Abstract: A laminated building sheathing comprises a rigid foam board and a facer. The rigid foam board comprises a drainage pattern formed on a major surface of the foam board. The drainage pattern comprises a drainage channel. The facer is configured to cover the major surface of the rigid form board and to essentially conform to the drainage pattern. The facer is semi-permanently bonded to the drainage channel but permanently bonded to non-channel planar portions of the major surface.

Abstract: The presently disclosed technology provides a composition and method for producing a thermally stable, rigid polyurethane and/or polyisocyanurate foam by reducing or eliminating the presence of alkali metal components and/or alkali earth metal components, thereby producing a foam, which under fire conditions, will at least maintain its volume or intumesce or not reduce its volume by more than about 30%. The presently disclosed technology allows for a reduction in alkali and/or alkali earth metal components in foams that meet current standards with reduced fire retardant loadings. The presently disclosed technology further provides foams with lower alkali and/or alkali earth metal components which may be made to increase in volume under fire conditions.

Abstract: A rigid closed cell polyisocyanate-based foams is created by reacting at least one organic polyisocyanate with compounds having at least two active hydrogen atoms in the presence of an n-pentane blowing agent. When the foam is formed into a laminated board with facers, the foam formulation includes a sufficient amount of a common blend of cleaning solvent chemicals to cause a noticeable improvement in facer adhesion. The chemicals used to improve facer adhesion are a standard blend of industrial cleaning solvents called nullDi-Basic Estersnull or DBE. The actual chemical compounds in one mode of this mixture are the methyl esters of about 59% glutaric acid, about 20% succinic acid, and about 21% adipic acid. The minimum rate of addition of the Di-Basic Estersnull nullDBEnull thought to be effective may be less than about 0.5 parts per hundred parts of polyol (pphpp). The currently preferred embodiments use add-on rates within the range of about 0.5 to about 5.0 pphpp, with the currently most preferred range being from about 1.0 to about 3.0 pphpp. The blend of cleaning chemicals employed by the present invention surprisingly enhance the adhesion between the foam and the facer.
