The renovation of the Mayrhof in Trins combines several best-practice solutions in one project. In particular, the use of a newly developed façade system and an extension using a house-in-house concept allow architectural and building physics aspects to harmonise with each other. During intervention the most important things always kept in mind were the external appearance and the woodwork in the stube. The very individual shape of the external walls made much work on details necessary. The external wall paintings refers to the buildings history.
As a result of the growing population in urban center the population in Trins also increased. Living space is often being created through demolition and new building. The Mayrhof demonstrates an inverse trend and shows how a modern multigenerational home can be built in accordance to traditional architecture and innovative technological concepts. A special focus has been laid on the external appearance so that the design plays with its former functions and fits in the surrounding architecture.
As a result of the renovation the wall thickness increased. The historical paintings are hidden, conservated under the facade panels. A focus has been laid on environmentally friendly materials. As a result, insulation is often made of hemp or cellulose, ceilings and walls out of wood.
- U-value (pre-intervention) [W/m2K]:2,128W/m²K
- U-value (post-intervention) [W/m2K]:0,119W/m²K
The windows have been replaced. The new wooden windows carried in a local style out were pre-installed into the custom-made wall elements also made of wood. The optimized position of the window frames in the insulation layer increases the thermal comfort and reduces the risk of building a condensate due to minimized thermal bridges.
- Existing window U-value Glass [W/m2K]: 5,0
- New window U-value Glass[W/m2K]: 0,8
- Existing window U-value Frame [W/m2K]: 3,0
- New window U-value Frame [W/m2K]: 0,75
