Abstract

A method of insulating the roof of a building by a strip of vinyl stretching a sheet of vinyl material between two structural beams of a building. A plurality of such sheets of vinyl backed fiberglass insulation are fastened side-by-side to each other to cover the area desired. Purlin clips are utilized to attach to purlin structural members extending across from one of the structural beams to the other and these are placed in a series of straight lines at predetermined intervals. These purlin clips have an aperture therein so that a band of metal can be threaded through each successive ones of the clips for the purpose of supporting the bottom side of the sheets of vinyl at even intervals along the length thereof. The adjacent edges of the vinyl sheets are positioned so that they will hang down and so that it can be separated by hand to permit loose insulation, such as chopped up fiberglass insulation to be blown between the vinyl sheets. After the entire area formed by the sheets of vinyl is filled, then the adjacent edges of the sheets of vinyl material are stapled together while in the such lower position thereof and then they are stuffed back up through the seam to a position above the vinyl sheets.

Dependent claims

A method of insulating under a pre-existing roof of a building of a type having a pair of spaced apart structural beams extending in one direction supported in the building under the roof thereof and a plurality of spaced apart elongated purlins extending transversely to said structural beams and being supported by said structural beams and utilizing purlin clips of a type having means on the top thereof for connection to a purlin and aperture means on a lower portion thereof for receiving a strip of metal;

said method comprising:
(a) attaching one end of a strip of backed fiberglass insulation approximately as wide as the distance between purlins along one end thereof to one of said structural beams;
(b) attaching the other end of said strip of backed fiberglass insulation to the other one of said structural beams;
(c) repeating steps (a) and (b) with a second strip of backed fiberglass insulation approximately the same size as the first said strip, wherein one side of the first said strip is adjacent to one side of said second strip, each of said strips having an edge of said strip hanging down in juxtaposition with respect to each other;
(d) repeating the steps of (a) and (b) using a third strip of backed fiberglass insulation approximately the size of first said strip, adjacent to said second strip wherein the other side of said second strip and one side of the third strip have an edge thereof hanging down in juxtaposition with respect to each other;
(e) attaching one of said purlin clips to each of said purlins which are disposed directly above the first said, second and third strips of backed fiberglass insulation wherein said purlin clips are in a straight line;
(f) threading a continuous one piece elongated band through the aperture means in each of said aligned purlin clips wherein said band will support the underside of the first said, second and third strips;
(g) extending a tube between the first and second strips;
(h) blowing loose insulation through said tube to position the loose insulation above said second strip;
(i) extending said tube between said second and third strips;
(j) blowing loose insulation through said tube to position the loose insulation above said third strip;
(k) fastening adjacent edges of the first and second strips together and tucking them up above the first and second strips to form an expansion joint;
and
(l) fastening adjacent edges of the second and third strips together and tucking them up above the second and third strips to form an expansion joint.
