  • Patent number: 7316099
    Abstract: The present invention is a spaced sheathing roofing system and method in which roof cladding is placed onto batten strips positioned on roof rafters. The roof cladding is attached using an adhesive. The attachment component is preferably a polymer adhesive, more preferably a polyurethane, for adhering the roof cladding. The adhesive is preferably sprayed onto the lower surface of the placed roof cladding while also being sprayed onto the batten strips and the supporting truss rafters. The sprayed adhesive bonds the adjacent roof cladding together and also bonds the roof cladding to the batten strips to form a monolithic structure. In addition, the sprayed layer of adhesive forms an insulative layer while also forming a waterproof barrier.

  • Patent number: 6130268
    Abstract: A two component polyurethane adhesive and a method of bonding construction materials to various construction substrates. The adhesive being the reaction product of two separate components that are mixed together immediately prior to application upon dispensing onto a substrate. The first part of the adhesive, referred to as the "A-side," may be either an NCO terminated prepolymer or a polymeric MDI (methylene diphenyl diisocyanate). The second part of the adhesive, referred to as the "B-side," is a blend of rigid, elastomeric, and flexible polyols and extenders. The adhesive formed by mixing the A-side and B-side components, is a frothing foam that has a consistency such that it does not run or drip when applied to the substrate, that expands upon application to the substrate surface to fill voids or imperfections, that collapses when the material to be bonded is placed in contact with the adhesive, and that has a rapid cure time.

  • Patent number: 5723534
    Abstract: A two part polyurethane adhesive system and method of using the adhesive to bond polyurethane foams, polystyrene foams, and other substrates. The first part of the adhesive system is a hydrophilic polyurethane prepolymer prepared by reacting a high molecular weight, multi-functional polyol which has been copolymerized randomly from propylene oxide and ethylene oxide, with a diisocyanate or polyisocyanate. This reaction mixture is then diluted with either a flame retardant, a plasticizer, a solvent which is not considered a volatile organic compound, or a combination of these chemicals. The second part of the adhesive system is an aqueous phase curing agent. In addition to water, the components of the aqueous phase may include a tackifying agent or a catalyst or both.

  • Patent number: 5362342
    Abstract: A method of bonding a roof tile to a roof substrate utilizing a two component polyurethane foam. The method includes the step of applying under low pressure a stream of a two component foamable liquid polyurethane on a roof substrate. Preferably, the foamable liquid polyurethane has a density in the range of about one and one-half to about two pounds per cubic foot and a reactivity period in the range of about one and one-half to about four minutes. Preferably, the foamable liquid polyurethane is applied at a rate of about two to about three pounds per minute. The roof tile is placed into contact with the foamable liquid polyurethane during the reactivity period of the foamable liquid polyurethane.
