20090056029Foam core article with flexible heat-resistant knitted fabric - A foam core article such as a mattress or pillow is covered on a surface with a flexible heat-resistant knitted fabric. Preferably a further sacrificial fabric also is used to allow passage of CPSC 16 CFR 1633 with a peak heat release of no more than 200 kilowatts in a 30 minute time period following ignition.03-05-2009
20090061717Foam core article with flexible heat-resistant knitted fabric - A foam core article such as a mattress or pillow is covered on a surface with a flexible heat-resistant knitted fabric. Preferably a further sacrificial fabric also is used to allow passage of CPSC 16 CFR 1633 with a peak heat release of less than 250 kilowatts in a 30 minute time period following ignition.03-05-2009
20090075033Building wrap for use in external wall assemblies having wet-applied facades - A multiple sheet building wrap for wrapping the structural components of a building in order to protect the underlying structural components from moisture is provided. The building wrap is particularly useful under facades such as wet applied stucco or engineered stone, demonstrating good drainage of liquid water and moisture vapor permeability. The building wrap is a composite of a water resistive barrier and a porous intervening layer which acts as a barrier to stucco as it is applied. An exterior wall construction incorporating such building wrap is also provided.03-19-2009
20090094754Foam core article with flexible heat-resistant knitted fabric - A foam core article such as a mattress or pillow is covered on a surface with a flexible heat-resistant knitted fabric. Preferably a further sacrificial fabric also is used to allow passage of CPSC 16 CFR 1633 with a peak heat release of no more than 200 kilowatts in a 30 minute time period following ignition.04-16-2009
20090158683Multiple sheet building wrap for use in external wall assemblies having wet-applied facades - A multiple sheet building wrap for wrapping the structural components of a building in order to protect the underlying structural components and optional building sheathing from moisture is provided. The building wrap is particularly useful under facades such as wet applied stucco or engineered stone, demonstrating good drainage of liquid water and moisture vapor permeability. The building wrap is a composite of a water resistive barrier, a three-dimensional mesh layer and a porous intervening layer which acts to filter the stucco as it is applied. An exterior wall construction incorporating such building wrap is also provided.06-25-2009
20110094826COMPOSITE LAMINATE FOR A THERMAL AND ACOUSTIC INSULATION BLANKET - This invention is directed to a composite laminate comprising in order (a) a flame retardant polymeric moisture barrier (b) an inorganic platelet layer and (c) a flame retardant thermoplastic film layer The invention is also directed to a thermal insulation and acoustic blanket comprising a core of fibrous material or foam surrounded by the above composite laminate wherein the thermoplastic film layer of the composite laminate contacts and encapsulates the core.04-28-2011
