Thermal insulation composite of cellular cementitious material
First Claim
1. A thermally insulating composite comprising:
- (a) a low-density cellular cementitious material containing fibrous material; and
(b) at least one structural surface element of cellular cementitious material formed from, integrally with, and upon at least part of the low-density material, the structural surface element containing fibrous material and having a higher density than the low-density material.

Abstract
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 composite comprises a low-density, cellular, fiber-containing, cementitious material and at least one structural surface element made of the cellular, fiber-containing, cementitious material, the structural surface element of which has a higher density than the low-density, cellular, fiber-containing, cementitious material 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.
