Abstract: An arrangement and system is provided for creating a sloping roof out of a flat roof and also of providing said sloping roof with slopes which merge into plateaus.This roof has been so designed that it consists of a plurality of insulation blocks or sheets, some of which may be tapered and some of which may be provided with plane surfaces and the uppermost elements of the courses of insulation sheets are of laminated construction consisting of a styropore block which may be either tapered or of plane configuration, and these blocks are of laminate construction with a substantially 1/2" fiberboard. As is well-known in this art, the usual insulation block or sheet may be formed of styrofoam which will not accept an adhesive, and the heat from hot tar or the like which may be used in the construction of roofs may cause the styrofoam insulation sheets to disintegrate. Styropore blocks will not be affected by the heat generated by hot tar applications to the roof.

Abstract: A vulcanizer and method for vulcanizing sheets of unvulcanized elastomeric material is presented in which the sheets are formed from generally rectangular small sections of unvulcanized material where the edges of the sections are tapered and mated together along their maximum dimension to form longitudinally extending seams within large sheets. The sheets are wrapped onto a series of concentrically assembled mandrels having different diameters, which serve as individual supports for the multiple wraps of sheet material. Each mandrel is received within the mandrel of the next larger diameter and is supported within the vulcanizing chamber by self-supporting mounting devices or carriage.

Abstract: A roofing structure is disclosed having a layer of blocks of insulating material supported on a roof deck and featuring a hermetic seal encapsulating a limited part of the insulating material layer and which completely envelopes selected insulation blocks covering at least portions of the deck periphery to effect wind uplift resistance.

Abstract: A roofing structure including a plurality of abutting fireproof sections and a reservoir board having apertures therein, the reservoir board mounted on and secured to the sections of the fireproof member. Insulation mounted on said reservoir board and covering said apertures therein. In the event of a fire in the building covered by the roof, the insulation will become molten and under normal circumstances would flow on to the fireproof member and leak therefrom at the seams between abutting sections of the fireproof member and flow therethrough downwardly of the roof. This molten insulation would serve to intensify the fire within the building. Indicia is provided on the reservoir board to aid in the proper installation thereof so that the apertures therein will not be positioned above the seams in the fireproof member. In a modification of the invention the reservoir board is eliminated and the fireproof member is provided with a plurality of cups formed therein to receive and to hold the molten insulation.

Abstract: A roofing installation is disclosed having a unique construction particularly suited for minimizing certain major costs and labor relating to roof installation. A plurality of substrates are provided including a deck and a course of insulation blocks supported by the deck. An upper roof surface is provided by a flexible sheet membrane secured to a substrate underlying the membrane. Adhesive means are applied in a predetermined pattern to provide adhesively sealed areas between the flexible membrane and its underlying substrate while additionally providing selected zones between the membrane and its underlying substrate completely free of adhesive means. The adhesively sealed areas are in overlying, lapping relation to the perimeters of the insulation blocks to provide a roofing seal of high integrity which minimizes undesired air infiltration through joints between abutting insulation blocks and any apertures or holes created by fastener installation for securing roof substrates to the roof deck.

A plurality of spot bonding pads and the composite board are covered respectively with a flexible membrane cover and with a roofing membrane which is flexible and preferably formed of rubber. The cover extends over each spot bonding pad and is adhesively secured thereto, the cover extending beyond the edges of the spot bonding pad and such extensions of the cover are adhesively secured to the flexible membrane. Each spot bonding pad is adhesively secured to the flexible membrane. A screw extends through the cover, the spot bonding pad, the membrane, the composite board, the insulation and the remaining roofing elements.

Abstract: A roofing construction wherein a plurality of blocks of insulation are loosely laid on a roof deck in abutting relation. So-called "flat roofs" are conventionally provided with an inclination to the horizontal so that water will naturally flow from the roof. The aforesaid insulation blocks are preferably of oblong shape and are laid longitudinally with respect to the direction of the natural water flow on the roof so that the longitudinal abutting edges of the insulation blocks produce a seam which is parallel to the natural flow of the water from the roof, and the inclination thereof. A furring strip of either wood or metal is applied over each longitudinal seam between adjacent blocks and this strip is secured firmly by means of screws or other fastening devices which extend through the strip and into the roof deck so that in effect the adjacent insulation blocks are clamped between the furring strip and the metal roof deck.

Abstract: An extruded aluminum termination bar adapted for use on roofs for securing the flexible roof membrane in proper position and for securing a metal facing to the membrane where such membrane extends a distance down the side of the roof. The termination bar being reversible, one side being outermost when the bar is utilized for securing the above mentioned metal facing in place and the other side of the termination bar being usable for application to the membrane for holding it in place on a parapet. This side of the termination bar being usable when the membrane extends upwardly a distance along a parapet which extends above the body of the roof.

The other side of the termination bar providing ribs along one longitudinal edge of the body and also providing ribs along the longitudinal edge of the flange.

Abstract: A system of automatically transferring vacuum uplift on the top of a roof to the underneath side of the roof membrane to shift the uplift pressure forces into the roof insulation and decking rather than on the roof membrane to prevent upward movement of the membrane and roof layer. A roof structure provided with one or more oneway or duckbill valves placed 3 feet in from the perimeter and on every outside corner at 50 foot intervals, which at their bases open into the area between a loosely laid membrane and the roof insulation in order to equalize the positive air pressure between the loosely laid membrane and the insulation with the minus air pressure which occurs on the top of the roof when wind blows across the roof.

Abstract: A taped and double cemented or glued rubber joint for use in connecting together the lapped cemented ends of adjacent cured rubber membranes in a roof construction, and for giving protection thereto. The lapping ends of the cured rubber membranes are sealed together by means of cement or the like, providing an adhesive contact system sealing the seam between adjacent membranes. An additional sealing means is provided which is premade and is adapted to be caused to adhere to both portions of both of the overlapping adjacent rubber membranes. This tape or additional sealing means is a composite structure and is applied over the seam between adjacent membranes providing double sealing structure and the tape comprises a lower uncured gum rubber strip which is applied over a portion of one rubber membrane which laps over a portion of the other rubber membrane and also includes a portion which extends over and is cemented to a part of the other membrane and adjacent to the end edge of the rubber membrane.

Abstract: A roof, or the like, composed of a plurality of blocks of relatively rigid insulating material which may be formed of Styrofoam. The relatively rigid blocks of insulating material being so configured that adjacent blocks will mate together forming a sealing means for the roof, or the like, which constitutes, in effect, a hermetic seal to thereby eliminate the possibility of temperature, moisture, etc. from entering between the blocks. The concept also involves the method of laying the plurality of blocks, whereby the sealing between adjacent blocks is aided by what I shall term an "UP" and "DOWN" arrangement of alternate blocks. The medium, which is rigid insulation, is intended to be used to form the insulating blocks will not accept adhesive so that a rubber or plastic sheet may not be caused to adhere to these relatively rigid insulating blocks when laid thereover.
