Klostergebäude Kaiserstrasse - Glass wool insulation - 340 mm

The roofing to the street was made of the original slate, the one to the courtyard-side was done with Eternit lace stencils and the formers in zink. The roof was equipped with a high quality intermediate rafter insulation and an inside, mineral rafter insulation. The roof gaiters were insulated with highly efficient insulating material. The gallery floor is illuminated on the court side via generous glass fronts of the formers. In order to ensure an appropriate illumination of the attic apartments, 4 vertical light bands with 4 roof windows each were installed symmetrically to the south gable-end in the roof area. The fixed sunblinds avoid the summer overheating, but allow solar heat gains to be used in the winter. On the one hand, they guarantee a view into the open and on the other hand they create a homogeneous roof surface. In order to be able to mount the lamellas flush with the roof surface, an installation detail has been developed in which the level of the roof windows is located on the inside. The lowest window of each lightband is openable and manufactured with a ladder, so that the second escape and rescue route is given from each unit in the attic. The roof surfaces were covered with historic slate cover and all zinc plating was redone.

• Hybrid Roofing Materials: The combination of original slate on the street side and Eternit lace stencils on the courtyard-side optimizes both durability and aesthetic appeal. Slate is long-lasting and weather-resistant, while Eternit provides a modern, efficient roofing solution. • High-Quality Insulation: The use of intermediate rafter insulation and mineral rafter insulation inside ensures excellent thermal efficiency. This reduces heat loss in winter and keeps the interior cool in summer, leading to energy savings and enhanced comfort. • Innovative Sunblinds: The fixed sunblinds are designed to prevent summer overheating while allowing solar heat gains in winter. This dual function contributes to maintaining a comfortable indoor climate year-round. • Light Bands and Roof Windows: The installation of vertical light bands with roof windows, particularly on the south gable-end, maximizes natural light penetration. This not only reduces the need for artificial lighting but also enhances the living experience in the attic apartments. • Escape and Rescue Route: The design incorporates a practical safety feature where the lowest window of each light band is operable and equipped with a ladder, ensuring a secondary escape route from each unit. • Flush-Mounted Lamellas: The lamellas are mounted flush with the roof surface, contributing to a homogeneous appearance and preventing any disruption in the roofline. • Energy Efficiency and Environmental Consideration: By combining high-quality insulating materials and strategically placed windows, the roofing system is energy-efficient, reducing the carbon footprint and aligning with environmental sustainability goals.
