Insulation Reynolds Corporation Executive offices: 19 Rector Street, New York City Offices in Principal Cities REYNOLDS `METALLATION Description Metallation consists of bright sheet aluminum cemented to one or both sides of tough kraft paper. Available in roll form; in the form of Metallated *Ecod (a rein forced plaster base); and with heavy Sisalkraft paper base. These forms facili tate installation according to construction conditions and amount of insulation required. Metallation is primarily insulation ma terial for building construction involving hollow wall, floor or roof sections. Data on special applications on request. Its insulating effectiveness depends upon its influence on the enclosed air spaces it bounds or forms, not, upon its thickness. Hence, it must always face or divide an air space to have insulating value. Because it is windproof and moisture-proof, it always serves as an effective weather proofing barrier in any building section where used. How It Insulates Metallation insulates by repelling prac tically all radiant heat which strikes its surface. This portion of the total heat loss ordinarily flows unimpeded across air spaces. Type A or B Metallation dividing an ordinary air space reduces heat loss by convection, by dividing the air space into two air spaces and stops 95 per cent of the radiant heat loss across such air spaces. Metallation has equal effectiveness on either side of an air space, in vertical walls regardless of the direction of the heat flow. Characteristics Metallation is waterproof, windproof, vermin-proof and non-absorptive. It is light in weight and flexible, yet stiff enough to conform to angles and curves when not under tension or suspended. Its Type Width of Roll Length of Roll A 17 in. 176 ft 5 in.

S. Pat. Off. heat storage capacity is negligible, due to its light weight and limited mass. The aluminum used retains its reflectivity under all normal conditions, as the surface is protected by a transparent oxide which forms immediately on exposure. Tests recently conducted by Gordon B. Wilkes, Massachusetts Institute of Technology, show that visual brightness is not essential to good performance. * The,value of Metallation as an insula tion is(`unlikely to be impaired by internal condensatipn within the building section. Some external walls and roofs standing between cold exterior air and warm hu midified air indoors develop a " dew-point " temperature within them where condensa tion forms. Any insulating material that absorbs this moisture loses a part of its insulating value until it dries out again. Metallation being non-absorptive and un effected by moisture, retains its full value. Type A--Bright sheet aluminum ce mented to both sides of tough kraft paper with 1)4 in. plain paper margins exposed for nailing inside framing members. Applications: curtains between framing members 16 in. o. c. Type B--Bright sheet aluminum cemented edge to edge to both sides of tough kraft paper. Applica tion: curtains in air spaces. Also one surface as insulation; the other as moisture- proof membrane. Type C--Bright sheet aluminum cemented edge to edge to one side of tough kraft paper. Application: one side as insulation, the other in contact with building materials. Metallated Ecod--Bright sheet aluminum cemented to back of reinforcing plaster base.
