Two recently introduced products from steel system specialist, Schueco Jansen, mean that architects and designers working at the high end of the residential market now have real choice when it comes to specifying top-of-the-range glazed sliding-door installations, according to windows, doors and façade company Schueco.<br> <br> This is because in addition to slim profiles, narrow sight-lines and excellent insulation values, the Janisol Lift-and-Slide Door and the Janisol Folding Wall have the rigidity and structural strength of a steel construction, the company claims. The result, it says, is two stylish doors combining premium quality with robust practicality and large glazed areas with maximum levels of security.<br> <br> Both door systems are manufactured from thermally insulated steel profiles and benefit from a strong, all-welded construction with no visible mitred or butt joints, Schueco says. Similarly, both systems are able to accommodate large openings with leaf sizes up to 1.0 m x 3.2 m for the Folding Wall and 4.27 m x 3.2 m for the Lift-and-Slide Door. <br> <br> www.schueco.com
