Dicor's Tufflex PVC roofing membrane is flexible, stretchable, puncture Defiant, and recyclable. The flexibility of this roof material easily helps it conform to multiple contours of an RV roof, making installation efficient and hassle free. Products' water based PVC adhesive strongly resolves Tufflex to wood decking making for one 'tuff' roof. High solar reflectivity and thermal emissivity help keep the coach cooler in the summer.
