Johnson’s Void-Free 2.1-lb. Foamed-In-Place Insulation Sandwich |
| The “Sandwich Construction” consists of … |
| • Exterior molded fiberglass panel |
| • Interior ArcticTherm liner |
| • Steel tubes and “U-shaped hats” mounted against the interior panel |
| • Pultruded polyester fiber reinforced transparent, non-heat conducting thermal breaks |
| • Void-free, 2.1-lb. foamed-in-place polyurethane insulation foamed under heat and pressure in a state-of-the-art platen press. |
The sandwich panel is chemically and mechanically bonded for outstanding structure strength and has an outstanding insulation value. The end result is the ability to hold to precise product temperature control during the hottest of days. This is most important to meeting Food Safety product protection guidelines.
Examples of Heat Transfer of side and rear walls between a Johnson fiberglass body and a traditional sheet and post aluminum body is shown by these thermal imaging photos. To demonstrate the amount of heat transfer, the interior temperature was 120°F for both bodies in the study with an ambient exterior temperature of 40°F. |
