AWS 75.SI+/ AWS 75 BS.SI+/ AWS 75 WF.SI+ –


Even brighter rooms, even greater possibilities! With aluminum windows, this is no longer a problem. Thanks to modern manufacturing advances, aluminum has proven itself to be an excellent material for windows. It allows for high stability with narrow face widths and, thanks to new technology, provides above-average thermal insulation.

With a Uf value of 1.3 W/(m2K) and a face width of 117 mm, the energy-efficient profile, SCHÜCO AWS 75 SI+, meets future thermal insulation standards. Invest in the future and increase the value of your property with brand new aluminum window systems. Contact us today to help configure custom windows for your project.

AWS 75.SI+

AWS Series

  • The SCHÜCO aluminum window AWS 75 BS.SI+ meets the toughest architectural requirements. With a concealed sash, a slim design with maximum visibility and light is possible.
  • The block window AWS 75 WF.SI+ is specially designed for narrow and uniform sight lines in the mullion-transom style.. The highly insulated system meets all requirements and perfect for commercial buildings.

Innovative Design and Maximum Comfort

The SCHÜCO series AWS 75.SI+/ AWS 75 BS.SI / AWS 75 WF.SI+ impresses in terms of design and comfort in all dimensions: Filigree post and frame profiles in slender face widths make large elements with considerable stability possible. This means that even large glazing are easily possible - for particularly bright living and working rooms with maximum transparency.

SCHÜCO also offers a wide range of opening types with maximum ease of operation. Extensive design options with cover shell variants are available. Additionally, you can choose between the Residential Line (RL) and Soft Line (SL) series. Another advantage is that the series is also compatible with SCHÜCO ADS/ADS HD entrance doors.

SCHÜCO creates sustainable building envelopes

Sustainability is an increasingly important issue given the world's growing population and use of natural resources. SCHÜCO takes sustainability and environmental issues seriously and has aluminum window systems follow this line, because their unique thermal insulation reduces CO2 emissions and thus protects the environment.


The Schüco AWS 75.SI+ window system is a special example of sustainability because it contains no harmful substances and is recyclable. This was tested by the independent Cradle to Cradle Products Innovation Institute in cooperation with EPEA GmbH in Hamburg and receiving silver label certification.

SCHÜCO SimplySmart - you save precious time when installing your windows

The AWS 75 series offers many advantages: For example, the innovative SimplySmart technology enables optimised thermal insulation and fast installation, as the centre seals at the corners of the sealing plane are not interrupted. As a result, the seals no longer have to be glued and installation is quick and easy. In addition, the glazing rebate insulation provides an improved contour and excellent insulation. The hardware system is also revolutionary AvanTec SimplySmart, which enables considerable time savings through simple click-in installation.

The higher the resistance class, the better the protection

Better Security with SCHÜCO

Modern aluminum windows used on the ground floor should at least meet the Resistance Class Two (RC2 N) requirements.

On the upper floor, resistance class RC 1 N is sufficient if the window cannot be reached via a fixed access such as stairs.

RC 1 N RC 2 N RC 3
  • The windows must offer protection against physical force. This includes: attacking, kicking and jumping, shoulder impact, pushing up and tearing out
  • However, RC1 windows have little resistance to levering.
  • The windows must meet the conditions of RC 1 N class.
  • In addition, there must be additional protection against the use of simple tools such as screwdrivers, wedges or pliers.
  • Levering them out should no longer be possible.
  • All the conditions of RC 1 N and RC 2 N and:
  • At the same time, the window must also be able to withstand the second tool used by the offender, such as a screwdriver or cow foot.

Protect your home with SCHÜCO security options including:


  • Lock monitoring with Schüco TipTronic
  • Lockable handles that secure the sash
  • Schüco AvanTec SimplySmart concealed fittings
