These materials have a typical R-value of about R-5 to R-6 per inch, though when installed with a radiant surface (that might help) and a 3/4" air gap, the R-value is increased substantially - as we detail below. Fiberglass batts, which are still most-widely used in residential con...
Foams made from alkenyl aromatic polymers (e.g, polystyrene) or polyolefin polymers (e.g. polyethylene and polypropylene) have found extensive use, particularly as packaging, protective, and insulating materials. Polyolefin foams are particularly advantageous due to their tolerance to high service temper...
25. A gasket as described in claim 18 wherein the binder is selected from the group consisting of: butadiene acrylonitrile, carboxylated acrylonitrile butadiene, styrene butadiene, carboxylated styrene butadiene, polychloroprenes, polyvinylidene chloride, polystyrene, polyvinyl chloride, fluornated ethylene ...
(845 m2/m2) and the wood batt insulations demonstrated the biggest differences of smoke production, with a 32 times higher value for the expanded polystyrene. Ostman [21] noted that during combustion, wood releases smoke at a quantity of 25–100 m2/kg, which is far less than synthetic ...
