AS 80US
Hidden wing for a uniform facade.
The AS 80US system is a solution created for projects where the window sash is to remain invisible from the outside of the building. Thanks to this, regardless of whether the window is fixed or openable, all elements of the facade maintain a uniform appearance.
In addition, the AS 80US is fully compatible with other aluminum systems, providing extensive design possibilities and harmonious integration with other structures.
