Insulation

Standard insulation is foamed-in-place Non-CFC U.L. Class 1 rated urethane foam. It has a thermal conductivity (K Factor) of not more than .125* BTU/Hr/Sq. ft/Degrees/F/in. and overall heat transfer coefficient (U Factor) of not more than .030 BTU/Hr.Sq.Ft. Class 1 urethane foam has a flame spread of 25 or less overall. Recommended wall thickness is nominal 3.5″ for storage temperatures down to +5°F and nominal 5.25″ for temperatures +5°F or lower and all outdoor freezers. Nominal 4″ panel is also available.

*Based on normal operating temperatures.

Panel Construction

Walk-ins are all custom designed to fit the individual customers’ needs. Each panel consists of an interior and exterior metal pan with structural wood frame or high density foam rail frame. These pans are separated by rigid foam-in-place self-extinguishing urethane insulation which adheres to the interior of the pans providing inoreased structural strength. All panels have tongue and groove construction.

Panel Fasteners

All panels are joined together using a cam locking fastener, operated with a hex wrench. Access holes are sealed with vinyl snap-in caps. Ceilings are typically attached to walls using lag bolts. When height restrictions dictate, or it customer specifies, walls can also camlock to ceilings.

Floorless Models

Alignment screed is furnished for all floorless models. Screeds are designed to be anchored to masonry floors to provide an accurate template for the erection of wall panels.

Floor Panel

Floors are built with metal bonded to exterior grade underlayment and foamed-inplace. Floors are capable of maintaining a load maximum of 1000 lbs./sq/ft. when uniformly distributed, and are NSF certified.
