In the past, several mathematical approaches have been used to determine the thermal efficiency of ordinary concrete blocks. In 1989, the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) published in their Fundamentals Handbook their accepted method of calculating the Overall R – Value of Masonry Walls. This method is also known as the Isothermal Planes method.This report covers the thermal efficiency of masonry units factory insulated with ICON Universal Inserts using the Isothermal Planes method.
