Maintenance & Service

Preserving values through maintenance & service

We offer comprehensive maintenance/maintenance and repair services for windows, doors and façades.


The Schüco AWS 75 SI+ optimized window system is part of the AWS system platform.

The high degree of system flexibility enables use for a wide variety of applications: as a perforated window, as a window strip or even as an insert element in the façade. You are also free to choose whether a fixed panel or one of the different opening types should be installed. The right window for almost every application.

In combination with Schüco TipTronic, our windows can also be controlled electrically.

We set standards with ultra-slim and sharp-edged profile widths.

The Schüco AWS 75 SI+ optimized window system with its classic, flush, timeless casement design is the right window for almost any application and leaves nothing to be desired architecturally thanks to its various design variants.

Due to the narrow external face widths, aluminum windows are often used in listed buildings.

The Schüco AWS 75 SI+ optimized window system stands for maximum comfort.
It impresses with its ease of use, simple handling and optimum functionality.

First-class values in the categories of driving rain resistance, wind loads, serviceability and permanent function are achieved through sophisticated rebate geometry and sealing systems.

We implement very high noise protection requirements with special sound-insulating glass.

Opaque ventilation sashes, as pivoting sashes, combine rapid room ventilation with
high degree of architectural design freedom. In summer, the side-hung leaves can remain permanently open. The sashes are easy to operate and are ideal for combining with large glazed units and fixed glazing.

Add-ons such as opening limiters, sash brakes, gap ventilation and gap air limiters are available for increased living comfort and to ensure safe, convenient ventilation.

Anyone who builds barrier-free demonstrates foresight. Barrier-free elements allow for needs-based use in every situation.

With the Schüco AWS 75 SI+ optimized window system, we offer the right solution for every requirement and every building situation!

Barrier-free comfort components such as the comfort fitting, the cable ejector or the spring unit can be installed in the 75 mm installation depth and ensure verifiable operating forces in accordance with DIN 18040-2

  • 30 N for the tilt position
  • 5 Nm for handle actuation
The right aluminum window system for every thermal insulation requirement.
Our extensive system portfolio offers a selection of different construction depths and design variants to meet current and future requirements for energy-efficient buildings.

With the Schüco AWS 75 SI+ optimized aluminium window system, we achieve excellent thermal insulation values up to passive house suitability.

Timm stands for a high level of expertise in the field of security and has had a wide product range of certified security windows for decades, making us one of the few companies in Germany to be listed in the State Office of Criminal Investigation’s (LKA) list of manufacturers.

Depending on the requirements, we offer the Schüco AWS 75 SI+ optimized aluminium window up to resistance class RC 3.

Even when partially open (tilted), we offer security up to RC2 with the SimplySmart OpenSecure fitting.

Other security components (alarm contacts, alarm glass, alarm mats, etc.) are easy to integrate into aluminum windows.

Compatible element for modular construction in the new TIMM modular system

Unique and fully integrated overall architectural system with maximum standardization

In the modular TIMM system, all necessary and individually configurable additional components (sun protection, insect protection, fall protection, insect screen, window sill, threshold) are combined in a “window and façade module” around the window and are quickly installed as a complete system on the construction site after completion in the factory. The TIMM system therefore guarantees the greatest possible individualization with maximum standardization.
