摘要:
A roofing system includes a construction board positioned over a roof deck and a plurality of fastening plates positioned on a top surface of the construction board. At least one connector extends between two of the plurality of fastening plates and is positioned on the top surface of the construction board. The construction boards may be insulation or cover boards, and in certain embodiments may be polyisocyanurate boards. Fasteners are driven through the fastening plates and the construction boards and into an underlying roof deck to secure the construction boards in place.

A covered roof includes a roof deck, an insulation board, and a coverboard. The insulation board includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate cellular structure, has a density that is less than 2.5 pounds per cubic foot, and has a first planar surface and a second planar surface, each having a facer positioned adjacent thereto. The coverboard includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate cellular structure, has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, an iso index of at least 175, and a first planar surface and a second planar surface, each having a facer positioned adjacent thereto.

A high density construction board includes a cellular body having a first planar surface and a second planar surface. A first glass facer is positioned adjacent the first planar surface and a second glass facer is positioned adjacent the second planar surface. The cellular body of the construction board includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot.
摘要:
A method for producing polyisocyanurate insulation foams, the method comprising contacting an A-side stream of reactants that includes an isocyanate with a B-side stream of reactants that include a polyol and a blowing agent, where the blowing agent includes isopentane and n-pentane in a substantial absence of cyclopentane.
