NEW OXFORD, Pa. — Environmentally Safe Products Inc. (ESP), maker of patented ESP Low-E® Reflective Insulation, recently 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. The result: contractors save the time and materials costs associated with installing that additional layer, and consumers have access to a new, affordable energy upgrade for their homes.
