Limitless light

TRIESTE was designed to conceal the sash inside the wall, bringing out the beauty of the glazed surface which will look like a clear curtain of glass.

TRIESTE does not only deliver a minimalist look, it also provides excellent thermal insulation. It was designed to cope with the most adverse weather conditions and has excellent water-tightness and wind-resistance, ensuring protection and well-being in all circumstances.

TRIESTE also gives endless options for personalisation. You can choose from a system with two or three tracks or go for a Pocket solution which will hide the sashes inside the wall. It is ideal for projects entailing large glazed areas and a seamless aesthetic.
Option of installation with a flush threshold.
