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, 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 increased structural strength.

All panels have tongue and groove construction and gasket is applied to all joints forming an air-tight seal.

Panel Fasteners

All panels are joined together using a camlocking fastener, operated with a hex wrench.

Access holes are sealed with vinyl snap-in caps.

Floorless Models

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 Panels

Floor panels are built with metal bonded to exterior grade underlayment and foamed in place.
Capable of maintaining a load maximum of 1000lbs./sq/ft. when uniformly distributed, and are NSF approved.
