Insulation MICROLITE -- GLASS FIBER ---- ' INSULATING WOOL GLASS FIBERS inc. 1810 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. 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. Dimensions: Densities: 1 lb, 1}4 lb, and 2 lbs per cu ft. Widths: 18, 24, 36, 48 and 72 in. Thickness: %, 1, 1H, 2 and 3 in. Lengths: 200 ft for Yi and Yi in. thick. 100 ft for thicknesses more than % in. Facings: Microlite is available with vapor barrier facing materials, applied to order. They may be made of foil, re One of many fast methods for Microlite application is with Stic-Klips, as illustrated above. flective coated paper, vinyl film and rein forced or unreinforced papers. Outer Wrap of Vitron Vapor Barrier Mat A strong outer cover for insulated ducts and pipes that are exposed to weather or require an outside vapor barrier is pro vided by Vitron Duramat, made of an asphalt and tar compound over a base of glass fiber mat and reinforcing glass yarns. It sheds rain and snow and provides a tough protection against im pact damage to the insulation. Made in 36 in. width and thicknesses of .060 in., (TYPE 252) and, .0375 in., (TYPE 251).

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. (See Sweet's File (Arch.) or write for AIA File 37-D-2) Thermal Efficiency of Ultralite Duct Insulation is shown in table at right. Tests were conducted by independent laboratories with ASTM approved, guarded hot plate methods.

A sound-absorbing insulation to be applied to interior of duct. Effectively absorbs objectional fan, air-rush and trans mitted noises. Also an excellent ther mal insulation that can be used on the exterior of duct. Weighs only 2 oz per sq ft in the in. thickness. Won't break, chip or dent. Available in in. and 1 in. thicknesses, coated one side with a fire resistant coating. Can be adhered e metal through brakes and shears.
