square-edged wood-aluminium system
Our TF 68 Duo K window system has a 68 mm profile thickness and a powder-coated, square-edged aluminium frame covering the wooden sections. Unlike many other systems on the market, Sorpetaler wood-aluminium windows have welded corner joints. All corner regions have a smooth surface without sharp edges. Glass thicknesses up to 40 mm can be used with this system, which means that windows can optionally be fitted with double or triple glazing.
