Lift/Slide System
AT 750 HS

System Description

The frame and leaves are multi-chamber profiles. The mitres connect with pinnable corner brackets. The system achieves the best thermal insulation properties, so that you (depending on the glazing and size used) can reach Ud values <1.0 W/(m²K).

Another advantage of this system is the quick and rational processing. You can you all lift/slide hardware of notable manufacturers with a leaf weight of max. 250 kg, and with special hardware even up to 400 kg. The AT 750 HS sliding system is compatible with other AKOTHERM systems.
