The sum of all “R values” is: .70 + .10 +. 038 + .10 = .938 This would NOT be an acceptable combination of material for the hearth extension since the total calculated “R value” of the materials used is under the required “R value” of 1.19. An additional layer of insulating materials must be used. -
