Slender profile sight lines with even the largest of building components – this is the most common reason why architects turn to Solarlux’s Ecoline and Highline series when choosing their bi-folding doors and windows. In order to add even more options for those seeking a uniform aesthetic for their facades, Solarlux has now added the Ecoline S and Highline S sliding doors to its range of thermally insulated, straight-edged aluminium profile systems. Both series offer uniform profile sight lines. The sight line in the sliding doors’ panel butt joint is a slender 55 mm, and there are no visible fixtures in the forend profile strips.
