About us

The QuinLine® system

The 5-chamber profile system QuinLine® is an independent system that is used exclusively for the construction of the QuinLine® 74 and the QuinLine® 84. Technically thought out down to the smallest detail, it offers a wide range of options for use as balcony or patio doors or even in a conservatory. The width and depth of the range is unique for plastic lift and slide doors. The threshold variants alone range from the standard threshold, renovation threshold, to the barrier-free low threshold.
