Insulation must be protected from open flame and kept dry at all times. Install only as much insulation as can be covered the same day by completed roof covering material. Hunter Panels will not be responsible for specific building and roof design by others, for deficiencies in construction or workmanship, for dangerous conditions on the job site or for improper storage and handling. Technical specifications shown in this literature are intended to be used as general guidelines only and are subject to change without notice.

Our Warranties are Second to None

DMI total system warranties protect all aspects of your metal envelope system, whether that be the watertightness of the roof or siding, the Galvalume ® steel, or the durable PVDF KYNAR® finish. When looking at warranties for your system, it is important to note that not all warranties are created equal. DMI warranties ensure the watertightness of all flashing conditions, trims, curbs, valleys, and penetrations. Building owners are protected with a total system warranty - “from the deck up” when using DMI insulation, fasteners, and underlayment. Our warranties are backed-up by a full-service Engineering Department, generating project specific shop drawings. Quality control is monitored by a minimum of two on-site inspections by our Field Technical Inspectors. DMI Total System Warranties give building owners and design professionals confidence that they are receiving the highest quality and most complete warranty available in the industry.
