This thermal insulating and bituminous waterproofing board contains: (i) a modified bitumen layer containing, as a principal constituent, a mixture of bitumen and at least one inorganic filler, which layer is formed in the form of a thick board; (ii) a flat sheet laminated on each surface of the modified bitumen layer, said flat sheet consisting of a fibrous sheet, and; (iii) a thermal insulating material layer bonded, via the flat sheets, to one surface of the modified bitumen layer. This thermal insulating and bituminous waterproofing board can be easily and reliably applied onto a substrate without any complex procedures and, also, without causing any damage to the thermal insulating material.</p> |
