Roof construction, assembled using two types of plastic roof elements with different specific mass values

摘要

The two types of roof elements (4-12) are both made from plastic, one type having a lower specific mass than the other. A roof construction (1) comprising roof elements which are supported on an underlay and made essentially from plastic. Roof elements of a first type (4-9) with a sloping top surface are arranged side by side at roughly the same height, in order to form a sloping roof surface for a pitched roof. A number of roof elements of a second type (10-12) with an essentially rectilinear cross-section are used to support roof elements of the first type. The roof elements of the second type essentially comprise a plastic material with a lower specific mass than the roof elements of the first type. An Independent claim is also included for the roof elements of the second type.
