Silvercote Products, Inc. 161 East Erie Street, Chicago, 111. SILVERCOTE* REFLECTIVE INSULATION Insulation Silvercote Heat Reflective Surfaces--The silver-like surface of Silvercote reflective insulation consists of a polished, heat reflective coating applied to a special kraft paper. The importance of using a Silvercote radiant heat reflective surface in modern building construction is obvious when it is realized that from 50 to 80 per cent of the heat transferred across a normal air space is in the form of radiation. REFLECTIVE SHEET INSULATIONS IN ROLLS SILVERCOTE DUPLEX--A thin flexible vapor barrier and insulation consisting of two sheets of Silvercote paper bonded together with asphalt. ThiB material, containing two exposed Silvercote sur faces, weighs approximately 50 lbs per thousand sq ft and is manufactured in 500 sq ft rolls in widths of 36 in. or 52 in. to span two 16 in. or 24 in. standard framing spaces. These widths permit bow-in of the Silvercote over the room side of the framing members to form an air space "between the insulation and the interior finish. The water vapor per meability of Silvercote Duplex is 0.23 grains per sq ft per hour per inch of mer cury vapor pressure difference. SILVERCOTE SIMPLEX--An econom ical vapor permeable reflective insula tion designed for use where a vapor barrier is not required. Silvercote Sim plex is a single sheet of special kraft paper coated on both sides with the Sil vercote surface. It weighs approximately 30 lbs per thousand sq ft and is manufac tured in 500 sq ft rolls in 36 in. or 52 in. widths to span two 16 in. or 24 in. stand ard framing Bpaces. These widths per mit bow-in of the Silvercote over the exterior side of the framing members to form an air space between the insulation and the exterior Bheathing. The water vapor permeability of Silvercote Simplex is 99.2 grains per sq ft per hour per inch of mercury vapor pressure difference.

SILVERCOTE* REFLECTIVE INSULATION Insulation ON BLANKETS SILVERCOTE REFLECTIVE SURFACE ON VAPOR BARRIER SIDE A popular building insulation available in various thicknesses and faced on the vapor barrier side of the blanket with Silvercote paper. Manufacturers of this type of reflective blanket apply an as phalt coating to the back of the Silver cote paper for the twofold purpose of bonding the insulation material to the Silvercote paper and to lend vapor re sistant properties to the blanket at the room side of the insulation. SILVERCOTE REFLECTIVE SURFACES ON BOTH SIDES SILVERCOTE REFLECTIVE SURFACE ON BREATHER SIDE OF BLANKET INSULATIONS Silvercote paper is vapor permeable A deluxe insulation material utilizing the full insulation value of blanket insu lation, air spaces and two heat reflective surfaces. This double reflective blanket is manufactured with Silvercote Paper on the vapor barrier side and the breather side. and can therefore be used on the breather side of a blanket. When space permits the use of only one air space in conjunction with thick blanket insulations, it is de sirable that the air space be adjacent to the cold side (breather side). For this reason, many prominent manufacturers of mineral wool now furnish their re flective blanket with Silvercote on the breather side. Beg. U. S. Pat. Off. AVAILABLE UPON REQUEST Sllvercote's Handbook of "U" Values, 108 page illustrated booklet listing 12,852 "U" values of various walls, floors and ceilings--Silvercote's Handbook of "U" Values is unique in that it provides sum mer as well as winter "U" values. The Handbook's special listing of ceiling "U" values, indicating characteristics of downward heat flow will be of interest to those who are concerned with summer comfort as well as winter fuel savings. 1681
