H.O. SCHLÜTER CLASSIC
Our standard window system fulfills all the requirements of a modern window and combines excellent thermal and sound insulation properties.
Using slender profile sightlines and a narrow installation depth, it can be easy used in new building and renovation projects.
The thermal insulation U-value on a standard window is between 0.21 - 0.23 Btu/hr-sq ft-°F but values as low as 0.13 Btu/hr-sq ft-°F are reached if the frame and sash are filled with ProEnergyTec insulation foam. It can take modern triple glazing or special functional glazing up to 50 mm thick and has sound insulation up to 46 dB.
Different U-values are possible depending on the frame/sash combination, glass, and steel insert. Contact us for more details.

Color Options and Finishes
All of our windows are covered with a high-performance laminate film, especially designed and formulated for harsh radiation, freezing temperatures, and tropical conditions found in North America.
This high-performance film retains its beauty throughout its service life and is highly ultraviolet, pollution, and salt-air resistant. The material’s low surface tension makes it inherently dirt-repellent and therefore easy to clean, even graffiti can easily be removed with a special cleaner. Because of this excellent performance, all of our surface finishes come with a North American Warranty for up to 20 years!

Technical Drawings
We provide a full range of technical drawings for every project and work closely with the architect to overcome any obstacles during the design phase. We are on hand 24/7 if you need to use our expertise.
All of our technical drawings are shown in mm for precision. If you prefer to receive drawings in inches, our team of designers and planners will happily make the conversion for you.
Every window we manufacture is designed from scratch to suit the needs of the building, so the dimensions, glazing, chambers, and steel reinforcements shown in this image may be different depending on your project specification.
