ROOF INSULATION STRUCTURE AND METHOD OF MAKING SAME

摘要

A ROOF INSULATION STRUCTURE AND METHOD OF MAKING SAME A roof insulation structure and method of making the structure for greatly improving the insulation quality of a metal building roof. The structure includes a self-supporting medium density thermal insulation blanket having elongated slits and notches in the top thereof so that the blanket can be folded into a "U" shaped configuration. The "U" shaped blanket is received on the top and the sides of a pair of adjacent and parallel roof purlins and spans the width therebetween he "U" shaped configuration of the blanket provides means for receiving a thick blanket of low density thermal insulation inside thereof and between the purlins for increasing the insulation "R" factor of the insulated roof.
