Kenneth Lee Jenkins received US Patent No. 3,623,938 on November 30, 1971, filed May 7, 1970.

The patent's abstract:

A strong, mineral aggregate insulation board of lowered thermal conductivity is provided by incorporating 40-80 percent by weight of ultrafine particles of expanded volcanic glass that is 60 mesh and finer particle size, and 5-30 percent by weight of mineral fiber. Short absorbent vegetable fibers are included in the board for strength. Sizing agents are also often added to impart water resistance to the board, and additional adhesive tack materials, or binders, are sometimes added to further increase board strength.
