New Oxford, PA — Environmentally Safe Products Inc. (ESP), maker of patented ESP Low-E® Reflective Insulation, has announced that its Therma Sheet roofing underlayment has been certified by the International Code Council Evaluation Service (ICC-ES). The designation means Therma Sheet meets the code requirements of a stand-alone roofing underlayment for the building industry.
Previously, code required roofers to install Therma Sheet over a layer of felt paper or other underlayment. The ICC designation confirms that Therma Sheet offers superior performance without any other underlayments.
“We welcomed the rigorous testing of Therma Sheet performed by the ICC,” says Tom Wright, ESP’s Chief Operations Officer. “The resulting certification means that roofers across the U.S. can save time money while homeowners enjoy the benefits of the leading reflective insulation underlayment.”
Therma Sheet insulation is constructed of 99 percent pure polished aluminum facings, heat laminated to a closed cell polyethylene foam core. This patented process makes Therma Sheet a thermal and moisture barrier under metal roofing, stone coated steel, concrete, clay tile and more.
