Insulated glazed roofing system

Abstract

A glazed roof structure which is suitable for forming a room that can be used year round includes a plurality of rafters with supporting insulating panels. The insulating panels have a foam core with upper and lower plastic or metal skins. These are supported by the rafters with upper and lower glazing beads and in effect are free floating panel structures supported on the roof. The foam panels have sufficient structural strength so that they do not bend and cause leakage in use.

1 . A glazed roof structure comprising: 
 a plurality of rafters;    roofing panels supported between two adjacent rafters said panels resting between upper and lower glazing beads on said rafters;    said panels comprising a foam core having upper and lower skins; and    wherein said skins form water tight seals between said upper and lower glazing beads by compression between said upper and lower beads and said panel.    
     
     
         2 . The glazed roof structure claimed in  claim 1  wherein first and second ends of said rafters are supported by upper and lower beams.  
     
     
         3 . The glazed roof structure claimed in  claim 2  wherein a plurality of rafters extend radially outward from a central point and support a plurality of said panels between adjacent rafters.  
     
     
         4 . The glazed roof structure claimed in  claim 1  wherein said panels have a thickness greater than 1″.  
     
     
         5 . The glazed roof structure claimed in  claim 1  wherein said panels have a thickness of at least 1.5″.  
     
     
         6 . The glazed roof structure claimed in  claim 1  wherein said roof is a conservatory style roof.
