Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
111 words
A room ceiling comprising: ceiling panels attachable together along adjacent edges; a supporting structure for supporting said panels in a desired configuration to form a ceiling; tubular pipes being above, and in direct contact with said panels, said pipes having a flowable medium passing therethrough, said pipes being formed of flexible tubes disposed closely adjacent one another to form flexible mats of said tubular pipes; wherein said pipes possess a degree of flexibility such that said pipes will bend under their own weight to conform to the desired configuration of the ceiling; wherein said flowable medium has characteristics for heatin and cooling; and wherein a predetermined room temperature may be achieved.
