Seamless Fiberglass Construction

Fiberglass Composite Panels For Ultimate Protection | The fiberglass composite panels block heat from penetrating the truck body because they do not conduct heat. The smooth one-piece wall, roof, and end panels are ideal for cleaning, decal application, and showcasing company graphics. Even more, they absorb energy from impact better than aluminum and there are no seams or rivets for heat or moisture to pass through...

Outstanding Thermal Capacity

Achieve Operational Savings With Superior Thermal Performance | Johnson's exclusive composite construction methods achieve the best R-Value in the industry. The thermal efficiency of an insulated truck body directly relates to the construction techniques and materials used...

High Pressure Foam Insulation System

Excellent Insulation Value And Panel Strength | The insulation value (R-value), of Johnson's foam insulation is R-7.5 per inch of thickness. The high-pressure foam insulation system and improved foam chemistry produces extremely durable, void-free panels, which contribute to reliability and significant operational savings to maintain required temperatures...


TripleSeal Door Gasket

Seal Out Potential For Heat and Moisture Compromise | Heat and moisture intrusion are common issues that result with standard door gaskets. The TripleSeal™ gasket is extremely effective in solving a special low-pressure door-opening condition created when there is a warm, humid ambient outdoor atmosphere, and a driving rain combined with a dry/very cold or frozen environment inside the truck body...

Exclusive ArcticTherm®

Heavy-Duty Liner Meets Food Safety Requirements | Johnson's patented seamless fiberglass ArcticTherm® interior liner is exceptionally strong (2,200-psi puncture resistance) and features a smooth, seamless, easy to clean interior surface. The liner components are designed for repeated food contact use and meets Food Safety requirements when proper cleaning and sanitation protocols are followed. Available in select models.

Fully Encapsulated Cross Sills

Ultimate Under Body Protection | Johnson truck bodies and specialty trailers are designed with a sealed protective sub-floor finish that protects the cross members and insulation from moisture intrusion, impact, and corrosion ...


Automatic Defrost

Address Run-Off Concerns And Reduce Maintenance Costs | Johnson's exclusive automatic defrost system for all-electric cold plate blower refrigeration systems greatly reduces the amount of water and labor needed for defrost operation...

Thermal Break Design

Exclusive Non-Heat Conducting Thermal Break Design | Johnson places a strong pultruded polyester, non-heat conducting thermal break between the steel frame and the interior wall and roof panels to create a non-conductive barrier between structural components and interior panels....

Alpine Optional Interior Linings

The ONLY Liner That Helps Maintain Thermal Efficiency | Great Dane's patented reefer interior liner contains a revolutionary composite layer that seals the trailer's insulation and significantly reduces "out gassing" effects that cause foam insulation to degrade over time....
