Offset sliding system


WICSLIDE 150 PS is a hybrid solution because it combines the advantages of a sliding system with the features of a window. The patented central sealing system guarantees optimum water-tightness – up to four times greater than standard sliding doors. Thanks to excellent thermal insulation and watertightness, the WICSLIDE 150 PS offset-sliding system is the innovative solution to meet the challenges of climate change. Specifically developed for a high level of comfort with the secure micro-ventilation system, WICSLIDE 150 PS offers an innovative solution and ensures smooth low-noise operation. The profiles have been extruded from Hydro CIRCAL 75R aluminium – a top quality aluminium alloy composed of at least 75% recycled end-of-life aluminium (post-consumer scrap).
