames made with these profiles were for large industrial sidewall windows with horizontal pivoting openings.


Although all four original hot rolled profiles are still available, today this type of window is seldom used for outdoor applications due to its moderate coefficients of thermal insulation and water tightness. Nevertheless, thanks to its historic charm this line is often requested in areas of interior architecture. Alternatively to the putty filler a more contemporary sloped aluminum glazing bead can be used.
