- | In timber construction plywood I-beam structures are often used so that the proportion of thermal bridges through wood can be reduced, but solid timber constructions are also used as they can be put into effect by a wider range of craftsmen. | + | In timber construction plywood I-beam structures are often used so that the proportion of thermal bridges through wood can be reduced, but solid timber constructions are also used as they can be put into effect by a wider range of craftsmen. Often a cross layer or a combination with EIFS is used to reduce thermal bridges. |
Just as common is the mixed construction with a solid supporting structure (reinforced concrete partitions or reinforced concrete skeleton structure) together with timber panel components for the external walls. Both can also be unitised which allows for shorter construction times.\\ | Just as common is the mixed construction with a solid supporting structure (reinforced concrete partitions or reinforced concrete skeleton structure) together with timber panel components for the external walls.

- | Concrete formwork bricks of polystyrene or PS with expanded clay are used mostly for detached houses. Wall systems with vacuum insulation panels using films or steel plates are used more and more frequently, but due to the technique and the required quality control they are very expensive. Passive House suitable solutions are even available for classic steel constructions.\\ | + | Concrete formwork bricks of polystyrene or PS (" |
