Abstract
Abstract A method and apparatus for using phase-change compounds for insulating purposes. Selected phase-change compounds are stored in the voids of particles of suitable insulating materials that are maintained surface dry whereby temperatures walls and ceilings containing such insulation are maintained at a much more constant temperature than can be achieved using insulating materials alone.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
52 words
A method of insulating structures comprising the steps of forming an insulating material by substantially filling the voids of a porous carrier material particles with a phase-change compound while maintaining said particles in a surface dry condition; and positioning the insulating material adjacent to at least one surrounding wall of the structure.
Claim 2
Independent Claim
52 words
A method of insulating structures comprising the steps of forming an insulating material by substantially filling the voids of a porous carrier material particles with a phase-change compound while maintaining said particles in a surface dry condition; and positioning the insulating material adjacent to at least one surrounding wall of the structure.
Claim 3
Dependent Claim
21 words
A method as in claim 1, further comprising arranging the insulating material to be subjected to phase-change conditions at desired times.
Claim 4
Dependent Claim
25 words
A method as in claim 1, wherein the insulating material is arranged to be subjected to direct heat energy of the sun at desired times.
Claim 5
Dependent Claim
30 words
A method as in claim 3, wherein the insulating material is arranged to be subjected to a heat exchanger at desired times to change the condition of the phase-change compound.
