New construction extension school building, Uettligen
2004
Here, a two-story rucksack addition to the existing building was to be realized, with adaptation of the existing eaves and transitions to the first building. The facade was to be created with a painted wooden formwork.
The project
The object was realized as a pure timber construction over a base floor in reinforced concrete. The ceiling above the ground floor and the flat roof were designed as box girders, with the lower slab as an acoustic layer.
The construction method
The walls are realized as timber frame construction with back-ventilated, horizontal external formwork. Spruce Rift / Halbrift class A / B was used for the exterior formwork. This was primed and painted with two coats of paint. For the roof, sloping insulation was laid over the box girder, and greenery was planted on top. The box girder itself is insulated with only about 1 / 3 of the total insulation thickness. This also acts as an acoustic absorption layer.
