Technical Specifications
Functionality
The AWS 90.SI+ is engineered for maximum energy efficiency. Its 90mm frame depth accommodates the widest insulation zone in the Schueco range, supporting triple-glazed units up to 62mm. The system can achieve overall Uw values that meet passive house certification requirements.
How It Works
The extended 90mm frame depth allows for a larger insulating zone with multiple thermal break barriers. The profile geometry is optimized for minimal thermal bridging, while the deep gasket grooves accept advanced sealing systems for Class 4 air-tightness. The flush interior sash option creates a minimalist aesthetic with the sash sitting level with the frame.
