A sound-deadening laminate, comprising a structural skin having a first face; and a layer of sound-deadening material, wherein the material has an equivalent Young's Modulus between 50 and 600 psi and is attached to the first face of the structural skin to form a laminate structure. The sound deadening laminate may be attached to framing members of a building.

Combination sound-deadening board

Building component assemblies include a sound-deadening board having defined compressional stiffness positioned between a framing member and an assembly board.

Lightweight sound-deadening board

A single ply membrane roofing system includes a roofing insulation board which, preferably, is at least 45% by dry weight expanded perlite. One major surface of the insulation board is coated with a latex coating comprising, by dry weight, between 48.3% and 96% clay; between 3.1% and 33.3% latex; and between 0% and 34% sodium silicate. A single ply roofing membrane is adhered to the coated major surface of the insulation board with a roofing contact adhesive.

Coated roofing insulation and roofing systems including such insulations

An insulation board suitable for use as a roof insulating board has a density between about 8 and about 15 pounds per cubic foot; a MOR/density ratio of at least 10.5 to 1 and includes, by dry weight, between about 45% and about 76% expanded perlite; between about 15% and about 45% cellulosic fibers; between about 0.1% and about 10% latex binder; between about 2% and about 9% bituminous material; and about 0% to about 3% alum.
