<p>Large-area heat-insulating panels, interlocking on all sides, have top profiling, for fixture of covering panels, formed from a number of bars set in parallel top cutouts, and lie on rafters, to form an under-roof. The cutouts are U-shaped grooves (11') in which profile rails (54) can be laid. They are pref. 2-4 cm. deep, and fitted on the heat-insulating panels (10) at a vertical interval of 2-15 cm. Rails may be L-or U-sectioned, and perforated, and made from profiled extruded material. This permits exploitation of variable fixing intervals for roofing panels when the requisite bar height interval cannot be used.</p> |
