Energy efficient building system
First Claim
1. A building formed from a number of load-bearing preformed insulating blocks, said building comprising a floor formed by a number of preformed insulating blocks joined at the edges to form a continuous floor,a number of walls supported on said floor, each of said walls being formed from a number of preformed insulating blocks joined at the edges to form a continous wall and a roof formed by a number of performed insulating blocks joined at the edges to form a continuous roof structure and being supported on said walls,said insulating blocks being formed from a molded foam and a fiber reinforced cement coating covering the entire exterior surface of said roof, said walls and said floor, and adhesivemeans joining said edges of the blocks to form said walls, roof and floor.

Abstract
A foam-cement building having the walls, roof and/or floor formed from a plurality of self supporting foam building blocks of varying density with a strong thin continuous structural and architectural coating on the surface of the blocks, the coating being formed from cement, reinforced with a fiberglass mesh and fiberglass roving strands, the blocks being interconnected by a mechanical key system or splines to form a monolithic structure.

1. A building formed from a number of load-bearing preformed insulating blocks, said building comprising a floor formed by a number of preformed insulating blocks joined at the edges to form a continuous floor,
a number of walls supported on said floor, each of said walls being formed from a number of preformed insulating blocks joined at the edges to form a continous wall and a roof formed by a number of performed insulating blocks joined at the edges to form a continuous roof structure and being supported on said walls, said insulating blocks being formed from a molded foam and a fiber reinforced cement coating covering the entire exterior surface of said roof, said walls and said floor, and adhesive means joining said edges of the blocks to form said walls, roof and floor.

5. A composite load-bearing building block adapted be joined in edge to edge relation with a corresponding block to form a wall, roof or floor, said block comprising a foam core having a sufficient width to form a load-bearing structure and
a coating on at least one surface of said core, said coating being formed from a composition including Portland cement, sand, cut fiberglass roving strands and a polymer adhesive, said composition being applied to a reinforcement grid located on the outer surface of said core, whereby said grid is embedded in said cementitious coating.

11. A load-bearing thermally insulating fire-resistant building wall formed from preformed blocks joined at their edges to form a continuous wall, each block comprising
a foam core having a thickness of 6 to 24 inches and a coating on the inside and outside surfaces of said core, said coatings including a fiberglass reinforced fabric on the surfaces of said core and a cementitious material, including cut fiberglass roving strands, applied to the external surface of said fabric to a thickness of approximately 1/4 to 1/2 inch to secure said fabric to said core whereby said blocks have integrally related, load-bearing, tensile and fire-resistant characteristics.
- 12. A load-bearing building block comprising a foam core having a length up to sixteen feet and a height up to four feet and a cementitious coating on at least one surface, said coating including a reinforcement grid and cement composition having fiberglass roving strands mixed therein, said composition penetrating said grid and bonding said coating to said core, said core having a width which, when combined with the reinforced coating forms a load-bearing structure.
-
17. A building having external walls formed from a plurality of preformed load-bearing cement foam core blocks of a predetermined configuration adapted to be joined at their edges at the building site to form a rigid wall, each block comprising
a foam core up to sixteen feet in length and four feet in height and of a sufficient width to be self-supporting, means on each edge of said core for matingly engaging the adjacent blocks and a cementitious coating on the exterior surface of said foam core to enhance the load-bearing capabilities of said wall, said coating including a reinforcing grid located on the surface of said core and a composition covering said grid, said composition including predetermined amounts of cement, sand, cut fiberglass rovings and a polymer adhesive, said grid being embedded in said composition and bonded to said core whereby said block has sufficient load-bearing strength to form the building walls.
