Low Initial Cost--rease, rapidity of application and no dirt or waste make the initial cost of Alfol lower than for most other insulations. cold, prevent condensation and block sound transmission. Alfol Insulationlayers spaced ap proximately Ys apart Conductivity-- Panel Type JBS Crumpled Type JS8 In its simplest form it con sists of successive layers of crumpled special metal foil applied approximately H" apart. The outside layer of Alfol is covered with a re movable metal jacket. Alfol is a modern, scientifically designed insulation which effectively and econo mically meets all high and low temperature require ments. Some of the many advantages are: 1. Negligible Weight- only H oz. per board foot. 2. Highly Efficient--con ductivity .28 B.t.u. per hour, per sq. ft., per 1 F temp, difference, per inch thick. 3. Non-Inflammable -- being metal it will not burn. 4. Impervious to Mois ture--repels all mois ture attacks thereby retaining its uniform high insulating value. 5. Durable -- unaffected by vibration, will not disintegrate, crumble, warp or settle. APPLICATION Alfol I nsulation is applied in never riiore than 3 crumpled layers to one inch thick- ness. The high re- reflecti vity of the foil ( 95% ) and the non-con Alfol Insulation for Heating and Ventilating Dudt ducting air spaces between the layers, pro vide Alfol's amazing efficiency. It is never necessary to wad or pack Alfol in place. As a matter of fact, when applied loosely in corners, slots, etc., its efficiency is actually increased. All Alfol joints are lapped in each layer about I" and staggered with respect to joints in adjacent layers. All stiffeners, studs, rivet heads, etc., pro truding into the insulation are lightly covered over with the same number of layers used on sur rounding surfaces.

Double-Ply (XX), about Ho* thick. Triple-Ply (XXX), Ho* thick; and Inch Quilt, lHo* thick. U. S. Government Bureau of Stand ards Letter Circular No. 227, reporting' tests of numerous Insulating Materials, gives Cabot's Quilt a Thermal Con ductivity rating of 0.25 per inch, which was equalled by only two other insula tors, regardless of cost. Tests conducted by Prof. Gordon B. Wilkes, of the Massachusetts Institute of Technology, show the following savings in heat leakage in different methods of construction, by the use of Cabot's Quilt. Conductivity " Uninsulated H " 1Percentage 1 Heat Saving U Uses--For insulating side walls and roofs ol buildings against cold in winter and heat in summer, for insulating cold storage buildings and ice houses, refrigerators, etc.; for sound proofing partitions and ventilating ducts. Description--Cabot's Quilt is a felted springy matting of Zostera Marina, a marine plant, stitched between two layers of Kraft (Standard Quilt), non-inflammable Kraft (Anti-Pyre Quilt), asbestos (Asbestos Quilt), water-proof paper (Water-proof Quilt). Cabot's Quilt has an insulation value inch for. inch excelled or equalled by only two other insulators, both greater in cost. Permanent--Because of its natural prop erties, no special chemical treatment is re quired, and Cabot's Quilt will not pack down, rot or harbor insects or vermin. Quilt shows no deterioration after having been in actual use for over forty years. Fire Resistance--Standard Quilt is natu rally fire resistant and when made with the new non-inflammable Kraft paper (Anti-Pyre Quilt) can be used in any fire-proof building. Easy, Low Cost Application--Quilt can be applied at the lowest labor cost. Being flexible it fits into corners or around projec tions without danger of cracking. Requires no special preparation or smoothing of walls or floors in cold storage work. Easily adapts it self to lining or covering of ventilating ducts. Readily cut with ordinary knife or shears. Widths--Quilt is made in 36" and 18" . widths. 18" Quilt is quickly applied between studs and roof rafters.
