SYSTEM FOR RETROFITTING AND ENHANCING THE THERMAL RESISTANCE OF ROOFS AND WALLS OF BUILDINGS

摘要

An insulating system for retrofitting the roof and/or walls of a building. The retrofit system includes a first layer of insulating material extending transverse to the purlins, girts and chords and atop the existing roof or wall structure as well as a plurality of longitudinally extending bridge members each with an upper and a lower surface. The system also includes a plurality of orthogonally extending spacer members that compresses the first layer of insulating material proximate to the spacer members and allowing an otherwise uncompressed first insulation layer to span between the spacer members. The system further includes a second layer of insulation extending across the upper surface of the bridge members wherein a plurality of panel clips each with a panel clip tab are disposed atop the second layer of insulation and are fastened to the bridge member and the clip tabs engage with the lateral edges of the roof or wall panels in the formation of a water resistant seam.

1. An insulating system for retrofitting the roof or walls of a building, the retrofit insulating system comprising:
an existing roof or wall structure; a first layer of insulating material extending transversely across the existing roof or wall structure a plurality of bridge members each with an upper and a lower surface; a plurality of spacer members each with an upper flange, a lower flange and a spanning member disposed between and connecting the upper and lower flanges, the upper flange of the spacer members secured to the lower surface of the bridge member wherein the spacer member extends downwardly to the lower flange and the lower flange is disposed atop and locally compresses the first layer of insulation proximate the lower flange and the lower flange is secured with fasteners to at least the existing roof or wall structure; a second layer of insulating material extending transversely across the upper surface of the bridge members; and a plurality of panel clips each with a base and a panel clip tab disposed opposite the base, the panel clips disposed atop and locally compressing the second layer of insulation, wherein a fastener is passed through the base of each of the panel clips, through the second layer of insulation, through the bridge member and into the upper flange of the spacer member, the panel clip tabs engaging with the roof or wall panels in the formation of a water resistant seal.
