ABSTRACT:
A method of installing insulation under a pre-existing roof of a building of a type having a spaced apart structural beams standing in one direction under the roof and a plurality of spaced apart elongated purlins extending transversely to the structural beams and being supported by the structural beams. Purlin clips are used which connect to the purlins at the top and to a lower support member at the bottom thereof. The method includes installing an upper support member across from one to the other of an adjacent pair of purlins. An upper strip of insulation is positioned between adjacent pairs of purlins above the upper support member whereby the strip of insulation will be supported by the upper support member. A lower strip of insulation is attached at one end into one of the structural beams, under the upper layer of insulation, and to the other of the structural beams at the other end thereof. A lower support member is then attached between adjacent purlin clips and under the lower strip of insulation for supporting the under side of the lower strip of insulation. The upper support member or members are then removed so that the upper strip of insulation will move down and be supported on top of the lower strip of insulation.
