Owens-Corning Fiberglas, Kaylo Pipe and Equipment Insulation, with Its 1953 Piping and Equipment Catalog (1953)

Two Owens-Corning Fiberglas product booklets filed together. The first (8 pages, publication 1-IN-759, stamped "Master File Copy") is "Kaylo Pipe & Equipment Insulation" for heated piping up to 1200 and 1800 degrees, and says that Kaylo, "a white, rigid hydrous calcium silicate heat insulation," contains no added binder but that "for mechanical effects, a small amount of asbestos fiber is included at the time of manufacture." The second (21 pages, IN6-A2, August 1953) is the catalog "Insulation for Piping and Equipment," covering Fiberglas pipe, block, blanket and duct insulations and Kaylo pipe insulation and heat insulating block, which it says were developed by Owens-Illinois Glass Company and distributed by Owens-Corning.

What it shows

The Kaylo booklet gives specifications, thickness tables and the Navy and military specifications (HH-I-523a, MIL-I-2781B) the insulation met. Owens-Corning sold Kaylo made by Owens-Illinois from 1953 and bought the Kaylo business in 1958 (see Owens-Illinois Sale of Its Kaylo Division to Owens-Corning Fiberglas (1958)); the first booklet, which calls Kaylo "manufactured by Owens-Corning Fiberglas Corporation" and includes Kaylo-20, is probably from after that sale.
