AWS 75.SI+ Schüco
AWS 75.SI+ — Aluminium Windows
Window system with super-high thermal insulation · Schüco International KG (Germany)
Schüco AWS 75.SI+ (Aluminium Window System, Super Insulation) is a window system from the German manufacturer Schüco International KG, introduced in 2005 and since then established as a standard series in many European countries. The system is part of the modular Schüco AWS platform and provides an installation depth of 75 mm with a Uf coefficient from 0.9 to 1.6 W/m²K, depending on the insulating insert configuration, at a sightline width of 117 mm.
Schüco SimplySmart technology, with a continuous centre gasket around the perimeter of the frame and sash, simplifies and speeds up production, while optimised glazing rebate insulation ensures consistently high thermal performance. The new-generation concealed Schüco AvanTec SimplySmart stainless steel hardware is installed using a click-in method, noticeably reducing assembly time while maintaining RC3 (WK3) burglar resistance.
Several design lines — Residential Line (RL.SI+), Panorama Design (PD.SI), and Block System (BS.SI+) — along with the Window Façade (WF.SI+) variant for ribbon glazing, open up broad architectural design possibilities. AWS 75.SI+ has been tested by the independent institute EPEA Hamburg and certified with the silver Cradle to Cradle label — confirming the absence of harmful substances and full recyclability.

The AWS 75.SI+ system offers several specialised design lines — each creating a distinctive architectural look on a single structural base with the same technical specifications.
Chamfered outer sash contours for a striking visual accent. Ideal for renovation and projects where a strong architectural identity is required.
A narrow sightline width from 56 mm for maximum transparency and natural light. A solution for panoramic glazing with a focus on minimalism.
A block system with a concealed sash and sightline width from 67 mm — an elegant construction with no visible sash contours for the most demanding architectural projects.
Uf from 0.9 W/m²K — one of the best figures in the Schüco range. With triple glazing, Uw reaches 0.88 W/m²K.
The highest class for serial window systems under DIN EN 1627 (WK3). Concealed AvanTec stainless steel hardware further enhances security.
A maximum Rw value of 48 dB — effective protection against traffic and industrial noise in urban buildings.
Tested by EPEA Hamburg and certified with the silver C2C label — confirmed material sustainability and full recyclability.
A continuous centre gasket around the perimeter of the frame and sash, with no corner bonding required — precise assembly and stable thermal performance.
Click-in installation saves assembly time; fully concealed inside the construction — clean profile lines outside and inside, with no visible hinges.
Mechatronic hardware for automating window opening/closing and integration into smart home and building management systems.
Sash weight up to 250 kg, dimensions up to 1700×2500 mm. AvanTec SimplySmart hardware supports an opening angle of up to 180°.
The aluminium profile resists corrosion, deformation, UV radiation and mechanical loads. Service life is 60 years or more.

Schüco AWS 75.SI+ (Aluminium Window System, Super Insulation) is a window system from the German manufacturer Schüco International KG, introduced in 2005 as part of the modular AWS platform and since then established as a standard series in many European countries. The system is designed for architectural projects with the strictest requirements for energy efficiency, security and facade appearance.
The base frame thermal transmittance Uf ranges from 0.9 to 1.6 W/m²K depending on the insulating inserts used — at the standard profile sightline width of 117 mm, the figure reaches 1.2 W/m²K. Using triple glazing with Ug 0.6 W/m²K and a warm-edge spacer, the overall window coefficient Uw drops to 0.88–0.90 W/m²K — one of the best results among serial aluminium window systems.
RC3 (WK3) burglar resistance under DIN EN 1627 is achieved thanks to the concealed Schüco AvanTec SimplySmart hardware, made of stainless steel and installed using the click-in method to save installation time. SimplySmart technology, with a continuous centre gasket around the perimeter of the frame and sash, eliminates the need for corner bonding, simplifying production and improving the stability of thermal performance. If required, the system can be fitted with TipTronic SimplySmart mechatronic hardware for integration into building automation and smart home systems.
Several design lines open up different architectural possibilities. Residential Line (RL.SI+), with chamfered outer contours, creates a distinctive visual accent. Panorama Design (PD.SI), with a sightline width from 56 mm, provides maximum transparency and natural room lighting. Block System (BS.SI+), with a concealed sash and sightline width from 67 mm, meets the most demanding architectural requirements. The Window Façade (WF.SI+) variant is specifically designed for the economical construction of ribbon glazing with a mullion-transom appearance.
Sound insulation Rw up to 48 dB under DIN EN 20140 makes the system an effective tool for acoustic protection in urban environments. Water tightness class 9A under DIN EN 12208 and air permeability class 4 ensure reliable tightness under adverse weather conditions. Wind load resistance corresponds to class C5/B5.
Maximum sash dimensions of up to 1700×2500 mm and a weight of up to 250 kg make it possible to create large-format constructions with an opening angle of up to 180°. Support for glazing units up to 61 mm thick allows for the use of highly efficient triple units and special safety and structural glass.
Schüco AWS 75.SI+ has been tested by the independent institute EPEA Hamburg and is certified with the silver Cradle to Cradle label — a standard confirming the absence of harmful substances in the materials and their full suitability for recycling into raw materials of the same quality. The calculated service life of Schüco aluminium profiles is 60 years or more. Logi24 offers supply, professional installation and warranty service for Schüco AWS 75.SI+ across Europe.
