<p>The structure has parts e.g. panels, boards or bars, which are composed of wood material, and partially surrounds a plastic foam-insulating layer (34), where the insulating layer is composed of strongly packed plastic foam material. The insulating layer is produced with an operating pressure of more than 1100 kilo Pascal (kPa), where the operating pressure lies within a range of 1100 to 1300 kPa.</p> |
