Johnson Refrigerated Truck Bodies   Competitive Aluminum or Steel Bodies
Lowest Life Cycle Cost in the Industry    

The Johnson name has been synonymous with “quality” for 70+ years. Our product is built to last. It will give you the best R.O.I. on your investment & lowest Total Cost of Ownership.

  Aluminum refrigerated bodies have a limited 5 to 7 year life.
Exterior Construction    
Molded fiberglass. Seamless, ultra smooth. No rivets or screws. Impervious to moisture. which can damage insulation. Colors are impregnated permanently. No paint chipping or peeling.   Standard aluminum or steel body Designs are not seamless. Hundreds of fasteners (usually Rivets), are used to assemble the metal panels causing seams and holes where moisture can enter.
Longer life cycle as fiberglass will not rust. Ideal for areas with high road or seaside salt.   Shorter life cycle due to rust and corrosion.
Fiberglass has a high puncture and tear resistance. However, if damaged, can be repaired like new at relatively low cost.   Dents, punctures and tears are typical, along with missing rivets. Can be difficult and costly to repair to like new condition.
Aerodynamic molded seamless roofs, corners and vertical posts provide a smooth surface to reduce wind resistance and improve fuel efficiency.   Most use flat aluminum roof construction with square aluminum top which increases drag. Most also use square aluminum front corners which increases wind drag.
Interior Construction    
A bright, seamless, sanitary white ArcticTherm® fiberglass interior is waterproof, easy to clean. No rivets or screws to snag product packaging or clothing. Highest puncture resistance in the industry.   Aluminum, galvanized, steel or glassboard interior walls and trim angles that require screws, rivets or glue are rough, difficult to clean and present hot spots for food borne contaminants.
Encapsulated cross sills are fully foamed and protected from corrosion. This lowers the operating bed height 3 to 4-in. and improves driver efficiency.   Competitors build 3-4" false wood floors over the top of their cross sills.
Insulation    
Urethane, foamed-in-place under heat and pressure, provides 2.1-lb. density for unequaled temperature retention. Rated at a “k” factor of .14 (BTU/hr./ft2/F/inch thickness of material).   Poured or sprayed foam is typically applied without pressure. As a result, the foam does not have uniform density or flow, leaving un-insulated voids in the walls and roof.
Exterior and interior panels are 0.125-in. thick, which is 182 times more resistant than a steel wall, and 896 times more resistant to heat penetration than an aluminum skin.   To match a 0.125-in. thick Johnson panel requires 112-in. of aluminum, or 22.75-in. of steel.
Doors & Frames    
The fiberglass reinforced panels are not only very strong, but also light in weight. Foam filled under pressure, they provide minimum heat conduction. Powder coated hardware with adjustable cam locks allows adjustment on the gasket seals. Stainless cam locks and hinges also available.   Metal frames are screwed and riveted. Typically they are heavier. Will allow moisture and heat migration. Are also subject to corrosion.
Lights & Wiring    
Exclusive recessed exterior lighting results in less breakage, wind resistance and improved visibility. All wiring is color coded in plastic conduit for ease of accessibility.   High maintenance. Lights are exposed to damage and wind drag. Wiring is exposed or buried in the walls. Difficult to maintain and repair.
Truck Body Blue Book Residual Value

  Aluminum bodies are subject to corrosion and warping. They also depreciate quicker and have lower residual values.
