For over 40 years, we have been manufacturing aluminum windows from the leading system manufacturer Schüco in our ultra-modern metal construction plant (Plant 2) in Berlin-Marienfelde.

With our diverse and innovative aluminum window systems, we consistently implement the most demanding architecture and technical visions. Our Schüco product range includes aluminum window constructions as insulating glass windows, block windows, composite windows, window façades and mullion/transom façades in various installation depths and design variants.

Our design standards are just as important to us as the functionality of your aluminum window. Whether for new builds or renovations, our Schüco aluminum windows meet all requirements in terms of energy efficiency, security, design, accessibility, comfort and sound insulation.

We pay particular attention to the sustainability – Cradle2Cradle certification – of our aluminum windows. The basic prerequisite for this is that all materials used are proven to be free of harmful substances and are manufactured in our “green” and highly sustainable Plant 2.

Our highly automated production enables us to ensure our high level of quality and on-time completion of the various projects.

Convince yourself of the quality of our aluminum windows and visit us in our showroom.

Tested and certified burglar-resistant security windows

Due to the increasing number of cases of burglary, the topic of burglary protection is also a particular focus of the work of police crime prevention. The aim is to raise public awareness of effective burglary prevention even more intensively than before. Together with cooperation partners from the insurance industry, industry associations and installation companies, the police launched the nationwide publicity campaign K-EINBRUCH.

Registered in the police manufacturer directory

Hans Timm Fensterbau is registered in the list of manufacturers of “tested and certified burglar-resistant windows” published by the police. Our timber windows, timber-aluminum windows and aluminum windows in resistance classes RC2, RC3 and RC4 are therefore considered “unreservedly recommendable” for good burglary protection. We would be happy to advise you in our showroom.


Visions need new innovative solutions. Together with our strong partners (investors, general contractors, architects, project managers), we develop new property-specific solutions and services for the economical and sustainable implementation of your wishes and ideas.

Every property is unique and requires individual solutions for successful implementation. We therefore support architects, investors and building owners at an early stage with targeted advice and digital services in the search, selection and planning of suitable constructions.

According to the motto “replacing chance with planning”, planning reliability has always been very important to us. With our professional planning department and experienced project managers, we design your specific project solutions using the latest CAD technology.
In our three ultra-modern Berlin plants with > 100 productive employees, we combine many years of experience with state-of-the-art CNC technology with end-to-end digitalization and a high level of automation for optimum process efficiency. Our high level of vertical integration and high degree of prefabrication enable time-saving assembly processes on the construction site.
Thanks to our own fleet of trucks and the use of our own logistics equipment, we generally deliver to our properties just in time, including to protect the elements on site. The professional installation of windows, doors and façade elements is carried out by experienced, specialized and well-coordinated installation teams.

To ensure the long-term value retention and thus the functional safety and usability of the structures, we provide you with personal support from our own specialists even after completion of the construction project.
