Roof/facade

1920-1940

The buildings of the 1930s in particular (the Nordic “funkis” period) often have no usable attic space. The roof pitch is low – almost horizontal – and roof coverings are therefore lightweight. The roof frame and joist dimensions are slender for the same reason.

In the example shown, the roof structure is laid on an inverted T-bar; however, laying on a timber wall plate is just as common.

Thermal insulation at the roof starts to become more commonplace: the figure shows (seaweed) mats that are mounted before the ceiling formwork is set up.
