A laminate panel having desired characteristics even though the materials having these desired characteristics are not compatible in at least one aspect, is disclosed . One of the substances having the desired characteristics may be moved away from the other substance and a different substance compatible with the substances may be used between the two substances. For example, the laminate panel includes a liquid impermeable layer that substantially prevents the penetration of moisture. The panel also includes a layer of a balancing substance disposed close to the liquid impermeable layer to balance another layer of the laminate panel. A kraft paper sheet coated with the balancing substance on one side and a substance providing good bonding with the liquid impermeable layer on the other side, may be used to provide the desired balancing characteristic. <IMAGE>
