A70US - Aluminum windows

Hidden Casement system

Thermal insulation Uf

from 1,2 (W/m²K)

Air tightness window

Wind tightness
(EN 12210) CLASS C5

The windows made in A70US system have casements that are unseen from the exterior side of the building. The position of the adjacent fixed and openable windows cannot be distinguished. In the row of adjacent fixed and openable windows all the compartments looks the same. The width of window frames is small, what makes the structure look slender and light.

Similarly to the standard solution, the A70 windows have the effective water drainage and ventilation system from the glass chamber and from the chamber between the casement and the frame. The ventilation and drainage holes are covered from the outside with caps made of plastics.

The characteristic feature of the A70US window system is that it is closely connected with the other A systems. Adapting such a structural design allowed achieving and applying many common elements, e.g. common glazing beads, gaskets, hardware, etc.
