Insulation assemblies for roofing and method of installation

Abstract

A ridged insulation board assembly that is comprised generally of a ridged insulation board and an additional structural element that has been pre-installed in or onto the surface of the insulation board. The assembly is installed onto a support surface such as roof deck without separate stress plates.

1 . An insulation board assembly for use in roof construction and repair comprised of a ridged insulation board and at least one additional pre-installed structural element having sufficient pull through resistance to permit securement by a fastener.  
   
   
       2 . The insulation board assembly of  claim 1  wherein said pre-installed structural element is a plurality of spaced stress distribution plates.  
   
   
       3 . The insulation board assembly of  claim 2  further comprising a matrix of plates.  
   
   
       4 . The insulation board assembly of  claim 1  wherein said pre-installed structural element is a reinforced facer layer.  
   
   
       5 . The insulation board assembly of  claim 4  wherein said layer has a plastic or polyurethane composition.  
   
   
       6 . The insulation board assembly of  claim 4  wherein said facer layer substantially covers the entirety of a surface of the board.  
   
   
       7 . The insulation board assembly of  claim 1  wherein said pre-installed structural element is a lattice-type reinforced facer layer.  
   
   
       8 . The insulation board assembly of  claim 1  wherein said assembly is fastened to a surface using large diameter head fasteners such as structural insulated panel (SIP) fasteners.  
   
   
       9 . The insulation board assembly of  claim 1  wherein said assembly is further secured to a metal decking layer.  
   
   
       10 . The insulation board assembly of  claim 1  wherein said pull through resistance is greater than 500 lbs.  
   
   
       11 . A method for installing insulation board in roof construction comprising: 
 providing an insulation board with a pre-installed arrangement of stress distribution plates;    placing said insulation board on said decking; and    installing fasteners through said stress distribution plates to secure the insulation board to said decking.    
   
   
       12 . A method for installing insulation board to a structure comprising: 
 providing an insulation board with a pre-installed reinforcement layer that defines having a grid which defines preferred fastener positions;    placing said insulation board on said decking; and    installing fasteners at said positions to secure said insulation board to said decking.
