The beam structure of the walls and ceiling is individually made of wood in accordance with the architect’s design. Full planning freedom is available for this. The supporting framework consists of a wood frame made up of spruce elements. The intermediate spaces between the walls are filled completely with environmentally-friendly insulating material soft fibreboard. The soft fibreboard keeps its shape and prevents the insulation from settling, and therefore also prevents empty spaces, condensation and moisture. The inner side of the wood frame construction is then closed with gypsum fibreboard and plasterboard. This double cladding allows furniture to be assembled at any desired point.
The outer wall is then finally closed with natural cork external thermal insulation. A base coat and finishing coat and/or alternative facade formwork are used to finish the house’s outer wall.

Thanks to the high prefabrication level of the Rubner Haus, the walls are already provided with windows, shade systems, doors and electrical as well as plumbing fixtures at the factory, provided that these items are included in the delivery.
