FOAM PANEL STORAGE
If foam walk-in panels require storage at the job site prior to installation, the following steps must be taken to
protect the panels against both staining from moisture and sunlight, and denting by workers and traffic.
Whenever possible, the panels should be stored indoors, and should remain in the crating pallet they were
originally shipped in. If the panels were uncrated as they were unloaded from the delivery truck, and they are being
stored indoors, they should be stored vertically on skids with spacers between the panels.
When storing panels in a vertical position, always place the female rail (grooved) edge down (see illustration
below.) This method of storing panels will provide proper ventilation, permit drain-off of condensation moisture
and protect panels against the formation of white rust stains.
If the panels must be stored outdoors, follow the same procedure as indicated for indoor storage WITH THIS
ADDITION: Cover the panels completely with an opaque polyethylene water-proof material to protect against rain,
snow, heat and sunlight.
The illustration below shows the method for storage outdoors when panels are not left in palletized crates.
Note: Nor-Lake always recommends equipment to be installed once received but understands storage may be
required. Nor-Lake does not guarantee issues related to storage, such as handling damage, storage damage,
panel aging, etc. We would recommend the locks be oiled and the panels be wiped down with a white oil.

CONSTRUCTION DIAGRAM
The construction diagram, as furnished with each walk-
in, is a detailed plan that illustrates the placement of
every wall, corner, ceiling and floor panel that comprises
a complete, individual walk-in.
The construction diagram for all installations clearly
shows the direction of the male and female formed
profile of every wall panel and every corner panel.
All sections used to construct your walk-in are marked with
a specific part number on the section, corresponding with its
location on the construction diagram.
If the walk-in is floorless, then a diagram showing the vinyl
screed (floor sealer) arrangement is provided.
The vinyl screed combines the capability of retaining the wall
panels in place while providing the inner and outer cove at the
junction of the walls and the building floor (a requirement of
Standard No. 7 of the National Sanitation Foundation (NSF).
IMPORTANT! Do not attempt to erect a floorless walk-in
FREEZER on an existing building floor that has not been
specially prepared and adequately insulated for below
freezing storage temperatures!

SECTION LATCHES
All wall, corner, ceiling and floor panels are joined and locked together by the
mechanical action of section latches which are integrally foamed into the panels
near the perimeter edges. A section latch consists of two halves – a lock housing
which contains a cam actuated locking arm, or hook, and a strike housing which
contains the engagement pin. Both housing halves are securely anchored in the
foam core of the panel. The lock housing is always located in the male-formed
edge and the strike housing will be found in the female-formed edge of the panel.
TO OPERATE LATCHES
Walk-InInsTallaTIon
1. Insert the hex wrench
(packed in the hardware
bag) through the access
hole in the interior
panel metal into the hex
opening of the section
latch. Turn wrench in
a counterclockwise
direction to ensure
that the lock is fully
unlatched

2. Push the sections
tightly together and turn
the wrench 1/4 turn in a
clockwise direction. This
will engage the locking
arm (hook) over the pin in
the strike housing.
3. Continue turning the
wrench to a full stop
(approximately 3/4 of a
complete turn from the
unlatched position) to
complete the locking
operation.
Fully Extended Cam Lock
Latches on some panels
will have to be turned
counterclockwise to
activate the locking cam.
These latches will be

SITE SELECTION, BASE PREPARATION AND LEVELING THE FLOOR
WALK-IN COOLER OR FREEZER WITH A FLOOR
One of the most important considerations in the construction of a walk-in cooler or freezer is the building floor or the
surface upon which the walk-in will rest. As with any structure, a firm and level foundation is essential to achieve
a perfect end result. If the surface is not perfectly level and smooth, appropriate steps must be taken to provide
the proper base. The positive action of self-closing doors, proper door gasket seal and condensate removal all
depend directly upon the level and plumb installation of all panels.
If the walk-in is to
be installed next to
an existing building
wall(s), make sure
that a MINIMUM OF 2"
REMAINS BETWEEN
THE WALK-IN AND
THE BUILDING
WALL(S) to allow for
irregularities of the
building wall(s) and to
permit a free flow of
air between the two surfaces.
NOTE: Indoor walk-in(s) must be in an environmentally controlled
space. Relative humidity should be kept between 30% - 60%,
maintaining a dew point of 50°F or less.
In some cases, the surface upon which the walk-in is to be
installed was especially prepared for installation and it is perfectly
level and smooth. The walk-in floor, in this case, may be installed
without further preparation. Before beginning, however, an
appropriate vapor barrier should be placed over the surface
that the walk-in will occupy. Asphalt felt paper (50#) or a 6 mil
polyethylene film, are suggested materials. These are provided
by the installing contractor.

FLOOR INSTALLATION (Shim Leveling Method)
FOR WALK-INS SUBJECT TO LIGHT TO MODERATE LOADS
Locate the highest point within the perimeter lines. A transit or
surveyor’s level or rotary laser level is an ideal instrument to use for
locating this point. When the highest point is located, mark it directly
on the floor and refer to the construction diagram to determine where
the high point is located with respect to the walk-in floor plan.
One of the most important procedures that will be encountered in
the construction of a walk-in with a floor is LEVELING THE FLOOR.
It must be PERFECTLY LEVEL! If it is not, the wall panel will
follow the irregularities of the walk-in floor which will directly affect
subsequent procedures such as latching, panel gasket seal, ceiling
panel assembly among others.
Using the construction diagram as a guide, select the floor panel that will be located directly over the highest point
and place it in that position while observing the drawn outline on the building floor.
After the first floor
panel is positioned,
it must be properly
leveled. To achieve
this, shimming material
of varying thicknesses
must be used. Cedar
building shingles are
ideally suited for this
procedure.
IMPORTANT! EVERY
FLOOR PANEL MUST
BE SUPPORTED ON
ALL FOUR SIDES
AND THE ENTIRE
UNDERSIDE, AT
LEAST EVERY 12"
BY EITHER THE
BUILDING FLOOR
OR BY SHIMMING.
HOWEVER, OTHER
MATERIALS THAT
ARE RESISTANT TO ROTTING OR COMPRESSION ARE ALSO ACCEPTABLE.
After the first floor panel has been leveled perfectly, trim away the excess shim material so that none projects from
the panel at any of the four edges.
From the construction diagram, determine which floor panel will be installed next and where it will be situated on
the floor plan. Prepare shimming material for the second panel at each point where shimming material was used
beneath the first floor panel. The shimming material thickness must be such that it will support the second floor
panel at exactly the same height as the first panel along the entire length of the joint. NOTE: In many cases, the
shimming material will be the same thickness as the adjacent shimming under the first panel.

9/18 Rev. K 132617 ©2018 Nor-Lake, Inc. A division of Standex International Corp. All rights reserved.
Place the second panel in position next to the first floor panel but
DO NOT LOCK!
Shim the second panel, where necessary, using the same procedure
as was used on the first panel. When all four edges of the second
floor panel are properly shimmed, lock the two panels securely
together. Using the same technique for leveling, check the levelness
of the two sections in all directions by placing the level across the
joint at several points and, again, check the levelness of the floor
panels in the direction of the panel joint.
Refer to the construction diagram and install the remainder of the
floor panels using the same procedure as was used for the first and
second floor panels. When all of the floor panels are installed and
leveled perfectly, check the section latches for full and complete
locking.
Trim excess vapor barrier.

SITE SELECTION, BASE PREPARATION
WALK-IN COOLER WITHOUT A FLOOR INSTALLED ON 1” VINYL SCREED
IMPORTANT! Do not attempt to construct a floorless walk-in FREEZER on a existing building floor that has not
been specially prepared and adequately insulated for below freezing storage temperatures. Note: All thermal
breaks in floor slab must be exposed, including the partition wall.
To install a vinyl screed assembly on an existing floor, proceed as follows:
Locate the screed (floor sealer) diagram which was packed in the hardware box and, using it as a guide, draw
an outline of the outside dimensions of the installed screed directly onto the building floor where the walk-in will
be situated. These dimensions will be 1 1/2” larger than the overall dimensions of the walk-in in both directions.
If the walk-in is to be installed next to an existing building wall(s), make sure that a
MINIMUM OF 2” REMAINS BETWEEN THE DRAWN OUTLINE AND THE BUILDING WALL (s) to allow
for irregularities of the building wall (s) and to permit a free flow of air between the two surfaces.
CAREFULLY CHECK FOR SQUARENESS by insisting that the two dimensions between opposite corners are
equal (Figure 1).
One of the most important procedures that will be encountered in the base preparation is LEVELING THE SCREED.
It must be PERFECTLY LEVEL! If it is not, the wall panels will follow the irregularities of the building floor which
will directly affect subsequent procedures such as panel latching, panel gasket seal, ceiling panel assembly and
others.
After the outline of the screed assembly is completed, locate the highest point within the outline on the floor where
the screed will be installed. Screed sections are 5 1/2” wide. A transit or surveyor’s level is an ideal instrument
for this purpose. Mark the highest point on the floor (Figure 2) and, referring to the screed diagram, identify and
locate the appropriate screed section and position it directly over the highest point.

After the first screed section is positioned, it must be LEVELED PERFECTLY not only over its length but, across
its width, as well. To achieve this, shimming material will most likely be required. Vinyl floor tile is ideally suited for
this purpose. However, other materials that are resistant to rotting or compression are acceptable. IMPORTANT!
EVERY SECTION OF SCREED MUST BE SUPPORTED AT LEAST EVERY 12’’ BY EITHER THE BUILDING
FLOOR OR BY SHIMMING (Figure 3).
Assuming that the first screed section has been perfectly leveled, refer to the screed diagram and select an
adjoining screed section and level it perfectly in both directions, shimming wherever necessary. Continue leveling
the remainder of the screed sections until the entire assembly is in position. Check the assembly to make sure
that the outer edges are located exactly on the drawn outline on the building floor.

When the entire screed assembly is leveled and supported by shimming, as required,
CAREFULLY AND WITHOUT DISTURBING THE SHIMMING MATERIAL, lift the screed sections, tip them
upside-down and apply a heavy bead of construction sealant to the bottom of the screed section along both of the
edges that contact the building floor surface. The diameter of the sealant bead should be larger than the thickest
shimming material to ensure a complete, air-tight seal along the entire length of the screed (Figure 4). NSF
approved sealant is provided and will be found in the hardware box.
Immediately after applying the construction sealant to a screed section, replace the screed section to its original
location on the building floor WITHOUT DISTURBING THE SHIMMING MATERIAL and place a sealer splice every
joint in the screed assembly (Figure 4). Since the sealer splice is intended to keep adjacent screed sections in
alignment, approximately one-half of the sealer splice should lap each section. It need not be fastened in place
(Figure 4). NOTE: Seal all screed joints with sealant. Make a final check for squareness, levelness and
whether the screed assembly is located properly with respect to the drawn outline on the building floor.
Follow by securing the screed assembly to the building floor with fasteners that are appropriate for the building
floor. These fasteners are not provided and must be obtained by others.
Fasteners should be applied down the center line of the inside of the screed at intervals of approximately 36’’;
however, where shimming is used, apply the fasteners through the shimming material, NOT BETWEEN the
shimming. When the entire assembly is secured in position, trim away all excess construction sealant and
shimming on both edges of the screed. Trim flush with the sealant lip of the screed and touch up any areas where
the construction sealant is not making a perfect seal (Figure 4).
NOTE: In the event that the building floor was specially prepared for the installation and no low or high points are
detectable, it is possible that no shimming will be necessary. It will then only be necessary to apply construction
sealant to the bottom of the screed and secure the screed directly to the building floor. The entire procedure, as
described, must be followed explicitly, however, except for the details that pertain to the shimming.

ALTERNATE SHIMMING METHOD FOR 1’’ VINYL SCREED
If the surface that the vinyl screed will occupy is level, except for an occasional low point, the screed may be
secured directly to the building floor and compensation for the low points may be achieved by shimming the
support shoulders on the inside of the screed.
When employing this method, the low points should be marked on the building floor in the vicinity of the drawn
outline for reference. After the screed has been sealed and secured, leveling may proceed with special attention
being focused in the areas marked as being low points.
Vinyl floor tile is often chosen as shimming material and strips (5/8’’ wide maximum) are cut and placed on top
the supporting shoulders of the screed to provide a level surface for the wall sections to rest upon. Strips of tape
should be applied to hold the shimming material in place (Figure 5).
IMPORTANT! Shimming the support shoulders on the inside of the screed is ideally suited for minor irregularities
on the building floor and has the advantage of complete screed-to-floor contact over the entire perimeter of the
assembly. IT IS NOT RECOMMENDED, HOWEVER, FOR EXTREMELY IRREGULAR BUILDING FLOORS.
Excessively thick shimming material on the support shoulders may elevate the wall panels to a point where the
effectiveness of the uppermost screed sealing flanges would be compromised. Shimming thickness of more than
3/4’’ should be avoided! If shimming the support shoulders of the screed is selected, the entire procedure, as
described, must be followed explicitly to ensure squareness and levelness over the entire screed assembly.

SITE SELECTION, BASE PREPARATION
WALK-IN COOLER OR FREEZER WITHOUT A FLOOR INSTALLED ON FOAMED SEALERS
IMPORTANT! Do not attempt to erect a floorless walk-in FREEZER on an existing building floor that has not been
specially prepared and adequately insulated for below freezing storage temperatures. Note: All thermal breaks
in floor slab must be exposed, including the partition wall. To install a foamed sealer (screed) assembly on
an existing floor, or on a properly prepared floor for freezers, proceed as follows:
Locate the floor sealer (screed) diagram that was packed in the hardware box and, using it as a guide, draw an outline
dimensions of the installed sealer (screed) assembly directly onto the building floor precisely where the walk-in will
be situated. These lines will be exactly the same dimensions as the dimensions of the walk-in in both directions.
If the walk-in is to be installed next to an existing building wall(s), make sure that a MINIMUM OF 2” REMAINS
BETWEEN THE DRAWN OUTLINE AND THE BUILDING WALL(S). This space will allow for irregularities in the
building wall(s) and will permit a free flow air between the two surfaces. CAREFULLY CHECK FOR SQUARENESS
by insisting that the dimensions between opposite corners are equal (Figure 1).
Since the foamed sealer (screed) is retained in position by a 3/8” thick plywood sealer guide, which will be secured
to the building floor, it is imperative that the sealer guide be accurately located, as well, on the building floor. Refer
to the sealer guide diagram which was also packed in the hardware box. On the diagram, you will notice that
the sealer guide is located 78” INSIDE the drawn outline which represents the outside dimensions of the sealer
(screed) assembly. Further, Fig. 1 illustrates that the sealer guide is 2 1/4” wide centered beneath a 4” wide sealer
leaving a border of 7/8” along each edge. Draw another outline of the outside dimensions of the sealer guide
directly onto the floor. There should be exactly 7/8” between the new sealer guide outline and the previously drawn
sealer (screed) outline (Figure 2, on next page).

One of the most important procedures that will be encountered in the base preparation is LEVELING THE
SEALER (SCREED). It must be PERFECTLY LEVEL! If it is not, the wall panels will follow the irregularities of the
building floor which will directly affect subsequent procedures such as panel latching, panel gasket seal, ceiling
panel assembly and other.
After the outline of the sealer (screed) and the sealer guide is completed, as shown in Figure 2, locate the highest
point within the outline on the floor where the screed (sealer) will be installed. (Sealer sections are 4” wide). A
transit or surveryor’s level is an ideal instrument for this purpose. Mark the highest point on the floor as illustrated
on Figure 3.

SEALER GUIDE INSTALLATION
Locate the SEALER GUIDES. They are bundled together and packed along with the walk-in corner or wall panels
and are labeled accordingly. Sealer guides are strips of 3/8” plywood 2 1/4” wide as shown in Figure 1.
Refer to the SEALER GUIDE DIAGRAM. Select the proper sealer guides and position them as shown by the
circled letters on the diagram. Each length of sealer guide is marked with a circled letter that corresponds to the
circled letters on the sealer guide diagram.
Each sealer guide, when positioned properly, will have its outer edge precisely over the INSIDE OUTLINE drawn
on the building floor, Figure 2, and its outer edge will be exactly 7/8” from the outline which represents the foamed
sealer outer edge. The quality of workmanship performed in locating and securing the sealer guides will be
transmitted directly to the location of the foamed sealers (screeds) and, subsequently, to the overall construction
of the complete walk-in. BE EXACT! Refer to Figure 1 and Figure 2.
When all sealer guides are in position, make a final CHECK FOR SQUARENESS and secure them to the building
floor with fasteners that are appropriate for the surface. NOTE: This can either be a mechanical fastener or
construction grade adhesive. If the sealer guide is positioned over a polystyrene or polyurethane thermal breaker,
a compatible construction adhesive may be used.
FOAMED SEALER (Screed) INSTALLATION
Refer to the FOAMED SEALER DIAGRAM. Identify and locate the sealer section that will be positioned directly
over the highest point which was determined earlier and marked on the building floor (Figure 3).
NOTE: All foamed sealers are male-formed on one end and female formed on the opposite end. The configuration
of the ends is clearly indicated on the diagram. Also, make certain that the strike housing portion of the section
latches is visible on the upper edge of the sealer when it is in position (see Figure 1 and Figure 2).
