Abstract
Laminate insulation barriers including a highly insulative layer and a structural layer which has a cementitious structural matrix. The laminate insulation barriers are lightweight and more environmentally compatible than those currently used; they may augment, and even take the place of, traditional insulation materials which typically contain nondegradable, environmentally damaging materials.
Claims111
An insulation barrier having a laminate structure comprising:
- an insulating component which minimizes thermal conductivity across the insulation barrier such that the insulation barrier has a thermal conductivity less than about 0.1 W/m.multidot.K;
- and
- a structural component including a cementitious sheet formed from a cementitious mixture comprising hydraulic cement, a rheology-modifying agent, and water, the cementitious mixture being characterized in that it can be passed between forming rollers to form a sheet having sufficient cohesive strength while still in a green state and prior to hardening such that the sheet will be form stable as it exits the rollers free from underlying support so as to maintain integrity of the sheet, the cementitious sheet having a maximum thickness of about 2 cm, the structural component and the insulating component being integrally affixed together to form the laminate structure of the insulating barrier.
An insulation barrier having a laminate structure as defined in claim 143, wherein the easily oxidized metal is selected from a group consisting of aluminum, zinc, and tin.
An insulation barrier having a laminate structure comprising:
- a cementitious sheet formed from a cementitious mixture comprising hydraulic cement, a rheology-modifying agent, and water and being characterized in that it is form stable while in a green state in ten minutes or less after being positioned into a desired shape of the structural component, the structural component having a maximum thickness of about 2 cm;
- and
- an insulating layer having a thermal conductivity less than that of the structural component, the insulating component being formed from a cementitious mixture comprising hydraulic cement and water, the cementitious sheet and the insulating layer being integrally adhered together to form the laminate structure of the insulation barrier, the insulation barrier having a thermal conductivity less than about 0.1 W/m.multidot.K.
An insulation barrier having a laminate structure comprising:
- a cementitious sheet formed from a cementitious mixture comprising hydraulic cement, a rheology-modifying agent, an aggregate material, and water, wherein the cementitious mixture can be passed between forming rollers to form a sheet having sufficient cohesive strength while still in the green state and prior to hardening such that the sheet will be form stable as it exits the rollers free from underlying support so as to maintain integrity of the sheet, the cementitious sheet having a thickness less than about 1 cm;
- and
- an insulating component integrally affixed to the cementitious sheet to form the laminate structure of the insulating barrier, the insulation barrier having a thermal conductivity less than about 0.06 W/m.cndot.K.
