The present invention establishes an insulation cavity by connecting rail tracks to the roofing panels, slidably engaging adjustable suspension clips within said tracks, and connecting ceiling panels to the depending end of the suspension clips. The suspension clips are slidable within these track connections to allow the relative displacement between the roof and the depending ceiling. This freedom allows flexability in the alignment of the ceiling panels in relation to the roofing panels and thereby simplifies installation procedures. Further, the deliberate thermal isolation of the connected roof and ceiling panels promotes the relative displacement therebetween due to thermal expansion and this displacement translates to potentially damaging strain within the roofing system in the absence of the freedom provided by the clip to track engagement. It is preferred that the suspension clips be adjustable with respect to the distance between the roof and the suspended ceiling in order to accomodate differing desired insulative materials and differing desired thermal resistance. The disclosure teaches connection means that are quickly and easily engagable to the underside of the roofing panels and to the top side of the ceiling panels, are installable without special tools, and do not require that any holes be passed through the shelter portion of the roofing panels.
