Geo-Synthetic Composite Insulation for Roofing

Abstract

A geo-synthetic composite insulation panel for roofing applications is provided. The panel comprises a bottom layer made of an insulating material and a top layer made from a geo-textile laminated on top of the bottom layer. The geo-textile material provides an absorption zone for any adhesive used to glue waterproof membranes onto the insulation panel. This allows a better redistribution of loads on the insulation panel and increases the resistance of the material to punctures that the surface of the waterproof membrane may be subject to. The material, by its nature, will enhance the whole integrity of the roofing system.

1 . A geo-synthetic composite insulation panel for roofing, comprising:
 a bottom layer comprising an insulating material; and   a top layer comprising a geo-textile laminated on top of said bottom layer.   
     
     
         2 . The geo-synthetic composite insulation panel according to  claim 1 , wherein said insulating material is a rigid insulating material. 
     
     
         3 . The geo-synthetic composite insulation panel according to  claim 2 , wherein said insulating material is selected from a group consisting of expanded polystyrene, extruded polystyrene and isocyanurate. 
     
     
         4 . The geo-synthetic composite insulation panel according to  claim 1 , wherein said geo-textile is made of polyester. 
     
     
         5 . The geo-synthetic composite insulation panel according to  claim 1 , wherein said geo-textile is made of a material adapted to absorb adhesive material. 
     
     
         6 . The geo-synthetic composite insulation panel according to  claim 1 , wherein said geo-textile is made of at least one of a glass-type fabric or a geo-textile composite material. 
     
     
         7 . The geo-synthetic composite insulation panel according to  claim 4 , wherein said geo-textile has a variable density. 
     
     
         8 . The geo-synthetic composite insulation panel according to  claim 5 , wherein said geo-textile has a variable density. 
     
     
         9 . The geo-synthetic composite insulation panel according to  claim 6 , wherein said geo-textile has a variable density. 
     
     
         10 . A method for installing a geo-synthetic composite insulation panel for roofing applications, comprising:
 providing a geo-synthetic composite insulation panel for roofing comprising:
 a bottom layer comprising an insulating material, and 
 a top layer comprising a geo-textile laminated on top of the bottom layer; and 
   joining a waterproof membrane to the insulation panel with an adhesive.   
     
     
         11 . The method for using a geo-synthetic composite insulation panel of  claim 10 , wherein the lamination of said top layer on said bottom layer of said insulation panel is completed in a factory setting prior to installation on a roof.
