Abstract
A thermally insulating structural laminate comprising a core of rigid plastic foam having two major surfaces, at least one of the major surfaces of the foam being attached to a facer comprising a fribrous sheet having at least one layer of an air- and moisture-impervious polymer disposed on the inner surface thereof and interposed between the fibrous sheet and the foam, the oxygen transmission of the polymer being a value of less than about 1 cc/100 in.sup.2 -24 hrs-atm sufficient to make the facer substantially impervious to the passage of air and water vapor, resulting in the long-term preservation of insulation value.
