Abstract: A PCM heat insulation blanket (10) is positioned in a wall structure of a building for modulating the transfer of heat to and from the controlled internal temperature of the building structure. The PCM heat insulation blanket includes an array of pods (12) with one group of pods 12A containing a first PCM and a second group of pods containing a second PCM 12B having a different phase change temperature than the first group of pods. The pods with different PCMs are substantially uniformly intermixed among each other. The pods are formed of laminated sheets, each of which may include a metal foil that is vapor impermeable and tends to maintain the PCMs in the blanket at approximately the same temperature, and which also functions to reflect radiant heat away from the temperature controlled internal space of the building structure.

Abstract: A plurality of sheet supports 50 or 70 of approximate rectangular configuration are placed on adjacent purlins 14 of a partially completed roof of an industrial building, about the second row of roof insulation support carriages 10. When the carriages are advanced along the lengths of the purlins to apply the sheet material 34 to the purlins, the sheet supports 50 or 70 move in unison with the carriages of the second row of carriages and the rear segment 54 supports the sheet material in the spaces 60 over which the carriage is mounted and the side segments 56 and 58 support the sheet material extending from the first row of carriages in the next adjacent spaces between the purlins. This avoids the sagging of the sheet material between the purlins at the time when the hard roof panels 37 are fastened to the purlins.

Abstract: The heat insulator includes a lower sheet (14) that is larger is both length and width than the upper sheet (12) so that the heat insulator can span over objects such as purlins, rafters and obstructions in a roof structure while maintaining the air gap (20) between the sheets. The air gap protects the reflectivity of the inner surfaces of the sheets, thereby preserving the ability of the sheets to reflect radiant heat. The larger, lower sheet can be formed in a single catenaries from edge to edge of the sheet, or in a multiple array of catenaries to form parallel, tubular air gaps (26), if desired. The heat insulator can be mounted to fibrous insulation (22) or to other more rigid structures, if desired, when placed in a roof structure.

Abstract: Radiant heat reflective cell blanket (10) is formed with superposed support sheets (12 and 13) that form an array of cells thereover. A dead air space is maintained in each cell, and heat reflective sheets (20 and 21) are located within each cell. The reflective sheets (20 and 21) are adhesively connected to the upper and lower support sheets (12 and 13) to maintain a dead air space therebetween. The cells avoid the accumulation of dust, dirt, and fibrous material on the reflective surfaces of the blanket, thereby maintaining the reflectivity of the blanket, and the cells avoid outside contact by other objects that might reduce the reflectivity of the blanket.

Abstract: The blanket heat insulation with facing radiant barrier includes a heat insulation blanket assembly (10) that is to be placed in a wall structure of a building. The heat insulation blanket assembly includes a blanket formed of fibrous materials such as fiberglass, with the fibers being arranged in random array and defining air gaps therebetween for insulation purposes. Flexible sheet material (26) is positioned in superposed relationship with respect to a broad surface of the blanket (12), and includes a reflective surface (42) that faces the blanket. The fibers of the blanket engage and support the flexible sheet material without requiring an adhesive or other connection therebetween. This leaves the air gaps between the fibers of the blanket exposed to the heat reflective surface of the flexible sheet material, so that the air gaps tend to maintain the reflective properties of the reflective surface of the flexible sheet material.

Abstract: Roof insulation applicator (10) for applying sheet material to the roof of an industrial building includes a carriage (12) for mounting on adjacent purlins (14 and 15) of a partially completed roof. Support roller (40) is applied by the carriage to the upper surfaces of the purlins (14 and 15) and the carriage is tiltable about the support roller (40). The center of gravity of the carriage (12) is applied rearwardly of the support roller (40). Purlin engager (60) is mounted to the front of the carriage and engages under the upper laterally extending flange (22) of the purlin (14) and limits the downward pivoting of the rear end of the carriage applying a lever arm effect by the weight of the rear portion of the structure to the support roller (40). This firmly holds the sheet material in its stretched configuration extending from the roof panel (16) out to the support roller (40), reducing the tendency of the sheet material to sag in between the adjacent purlins.

Abstract: A heat block (28) is positioned between the upper lateral flange (24) of a purlin (14) and the roof panel (16) supported by the purlin. The heat block is in the shape of a barbell in that it includes opposed side portions (33 and 34) that are sized and shaped to extend laterally beyond the purlin (14) out into the hot zone adjacent the upper portion of the purlin and the roof panel (16). The heat block is of greater stiffness than the adjacent blanket insulation so that the heat block reliably occupies the space in the hot zone. Phase change material (64) can be incorporated in the opposed side portions (33 and 34) of the heat block.

Abstract: Heat insulation blanket (10) includes a layer of inner cells (16) containing a phase change material, and opposed outer cells (18 and 19) containing dead air or other undisturbed gas. When placed in an attic or other insulated area, the phase change material changes phase when the outside atmospheric temperature passes the phase change temperature, resulting in a delay in the transfer of heat between the interior space and the atmosphere because of the heat required for or given up by the PCM during its change of phase. The outer plies of sheet material that form the superposed cells of the cell blanket are formed with a coating of heat reflective material that faces the interior of the cell blanket, whereby the reflective surfaces are protected against deterioration and retain their capacity to reflect radiant heat.
