(54) Wall or roof structure and building panel


(57) The present invention relates to a wall or roof structure and building panels (2). The wall structure comprises support pillars (10) and building panels (2) comprising a first surface sheet (4) and a second surface sheet (6) and an insulation material layer (8) between surface sheets (4, 6). The building panels (2) are secured to the support pillars (10) such that the second surface sheet (4) is arranged against a support pillar (10) for providing a support joint. The support joint is provided with an elastic support joint sealing (16) arranged between the support pillar (10) and the second surface sheet (4) for providing airtight sealing, and that at least one of the first and second surface sheets (4, 6) is provided with restricted thermal expansion for maintaining the airtight sealing by decreasing mechanical stress subjected to the elastic support joint sealing (16) due to thermal expansion.
