Abstract
A support grid (10) for roof insulation in a metal building having a roof (12) with a plurality of substantially identical, spaced purlins (16). The support grid includes at least one cross member (26) adapted to extend between adjacent purlins (16). The cross member (26) rests on and is supported by a flange (22, 24) of a first purlin (16) and the upper flange (22) of the adjacent purlin (16). At least one support member (46) may extend longitudinally at angles to the cross members (26) and be engaged therewith. Preferably a first end (30) of the cross member (26) is adapted to rest on the lower flange (24) of a first purlin (16), and a second end (32) is adapted to be hooked, prior to the application of rigid roofing material (18) to the purlins, over the upper flange (22) of the adjacent purlin (16) toward which the lower flange (24) of the first purlin (16 ) extends. The method for insulating of the invention includes installing a support grid (10) on the purlins (16) of a roof (12) from above before the purlins (16) are covered by other parts of the roof (12). Selected insulation material (34) is then placed onto the support grid (10) from above to substantially fill the space…
