Window System AWS 75 BS.SI+

Block window with maximum thermal insulation and concealed vent for sophisticated design requirements

With its outstanding thermal insulation values and slimline design without visible vent contours, the Schüco AWS 75 BS.SI+ (Block System Super Insulation) block window system meets the highest energy-efficiency and architectural requirements with the greatest possible transparency.

The aluminium window is part of the Schüco AWS modular system for the 75 mm basic depth and features optimised characteristics in terms of function, energy efficiency and design.

Thanks to a high level of system flexibility, attractive design solutions are possible for a wide range of architectural requirements in the building envelope: as a punched opening, ribbon window or insert unit in Schüco façade systems as well as a “floating window”.

The wide range of opening types includes designs such as side-hung and turn/tilt vents as well as bottom-hung toplights.

Another benefit of the block window series is the wide range of profiles for the system, including corner mullions, structural mullions, symmetrical and asymmetrical mullions, vent glazing bars and insert outer frames as well as TipTronic vent profiles. They enable the use of the Schüco TipTronic SimplySmart generation of electrical fittings, a fully integrated drive for numerous opening types.

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

Schüco AWS 75 BS.SI+, highly thermally insulated aluminium block system
With 75 mm basic depth.

Design features:
Integrated system, the vent frames are positioned behind the rebate of the outer frames.
The clear dimension of the opening vents is identical to that of the fixed glazing and/or infill.
Face-fitted vent frame on the room side rebated by 10 mm from the frame edge.
The window vent is designed as an isolator.
Thermally insulated insulating bars in the window vent with several hollow chambers form the rebate for the co-extruded, double hollow chamber centre gasket fitted with a foam core.
For improved separation of heat transfer, this must also be designed with a fin.
The glazing must be partially bonded to the insulating bar.
For optimum thermal insulation, plastic glazing beads are used.
The joints of the external glazing retention beads are covered by the glazing gasket, which is designed as a vulcanised gasket frame.

Profile basic depths:
Outer frame, mullion, transom 75 mm
Vent frame, face-fitted 80 mm

Profile face widths:
Outer frame, bottom 66.5 mm
Outer frame 66.5 mm
Insert outer frame 50 mm
Mullion 107 mm
Transom 91.5 mm
Double-vent profile 83 mm
