since in dry kiln construction, multiple layers of dif-ferent materials exist in series; for example, gas, alu-minum, urethane foam, aluminum, and gas. (Note: To a lesser degree, parallel layering may be used.) The more useful coefficient is the overall heat transfer coefficient U, defined by The coefficient U is very often expressed as anR value,
