Abstract
An insulated foam board is manufactured by leading a first facing from a reel and laying down liquid foam reactants. A second facing from a supply reel is laid over the reactants forming a sandwich. The foam is expanded in an oven and the board is cut to a desired length. One or both facings are removed and re-wound onto a reel for re-use. A coating in the form of a metallized paint is applied in-line to one or both faces of the foam core, after removal of the facings. The painted boards have enhanced heat insulation properties.
