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.

Description

FIELD OF THE INVENTIONThe present invention relates to roofing insulation. More particularly, it relates to a geo-synthetic composite insulation panel and a method of using such a panel in roofing applications.BACKGROUND OF THE INVENTIONSeveral types of panels are used for providing insulation in roofing. Typically, prior art panels are made of expanded polystyrene or EPS. Several types of densities of polystyrene are used including type 1, type 2 or other different densities.Typically such panels are used to insulate roofs and generally receive a waterproof membrane. In these cases, construction panels, either made of wood fiber, perlite, recycled asphalt or gypsum or other materials are placed over the insulation. It can be noted that these products are the weakest link in the whole roofing assembly when wind uplift pressure is applied.Therefore, there is still presently a need for a composite panel that better distributes stresses imposed on the insulation, improves its resistanc...

AI Technical Summary

Benefits of technology

The present invention provides a geo-synthetic composite insulation material for roofing that addresses various needs. The material comprises a bottom layer of insulating material and a top layer of geo-textile laminated on top of the bottom layer. The geo-textile allows absorption of adhesive material used to fix the waterproof membranes on the insulating panel, and reinforces the surface of the insulating material through stabilization and redistribution of loads, making the roofing system more resistant to punctures and other compressive forces. The geo-textile material enhances the whole integrity of the roofing system. The method for installing the geo-synthetic composite insulation panel for roofing applications involves joining a waterproof membrane to the insulation panel with an adhesive.
