1,064,812. Heat insulation of ships' structure. MERSEY INSULATION CO. Ltd., and N. A. ROBERTS. June 19, 1964 [June 22, 1963], No. 24922/63. Heading B7S. [Also in Division F2] The reinforced outer surface 1 of a chamber e.g. of a ship's hold or engine casing is thermally insulated by gluing to the reinforcing beams 2a flexible sheet 3 of high heat reflectivity and a layer 4 of low thermal conductivity. The flexible sheet 3 may be polythene, polyester, paper, woven fabric, glass cloth or metal foil and if non-metallic may be coated with aluminium. The layer 4 may be glass fibre glued to sheet 3 or foamed polyurethane sprayed on the sheet 3. The whole insulation is covered with an outer lining 5 of metal, plywood or resin impregnated glass cloth or asbestos cement sheeting either glued to layer 4 or bolted at 6 to the reinforcements 2. In a modification the outer lining is spaced from the second insulating layer by an air gap. In a further modification, Fig. 3 (not shown), pipes (24) are placed between the second insulating layer (23) and another flexible heat-reflective sheet (26) and a low thermal conductivity layer (27). An air gap (31) separates layer (27) from outer lining (29). |
