Insulation Duct MICROLITE ____ ===== G 1 A 5 S f B t R - --------- INSUlrATI NG'WOOL-- GLASS FIBERS inc. 18X0 Madison Ave., Toledo 2, Ohio Sales Offices and Distributors in Principal Cities MICROLITE is a low density, resilient, glass fiber insulating material with high thermal efficiency and sound absorption characteristics. It is made by the ELEC TRONIC-EXTRUSION PROCESS, de veloped, patented and used exclusively by Glass Fibers Inc. Application: Its light weight, flexibility and resilience make it easy to handle in large sections, easy to place properly and easy to fasten securely by modern meth ods. Microlite is simple to cut with a knife or shears, and can be bent around curved surfaces and easily fitted in irreg ular areas. In addition, this springy, airy insulating material is compressed ap proximately 4-to-l as it comes off the production line. The compactly wrapped rolls take up little storage space in fac tory warehouses and busy cutting-fabri cating rooms. Men like to work with Microlite because it's so soft and flexible--and because it doesn't cause itching. Properties: Composed of minute glass fibers of consistent uniformity, bonded together in blanket form, Microlite re sists fire, corrosion, vibration settling and effects of humidity. Glass fibers are inorganic; they provide no sustenance for fungus or bacteria, and no food for rodents or insects. Inch for inch, Micro lite is one of the most effective of all insulating materials, as shown below. Densities: 1 lb, \\fc lb, and 2 lbs per cu ft. Widths: 18, 24, 36, 48 and 72 in. Thickness: M, L 1 2 and 3 in. Lengths: 200 ft for and % in. thick. 100 ft for thicknesses more than % in. See how snugly Microlite fits into tight areas. That's because it's so resilient and compressible. Facings: Microlite is available with vapor barrier facing materials, applied to order. They may be made of foil, re flective coated paper, vinyl film and rein forced or unreinforced papers.

Distributors in All Principal Cities (Consult Classified Phone Directory) ULTRALITE glass fiber Duct Insulation and Duct Liner Characteristics of Ultralite. Ultralite Duct Insulation and Ultralite Duct Liner are composed of long, fine, textiletype glass fibers, bonded with a thermo setting resin. Both are manufactured and shipped in blanket-like rolls. Both are immune to fire, rot, corrosion, age, rodents and insects, odors, vibration, and are low in moisture absorption. Ultralite is resilient--quickly returns to original dimensions after pressure or bumps during or after installation. Application Characteristics. Ultralite Duct Insulation and Ultralite Duct Liner are exceptionally light in weight. Can be cut readily with a knife, quickly run around curves and corners without special fitting. Can be adhered with adhesives, metal screws and washers, even staples. Ultralite is not unpleasant to handle. Extreme simplicity of application keeps applied costs down. Ultralite Duct Insulation (Thermal). A highly efficient "wrap-on" type ther mal insulation weighing only 1 oz per board foot. Available plain or with your choice of a number of facings already adhered to insulation (when a vapor barrier and/or a base for finished appearance on duct runs is required). Shipped in compressed rolls.
