Breaking Down Walk-ins
Panels are the building blocks of walk-in coolers and freezers. The two most common types are foamed-
in-place polyurethane and extruded polystyrene. The choice of panel depends on the durability and
insulation efficiency you require. Foamed-in-place polyurethane typically has a higher R-value making
it very efficient for walk-in panels, while the Extruded Polystyrene is more resistant to water penetration
compared to other forms of polystyrene.
Panels
Standard walk-in doors are 34 x 78” but they can be ordered in larger sizes to accommodate skids or
wider carts as needed. Doors can be ordered as a sliding door if space in the walkway is limited. Keep
in mind that non-standard door sizes will be charged as an upgrade to any standard walk-in size.

walk-in
coolers
and
freezers must be durable and easy to
clean. Depending on your space, you
may or may not need a floor of panel
material. Walk-in Coolers that are in a
room with a basement or floor below
require an insulated floor while those
Walk-in Coolers that are on the main
floor with a concrete slab on grade
floor do not require an insulated floor.
Walk-in Freezers will always require an
insulated floor regardless of location in
your building. Common materials for
flooring include aluminum, stainless
steel, and galvanized steel and often in
checkerplate for added traction. The
key to selecting flooring is the weight
capacity. If rolling carts or pallet
jacks will be used, it’s important to get
floors with the proper reinforcement to
support the weight.
