for new ideas.

One of the specialities of OST is modern glazed façades and walls with perfectly executed, handcrafted mullion-transom constructions. There are virtually no limits to the ambitious projects you can implement with them.

They let you, for example, open up the ground floor across its entire width or a whole wall up to the ceiling. Or an entire gable up to its apex. Mullion-transom façades also let you transition to special self-cleaning roof glass. Or explore new architectural freedoms with imaginative shapes made of wood, glass and aluminium elements.
