Skylight with curb design

Abstract

A skylight assembly includes a curb which supports the skylight above the roof surface. The curb is formed from four mechanically connected structural insulated panels. The panels include an outer fastener-receiving member such as OSB with an intermediate polystyrene foam layer and an innermost melamine layer. The curb is assembled on site and fastened to the roof structure with brackets. The melamine surface provides a finished interior surface and the curb itself provides thermal insulation.

1 . A skylight curb comprising four structural insulated panels connected to each other at four corners;
 each panel comprising an outer fastener-receiving layer adhered to an inner rigid foam layer bonded to an innermost layer having a finished surface;   each corner formed from interconnected first ends of one of said SIPs mechanically fastened to second ends of one of said SIPs wherein said first ends include an extended portion of said fastener-receiving layer extended beyond ends of said insulated layer and said finished layer, said second ends including fastener-receiving inserts adjacent an end of said insulated layer;   mechanically fastened fasteners extended through said extended portion into said insert forming corners having 90° angles.   
   
   
       2 . The curb claimed in  claim 1  wherein said finished surface comprises a polymer. 
   
   
       3 . The curb claimed in  claim 2  wherein said polymer comprises melamine. 
   
   
       4 . the curb claimed in  claim 1  wherein said fastener-receiving surface comprises wood. 
   
   
       5 . The curb claimed in  claim 4  wherein said fastener-receiving surface comprises particleboard. 
   
   
       6 . The curb claimed in  claim 4  wherein said fastener-receiving surface comprises OSB. 
   
   
       7 . The curb claimed in  claim 1  wherein said insulation layer comprises foamed polystyrene. 
   
   
       8 . The curb claimed in  claim 1  wherein said insert comprises wood. 
   
   
       9 . The curb claimed in  claim 1  wherein the frame is fixed to a roof substrate by brackets. 
   
   
       10 . The curb surface claimed in  claim 9  wherein flexible flashing is fixed to a top edge of said curb and an outer section of said curb and along said bottom edge of said curb. 
   
   
       11 . the structure claimed in  claim 10  further comprising a skylight fixed over said flashing. 
   
   
       12 . A skylight assembly comprising four separate curb members each curb member comprising an outer fastener-receiving layer adhered to a rigid foam layer, in turn adhered to an inner finished layer;
 said panels assembled together at four corners;   each corner formed from interconnected first ends of one of said SIPs mechanically fastened to a second ends of one of said SIPs wherein said first end have an extended portion of said fastener-receiving layer extended beyond ends of said foam layer and said finished layer and wherein said second ends have fastener-receiving inserts adjacent an end of said foam layer wherein said four panels are assembled together at 90° angles;   said curb fastened to a roof surface with a plurality of L-brackets fastened to said fastener-receiving surface of said curb members;   a flexible plastic flashing member surrounding said curb member;   and a skylight assembly fastened to an upper edge of said curb member.
