Our thermally broken slim line steel windows are ideal for: Le Corbusier’s strip windows, Bauhaus-style glazing, listed buildings, and lofts. Our Slimline windows are based on Janisol Arte design. The profiles have face widths of only 25 or 40 mm. Selected materials, such as steel and glass fibre-reinforced high performance plastics, guarantee minimal heat loss and maximum stability. DG units can be easily integrated into the profiles with a basic depth of 60 mm. Available opening types: inward or outward-opening, side-hung, bottom-hung, and top-hung.
