System Description
The frame and leaves are multi-chamber profiles. The mitres connect with pinnable corner brackets.
Another advantage of this system is the quick and rational processing and the circumferential frame profile further ensures less waste.
The system achieves the best thermal insulation properties. Depending on the glazing and size used
Uw values < 1.0 W/(m²K) can be achieved.
The sliding hardware Roto Patio Inowa can be used with this system.
The AT 840 sliding system is compatible with other AKOTHERM systems.
