Filed:

Feb 18, 2003

Appl. No.:

10/369409

Inventors:

Robert E. Fligg - West Des Moines IA 50265

International Classification:

E04G 2100

US Classification:

5274611, 5274506, 524073, 524074

Abstract:

There are advantages to installing roof insulation in industrial and commercial buildings from above, rather than from below after the roof is sealed. A reinforced facing sheet is used that is rolled out between purlins. This facing material is used to support the insulation from below. The facing sheet is anchored to reduce pillowing of the insulation. The anchoring system for the facing material comprises a metal angle, firmly affixed to the top of a rafter between purlins. The facing material is sandwiched between the angle and the rafter, and anchored. A channel-shaped lower support member is located beneath the facing material and the angle is pressed, from above, into the open part of the channel shape as it is situated on top if the rafter. Consequently, the facing material is also pressed into the lower support member, thus holding the facing material at the correct elevation.

Abstract:

There are several advantages to installing roof insulation in industrial and commercial buildings from above, rather than from below after the roof is sealed. A reinforced facing sheet is used that can be rolled out between the purlins that support the steel roofing. This reinforced facing material is located at the bottom of an insulation system and is used to support the insulation from below. The reinforced facing sheet must be anchored to reduce pillowing of the insulation and provide a neat appearance to the insulation job. The anchoring system for the reinforced facing material is made up of a metal angle that is firmly affixed to the top of a rafter between purlins. The reinforced facing material is, thus, sandwiched between the angle and the rafter top, and securely anchored, there. A channel-shaped lower support member, usually vinyl, is located beneath the reinforced facing material and the angle is pressed, from above, into the open part of the channel shape as it is situated on top if the rafter. Consequently, the reinforced facing material is also pressed into the lower support member, thus holding the reinforced facing material at the correct elevation.

Inventors:

Robert E. Fligg - West Des Moines IA

International Classification:

E04B 162

US Classification:

5274212

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.

International Classification:

E04B 162

US Classification:

52743

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.
