Abstract
A composite roof structure, and a corresponding method of fabricating the structure, are disclosed which includes use of a layer of adhesive material (preferably a foamed, cellular adhesive such as polyurethane) along with a flexible membrane including a rubber-like sheet having a fleece-like matting secured to the underside thereof. The adhesive is preferably sprayed onto a roof substrate and prior to complete solidification thereof the membrane is pressed into the adhesive so that the matting becomes embedded therein.
Claims26
A composite roof structure adapted to be supported by a roof substrate and comprising:
- a layer of cellular synthetic resin adhesive material adapted to be secured to said substrate;
- and
- a flexible membrane including a sheet of flexible material having fleece-like matting secured to the underside thereof,
- said membrane being attached to said adhesive material with at least a portion of said matting being imbedded within the adhesive material.
A method of forming a composite roof upon a substrate, comprising the steps of:
- providing an initially flowable adhesive material which upon solidification thereof presents a cellular matrix;
- applying said initially flowable adhesive material onto said substrate;
- and
- prior to complete solidification of said adhesive material, applying a flexible membrane thereto and allowing the adhesive material to solidify,
- said flexible membrane including a flexible sheet having a fleece-like matting secured to the underside thereof,
- said membrane-applying step including the steps of placing said matting in contact with said adhesive material prior to complete solidification thereof, causing said matting to become at least partially embedded within the adhesive material, and thereafter allowing the adhesive material to solidify.
