Abstract
A dual thermal barrier hollow comprised of separate metal shapes joined together with a non-conductive adhesive tape and a thermal barrier material.
Claims13
A dual thermal barrier lineal metal hollow comprising a pair of metal shapes adjacent each other in a spaced apart relationship, each of said metal shapes having a pair of spaced apart thermal barrier receiving channels and a tape receiving surface adjacent to and interiorly of each channel;
- attached to each of the two metal shapes is a non-conductive dual faced adhesive tape placed on a tape receiving surface of each of the metal shapes, the shapes being so positioned with respect to each other that a thermal barrier receiving channel of one shape is adjacent a thermal barrier receiving channel on the other shape and that the two thermal barrier receiving channels together and the tape adjacent thereto form a larger thermal barrier receiving channel, and thereby form two larger thermal barrier receiving channels spaced apart from each other;
- a thermal barrier material substantially filling each of the larger thermal barrier receiving channels thereby forming a dual thermal barrier hollow having structural integrity.
