Telescopic steel frame and wooden leaf door. The frame is made of bended electro-zinc coated steel profiles (1.5 mm thickness)
and adjustable counter frame to the wall thickness. A perimeter rubber seal ensure the necessary tightness against cold smoke,
as well as a high acoustic attenuation.

The leaf is made of a solid wood edge and contains acoustic and thermal insulating materiais according to TRIA's construction system.

The use of intumescent seals ensures the necessary tightness against flames and hot gases. An automatic drop seal can be incorporated into the leaf.

The pivoting behavior of the door is ensured by hidden or visible hinges.

The automatic closing of the leaves is ensured by a hidden or visible door closer.
