<p>An insulated damp-proof course comprises a flexible plastics membrane (12), for example of polythene, and a thermal insulating sheet (14) bonded to one side of the membrane (12) by a suitable adhesive. The sheet (14) is formed of an expanded or extruded polystyrene foam and is bonded under pressure to the membrane (12) so as to enable the bonded structure (10) to be rolled upon itself without damage to the material. Such an insulated damp-proof course is extremely advantageous not only for its inherent properties but also the ease with which it can be handled and laid due to the fact that it can be made available in a roll.</p> |
