Prepare an alkenyl-aromatic foam having good surface quality, high thermal insulating properties and low density using an extrusion method by expanding a foamable polymer composition of an alkenyl-aromatic polymer composition containing less than 20 weight-percent covalently bonded halogens and having a polydispersity of less than 2.5 and a water solubility greater than 0.09 moles per kilogram and 2.2 moles per kilogram or less at 130 degrees Celsius and 101 kilopascals pressure and 0.8-2 moles per kilogram of a blowing agent containing 0.4 moles per kilogram or more of a chlorine-free fluorinated blowing agents and water at a concentration of at least 0.22 moles per kilogram; wherein moles per kilogram are relative to kilograms of alkenyl-aromatic polymer. The resulting foam has a density of 64 kilograms per cubic meter or less and a thermal conductivity of 32 milliwatts per meter-Kelvin or less after 180 days.

Disclosed is a roofing system for a structure such as a building. The system comprises a roof deck; a plurality of panels of an extruded alkenyl aromatic polymer foam above and adjacent the deck; and a substantially waterproof membrane above and adjacent to the foam. The foam has from about 30 to about 80 percent open cell content. The foam provides excellent mechanical support for the membrane, and is water resistant. The foam further has a high heat distortion temperature, and is substantially free of distortion at high service temperatures encountered in roofing systems. Further disclosed is a recovery roofing system employing the above foam. Further disclosed are processes for constructing a new roofing system and a recovery roofing system.

Disclosed is an evacuated and unevacuated microcellular foam containing an infrared attenuating agent (IAA). The evacuated foam has an average cell size of about 70 micrometers or less. The unevacuated foam has an average cell size of 1. 0 micrometers or less. The IAA provide a greater proportional reduction in foam thermal conductivity in these foams than in foams of larger cell size. Further disclosed is a method of using the foams.

The present invention pertains to a multilayer foamed flooring and wall product. The inventive product is a resilient cushion foam flooring and wall product that is free of polyvinyl chloride (PVC), plasticizers and heavy metal stabilizer. The product is made of a multilayer top layer which is integrated with a latex or polyolefin polymer foam back layer. The product has particular utility in the heterogeneous flooring market and can be prepared using ordinary PVC melt processing equipment.
