An Innovative System

This model is based on an innovative operating system. The leaves are installed with a mechanism that allows them to be raised during the opening manoeuvre and lowered during the closing manoeuvre. This feature allows the closed door to rest on upper and lower longitudinal seals, guaranteeing its interlocking in any position.

It is possible to meet leaves at 90º corners without mullions. In addition, in the fixed and sash configuration, the rail of the fixed zone remains hidden, which gives a minimalist and clean look to the design of your window.
