<p>An improved material-particularly suited for the thermal insulation of building structures, such as residential housing, and a process for making the same, are disclosed. The thermally insulating (28) composite comprises a low-density (32) cellular, fiber-containing, cementitious material (32) and at least one structural surface element (30) made of the cellular, fiber-containing, cementitious material, the structural surface element (30) of which has a higher density than the low-density, cellular, fiber-containing, cementitious material (32) from which it is formed therefrom and integral therewith. The thermally insulating composite is made by placing a foam of the low-density, cementitious material having entrapped gas therein, in an enclosure at least part of which is permeable to the gas and the liquid medium of the foam, and applying pressure to a surface of that enclosure to remove the gas and the liquid medium at the permeable enclosure.</p> |
