Walk-Ins

Dimensions

We use standard nominal outside dimensions on our walk-ins to meet most requirements. Custom sizes are available to meet building limitations, column obstructions or internal shelving or pallet arrangements.

Room heights are available in 1'0" increments. Overall heights are determined by the type of floor application used.

• Standard 4" Insulated Floor Panels; 6' 6 ¼" through 26'6 ¼" with single span panels (indoor applications). Additional heights are available.
  
  
• Insulated 4" high Vinyl or Metal Foamed Screeds; 6' 6 ¼" through 26'6¼" with single span panels (indoor applications). A thermal break in the building floor is recommended.
  
  
• Vinyl Screed, 1 ½" high; 6'3 ¾" through 26'3 ¾" with single span panels, (indoor applications). A thermal break in the building floor is recommended.
  
  
• Flat Bottom Wall Panels; 6' 2 ¼" through 26'2 ¼" with single span panels (indoor applications). A thermal break in the building floor is recommended.

(All dimensions listed are based on 4" thick insulated panels.)

Construction

Our walk-ins are built using modular panel construction. This allows for future enlargement of the rooms by adding panels as required to change the size and/or layout. Panels are interchangeable with other panels and will lock together tightly.

All panel edges are foamed with a tongue or groove for perfect alignment when assembled. PVC gaskets are foamed-in-place on both the interior and exterior edges to provide an airtight seal. Panels are equipped with "Posi-Loc" cam action locks foamed-in-place to draw the panels together tightly.

Panels are filled with polyurethane foam insulation foamed-in-place to a minimum of 2.2 pounds per cubic foot density. Panel thermal conductivity (K factor) is .133 BTU/hr/sq.ft/degree F/inch. The overall coefficient of heat transfer (U factor) is .033. Insulating efficiency rating (R value) is 30.1. Our polyurethane foams meet the current Montreal Protocol.

All panels are:

• Constructed to meet NSF Standard #7
• Constructed to meet Factory Mutual Standard 4880 for Class 1 Fire Rating
• Tested under UL 723 for surface burning characteristics
• MEA approved for use in New York City
• Approved for use in the State of California
• Approved for use in Los Angeles, California
• Approved for use in the State of Oregon
• Approved for use in the State of Ohio
• Approved for use in Houston, Texas
• Approved for use in Dade County, Florida

Doors

Doors are flush mounted style with full 4 inch insulated thickness and finished to match the adjacent wall panels. A magnetic gasket seals the fiberglass reinforced door perimeter against stainless steel channels attached to a fiberglass reinforced door/jamb. In low temperature rooms, a frame heater wire is provided in the channel to eliminate condensation. A flexible double blade sweep gasket seals the bottom of the door to the door sill.

Each door is hung with heavy-duty cam-lift hinges. A pull handle with cylinder lock and interior safety release is provided. Hardware is attached to heavy aluminum backing plates with stainless machine screws for durability. Door sections include a vapor proof light fixture, light switch with pilot light and a thermometer. Freezer doors include a heater wire and a pressure relief port.

Doors are available in 26", 30", 34", 36", 42", 48", 54" and 60" widths and 68", 72", 78", 84" and 90" heights. Custom door sizes, sliding doors and overhead doors are also available.

Floor and Floorless Rooms

Walk-ins are provided with or without insulated floor panels as the application dictates. Standard floor panels are available with 2" and 4" foam thicknesses. Our panels are designed for loads up to 700 pounds per square foot, evenly distributed. Various finishes are available.

• .100 smooth aluminum
• 16 gauge 304 stainless steel
• 16 gauge galvanized (not NSF approved: for use under tile, concrete or applications not requiring NSF approval)
• .100 diamond tread aluminum for heavy-duty use.
  Note: Floor plate overlay is available.

Floorless rooms are provided with one of the following bases;

• Flat bottom wall panels mount directly to the building floor with mounting angles.
• Vinyl u-channel mounts to the building floor and holds the wall panels in place.
• 1 ½" high coved vinyl screed mounts to the building floor and holds the wall panels in place.
• 4" high vinyl or foamed metal screeds mount to the building floor and the wall panels mount to the screeds.
