unico xs
The Forster unico xs is the most filigree and highly insulated steel window system in the Forster range. Its extremely slender face widths create an almost invisible frame, maximizing the glass area and light transmission. Despite its delicate appearance, the unico xs is engineered for exceptional performance — achieving thermal values down to 0.9 W/(m²·K), RC3 security certification, and even FB4 bullet resistance where required. The system accommodates leaf sizes up to 2378mm and is available in flush and recessed configurations, making it the ultimate choice for architects seeking the thinnest possible steel profiles without compromising performance.
