Panel Fabrication
Better panel fabrication means one thing: better walk-ins. The panels consist of urethane insulation, which is sandwiched between interior and exterior metal “skin”. This metal skin has been die-formed and gauged for uniformity in size. The edges of the panels are tongue and groove with Tafco SureLock fasteners, which are “foamed-in-place” at time of fabrication.
The panels are provided with NSF listed PVC gaskets, which are “foamed-in-place” on both interior and exterior sides of the panel. The gaskets are impervious to all stains, greases, oils, mildews, etc. They ensure an air-tight seal and also eliminate the need for seam calking.
The urethane foam is bonded to the inner surfaces of metal pans, having an average thermal conductivity (K-Factor) of 0.13 BTU/hr/ft²/degrees/Fahrenheit/inch. Also, the panels have an overall coefficient of heat transfer (U-Factor) of no more than 0.0312. As tested in accordance with ASTM C 518-2004, the R-Factor for coolers at temperatures of 55 °F is greater than 29.0 for 4” thick panels. The R-Factor for 5” thick panels is greater than 36.0. For freezers at temperatures of 20 °F, the R-Factor is greater than 32.0 for 4” thick and greater than 40.0 for 5” thick panels.

The prefabricated urethane foamed panels shall be supplied with a Class 1 fire hazard classification according to UL 723 (ASTM-E-84), as tested by Underwriters Laboratories, Inc. Panels shall have a flame spread rating of 25 or less and bear a certified Underwriters Laboratories, Inc. label.
Tafco prides itself in using CFC free foam. This environmentally friendly foam is 100% CFC and HCFC free, with a 0% ODP (ozone depletion potential).
Panels are offered with a wide variety of metal and other finishes. These include Galvalume, Stainless Steel, Aluminum, Galvanized Steel, Embossed, White, San Tan, FRP, antimicrobial coated metal, and multiple color finishes.
