Great Dane's many unique product offerings for refrigerated trailers include PunctureGuard and ThermoGuard linings. These advanced solutions are superior to other high performance options currently available in the key areas of stiffness and foam adhesion, two critical elements in a reefer's long term durability and thermal integrity.
While strength and light weight are key attributes in any reefer lining material, PunctureGuard and ThermoGuard also address the need for stiffness to help protect the foam insulation in a trailer's walls. This characteristic is very important because the forces from pallets, cargo, or forklifts during loading and unloading operations can be transmitted to and damaging to the foam insulation in the trailer walls, causing it to lose thermal integrity.
The inherent stiffness of PunctureGuard and ThermoGuard comes from the high glass content and its placement in the glass-reinforced, thermoplastic liners. With 70 percent glass by weight, more than any other product on the market, and a design that places the oriented long glass fibers close to, but not too near the surface, these unique liners offer significant stiffness. In addition, the thermoplastic liners remain pliant over time, so impacts from loading equipment will not cause the material to curl away from walls.
Adhesion characteristics are equally important and are addressed in the design of Great Dane's PunctureGuard and ThermoGuard reefer linings. The proprietary and unique adhesion system consists of a specialized layer that serves as a highly effective anchor into the foam insulation. This very strong mechanical bond helps resist delamination caused by gouging, rubbing or denting that can damage the foam immediately behind the liner and cause the liner to separate from the insulation inside the trailer's walls.
At .070 inches, PunctureGuard is incredibly thin and considerably lighter than plywood and conventional FRP linings. In distinct and comprehensive tests measuring strength and impact resistance, PunctureGuard was found to be one fourth to one third stronger than competitive products. Other tests revealed it has up to 50 percent more impact resistance. PunctureGuard is also easy to repair, lowering maintenance costs, and it's easy to clean, making it simpler to maintain the appearance of the liner's smooth, glossy finish.
ThermoGuard, also thin and lightweight, helps maintain the thermal efficiency of Great Dane reefers. Containing a revolutionary composite layer that seals the trailer's insulation, ThermoGuard significantly reduces "out gassing" effects that cause foam insulation to degrade over time. The improvement in thermal integrity helps maintain excess cooling capacity, reducing cooling unit run-time by significntly over five years, as well as lowering resulting maintenance and fuel expenses.
PunctureGuard and ThermoGuard, two exclusive refrigerated trailer linings from Great Dane stand above alternative and competitive solutions in terms of strength, stiffness, adhesion and light weight. The result of Great Dane's continued commitment to research and development of products and unique and innovative manufacturing processes, these high performance linings are helping customers eliminate damage and enhance cargo protection while also increasing productivity, extending the useful life of trailers, and improving resale value.
