The board has a support layer (2), on both sides of which layers (1, 3) of polyurethane are foam coated. One (3) of the layers (1, 3) is relatively thick and the other layer (1) relatively thin. The thick layer (3) is covered with a cover layer (4). This cover layer (4) and the support layer (2) are preferably diffusion-tight. Projecting adhesive strips (5) are disposed along two mutually abutting board sides (6). The board provides a very good thermal insulation with relatively low thickness. Unevennesses in the substrate can press into the thinner layer (1), ensuring a flush contact of the board. <IMAGE> |
