An insulation product is comprised of a fibrous layer pre-assembled with a flexible foam layer. The layer containing the fibrous material may comprise a fiberglass layer or a layer containing cellulosic fibers. The foam layer, on the other hand, may comprise any suitable flexible foam, such as an elastomeric polyurethane foam, that creates an air barrier. The two materials are laminated together and the resulting product is delivered to a building or structure f or installation. |
