Window System AWS 90.SI+

Maximum thermal insulation combined with style and design freedom

The Schüco AWS 90.SI+ (Super Insulation) window system perfectly meets structural requirements while offering the greatest possible design freedom – including optimised thermal insulation and passive house certification.

As part of the Schüco AWS modular system for the 90 mm basic depth, the aluminium window offers a high level of flexibility for implementing attractive design solutions in building envelopes. Depending on architectural requirements, it can be configured as a punched opening, ribbon window or insert units in Schüco façades as well as in combination with Schüco door systems.

The wide range of opening types includes designs such as side-hung, turn/tilt and tilt/slide vents as well as barrier-free opening and double-vent units.

A further benefit for specifiers and architects is the wide range of profiles within the system platform, including corner mullions, structural mullions, symmetrical and asymmetrical mullions, as well as additional combination options, such as with Schüco sun shading and ventilation systems.

The window system with maximum thermal insulation thereby sets standards in terms of planning and design flexibility for the construction of energy-efficient, stylish building envelopes.

Schüco AWS 90.SI+, aluminium window system to passive house standard
With 90 mm basic depth.

Design features:
Face-fitted vent frame on the room side rebated by 10 mm from the frame edge, flush-fitted on the outside.
Thermally insulated insulating bars with three hollow chambers in the vent and foam insulation form the rebate for the co-extruded, hollow multi-chamber centre gasket, which is fitted with a foam core and has three fins to reduce convection.
The centre gasket is attached in the area of the insulation zone to the insulating bars by means of a double locating groove and hooking in at the rear.
The glazing rebate is thermally insulated by means of foam profiles which are tailored to the profile system and wrap around the outer insulating glass edge.
The system must be fitted with square glazing beads.
The glazing beads are installed with plastic clips to compensate tolerances.

Profile basic depths:
Outer frame, mullion, transom 90 mm
Vent frame 100 mm

Profile face widths:
Outer frame, bottom 109 mm
Outer frame, side and top 84 mm
Mullion 104 mm
Transom 104 mm
Vent frame (window) 36 mm
Vent frame (window door) 46 mm
Double-vent profile, narrow 62 mm
