摘要： Laminated panels are made in a process whereby a starting foam formulation is processed through a mixhead, passed through a branched distribution system and dispensed through multiple outlets of the distribution system to produce a foam layer on a bottom facing layer. The foam layer is monitored for the presence of surface bubbles. When surface bubbles are observed, the backpressure in the mixhead is increased to reduce or eliminate the surface bubbles. An apparatus for performing the process includes an adjustment means at or upstream of a first branch point in the distribution system to increase or decrease the backpressure in the mixhead.

摘要： A foam roofing underlayment is provided with a reinforcement membrane having an array of fastener elements for engaging fastener elements on a flexible roof membrane. The underlayment is formed by molding foam between the reinforcement membrane and a carrier membrane. The underlayment in secured to the roof using washers having fastener elements for engaging the fastener elements of the flexible roof membrane. An anti-peel flap with fastener elements is provided around the periphery of the washers. A slip sheet is used between the underlayment and the flexible roof membrane to permit accurate positioning of the flexible roof membrane prior to engagement of the fastener elements. The interstices between the fastener elements provide lateral moisture paths to vents in the flexible roof membrane.
