Flat or semi-flat element ( 1 ) including a partly or completely circumambient frame ( 2 ), which element ( 1 ) is manufactured through molding of a polymeric material. The element ( 1 ) includes a carrying structure, constituted by the frame ( 2 ), and an intermediate wall section ( 3 ). The wall section ( 3 ) is connected to the frame ( 2 ) via a resilient section ( 4 ), the resilient section ( 4 ) being a part of the wall section ( 3 ). The differences in the temperature related shrinkage between the frame ( 2 ) and the wall section ( 3 ) is absorbed by the resilient section ( 4 ), whereby warping of the element ( 1 ) is avoided. |
