Comprehensive roof window replacement in Weimar. How professional installation improved the comfort of 18 apartments.
Modern interior architecture increasingly focuses on people’s well-being. In attic rooms, roof windows play a major role in determining the character, functionality and overall comfort of the space. They support effective air circulation and ventilation while also influencing the appearance of the interior.
Roof windows at the heart of a comfortable interior
Scale and varied architectural accessibility
The Weimar project was a demanding logistical and engineering undertaking. It involved replacing as many as 40 roof windows across 18 different apartments. The main challenge faced by the contractors was the considerable variation in access conditions and building structures across the individual properties. To ensure that the work proceeded efficiently without disrupting the residents’ everyday lives, a hybrid working model had to be implemented.
The installation work was divided into three advanced scenarios:
Installation from inside the building
The work was carried out directly from the living space and required strict attention to cleanliness and the protection of finished interiors.
Hybrid installation from inside and outside using scaffolding
Advanced Krause Stabilo system scaffolding was used, enabling safe work at heights of up to 12 metres.
Hybrid installation using aerial work platforms
In areas with the most difficult access, the work was carried out externally using mobile truck-mounted access platforms weighing up to 3.5 tonnes. The equipment was rented from Seifert Weimar, a local German partner.
Trained teams and the highest installation standards
The human factor was key to the success of such a complex project. Four specialised KRONmat installation teams were assigned to carry out the work.
The professionals involved in the project were certified installers who had completed demanding FAKRO training programmes covering installation and insulation techniques. They also had an extensive portfolio of previous projects and unique experience in working under real and often unpredictable construction-site conditions.
Key aspects of KRONmat’s professional installation service
- Precise removal The old windows were safely removed without damaging the existing roof structure or interior finishes.
- Elimination of thermal bridges The new windows were precisely connected to the roof’s thermal insulation and moisture protection layers, ensuring long-term weather tightness.
- Ergonomics and occupational safety Work at height, including the use of 12-metre scaffolding and truck-mounted access platforms, was carefully coordinated in accordance with the highest occupational health and safety standards.
Results and benefits for investors and residents
The large-scale project in Weimar was completed successfully from both a logistical and technical perspective. The replacement of the roof windows delivered immediate and measurable benefits:
Improved thermal insulation Modern FAKRO glazing units effectively retain heat during winter and help protect attic interiors from overheating during hot summer weather. This is expected to result directly in lower energy bills.
Improved acoustic insulation Reducing external noise significantly improved the residents’ comfort, particularly during sleep and relaxation.
Improved appearance and natural daylight The interiors gained a modern appearance, while the improved access to daylight completely transformed the atmosphere in all 18 renovated apartments.
The Weimar project demonstrates that even the most advanced roof window can only perform its intended functions when it is installed correctly. The combination of FAKRO products with the expert knowledge and experience of KRONmat’s trained installation teams provides a solid foundation for the successful delivery of even the most demanding renovation projects in Europe.
