Publication number: 20160305126Abstract: According to one aspect, a roofing system comprises a plurality of insulation boards adapted for overlying a roof deck to form a layer of insulation. Each of the plurality of insulation boards has opposing planar surfaces and has a facer on at least one planar surface, and each of the plurality of insulation boards comprises polyisocyanurate foam having a first polyisocyanurate foam density. The roofing system further comprises a plurality of cover boards adapted for overlying the layer of insulation. Each of the plurality of cover boards has opposing planar surfaces and has a facer on at least one planar surface, and each of the plurality of cover boards comprises polyisocyanurate foam having a second polyisocyanurate foam density greater than the first polyisocyanurate foam density. The greater polyisocyanurate foam density provides for a compressive strength to resist deformation.Type: ApplicationFiled: June 27, 2016Publication date: October 20, 2016Inventors: Walter Alexander Johnson, Joel Evan Hazy, Duane Paradis, Christopher J Griffin, Raymond C Swann, Brad C Burdic

Publication number: 20150225881Abstract: According to one embodiment, a method of forming a facer includes forming a first layer of nonwoven glass fibers and positioning a second layer of reinforcement fibers atop the first layer of nonwoven glass fibers. The method also includes coating the first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers with a binder composition and pressing the first layer of nonwoven glass fibers and the second layer of reinforcement fibers together between a pair of rollers. The binder composition is then dried to couple the first layer of nonwoven glass fibers and the second layer of reinforcement fibers to form the facer. The first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers are free of a material coating prior to coating of the binder composition.Type: ApplicationFiled: February 11, 2014Publication date: August 13, 2015Applicant: JOHNS MANVILLEInventors: Duane Paradis, Guodong Zheng, Jawed Asrar
