The present disclosure relates to silicone-coated mineral wool insulation materials, methods for making them using specific coating methods, and methods for using them. One aspect of the disclosure is a method for making a silicone-coated mineral wool, the method comprising: providing a mineral wool comprising a collection of mineral wool fibers; applying to the mineral wool a solvent-borne coating composition comprising a silicone, the silicone of the coating composition having a number-average molecular weight of at least 25 kDa; and allowing the solvent to evaporate to provide silicone-coated mineral wool.

The present disclosure relates generally to an insulation-retaining sheet, e.g., for blown-in insulation, that includes an integral vapor-retarding membrane. In one aspect, the disclosure provides an insulation-retaining sheet including a sheet of mesh having an air permeability of at least 200 cfm per square foot; and one or more strips of vapor-retarding membrane, the one or more strips of vapor-retarding membrane being laminated to the sheet of mesh, the first side edge each of the strips of vapor-retarding membrane extending to the first side edge of the sheet of mesh, the second side edge each of the strips of vapor-retarding membrane extending to the second side edge of the sheet of mesh, wherein the insulation-retaining sheet has a plurality of open zones extending laterally from the first side edge of the sheet of mesh to the second side edge of the sheet of mesh in which no vapor-retarding membrane is laminated to the mesh.

A method of producing a foam is disclosed. The method includes providing an epoxy-containing compound, a cationic catalyst, an optional blowing agent, and at least one additive. The method further includes combining the epoxy-containing compound with the cationic catalyst, the optional blowing agent, and the at least one additive, wherein the epoxy-containing compound and the cationic catalyst react to polymerize the epoxy-containing compound to provide the foam having a density from about 0.3 lbs/ftto about 5.0 lbs/ftas measured by ASTM D1622. Further disclosed are the foam and a method for installing the foam.
