A few weeks ago, we wrote a blog answering some of the top questions we receive before the installation of KPS Global panels. For part two of our series, we dive deeper and answer some of the more complex questions, going over some of the specifics that may happen during the installation process.
1) What is the correct order to install floor panels in a walk-in?
If gaps between insulated floor panels exceed 1/4", put foam under the insulated panels where the gaps are and trim any excess foam before applying sealant. It’s important to note that shims may be needed under the floor.
2) What should I do if the gaps between insulated floor panels are more than 1/4″?
For proper floor panel installation, the floor panels should be laid out in the correct sequence according to the assembly drawings and blueprints. Start locking end cam locks, ensuring flush and square edges, then move to the middle.
3) How can I correctly install the wall panels of a walk-in?
When installing walk-in cooler or freezer panels, it is important to follow the correct sequence according to the assembly drawings and blueprints. Generally, start with a back corner and work around the unit, installing the wall panels in sequence, ensuring flush edges and tight joints. Always start the installation with a corner panel, preferably the corner in the tightest location. Make sure the cam-lock holes are to the right as you stand walls up. When connecting/locking to another wall panel, start at the top of the panel to make sure the height is the same.
4) If the walk-in panels aren’t tight at the joint, what should I do?
If the walk-in panels are not tight at the joint, the cam locks need to be completely reset and the insulated panels need to be adjusted and relocked. You should also check for foam in the locks. If the cam locks are still not tight, contact KPS Global. To learn how to reset the cam-lock, you can watch this video.
5) What are the steps to install the ceiling panels on a walk-in?
For proper panel installation, the ceiling panels of a walk-in should be installed in the correct sequence according to the assembly drawings/blueprints/specifications, locked together, and lag-bolted or cam-locked to the wall panels.
If only the front side is exposed, start with the front and work your way back to ensure that the exposed edge is flush. It is also recommended to build the walls of a walk-in in a U-shape to help keep the box square and from falling over. This means leaving one wall side open while the ceiling panels are being installed.
6) I can’t find the Thermal break or vapor barrier in a walk-in freezer installation, what should I do?
If the thermal break strip is not visible in a walk-in freezer installation, immediately notify the GC along with pictures of the issue. The vapor barrier is installed under the concrete and sometimes isn't exposed. It is recommended to contact the general contractor before proceeding in either instance.
7) How do I correctly install the plug buttons on a cam-lock insulated panel?
Plug buttons are an aesthetic piece that covers the hole where the cam-lock is activated and should be easy to insert with a rubber mallet or the end of a hammer. Please take care not to hit the panels directly when using any tools, as this could lead to damage.
8) How should the door sweep on a walk-in door be adjusted?
The door sweep on a walk-in door should be adjusted to ensure proper seal and free movement of the door. The sweep gasket should come installed on the door from the factory. You may need to make adjustments up and down depending on the floor at your site to ensure that the door is sealed. KPS Global walk-in swing doors have adjustment screws to lower and raise the door sweep.
9) What should I do regarding trim and penetrations?
Trim and penetrations should be installed according to the assembly drawing and all penetrations should be sealed completely with spray foam and silicone.
10) How can I correctly install the jamb guard assembly on a walk-in door?
To install the jamb guard assembly on a walk-in door, first remove the plastic thermal break and the jamb metal and replace the interior wood jamb if necessary. In some cases, the jamb guards should be installed on the doors at the factory. If not installed, or if you are unsure on how to proceed, please utilize KPS Global specs or contact your KPS Global representative for assistance.
11) What items constitute the tapered roof system of an outdoor walk-in?
The components of the tapered roof system of an outdoor enclosure are tapered blocks, roofing board (plywood), polyethylene sheet, adhesive strips, and a termination bar.
12) What preparation steps are required for the top panels before roof membrane installation on an outdoor enclosure?
The top panels of the outdoor enclosure should be checked for debris and rough edges, which should be sealed with tape or sealant. Make sure all the top panels are installed and lagged or locked down.
13) Can you explain the installation process of the roof membrane on an outdoor enclosure?
For a flat roof, the first tab should be aligned per the manufacturer’s specifications. Make sure the membrane roof fits the outdoor enclosure, as it may be necessary to snap a line to confirm the roof is installed correctly. From there, continue with the remaining tabs, fold corners and install the termination bar.
14) What is the recommended method to secure the membrane roof to the outdoor enclosure?
The membrane roof should be fastened using manufacturer-specified screws and fastening plates to the outdoor enclosure, spaced according to the manufacturer’s drawings. Please note that a termination bar is needed for the edge of the box.
15) Can you specify how the door sections of a walk-in cooler or freezer should be installed?
Door sections of a walk-in cooler or freezer are to be installed in sequence with the wall panels and per blueprints and KPS Global specs, and they should be set plumb and level. Additionally, make sure to install the door stabilizer. It’s important to test the doors to make sure the sweep isn’t dragging and the walk-in door is closing properly once installed. One way to do this is to make sure the measurement of the top of the door equals the measurement of the bottom of door.
16) What is the correct method of installing the interior ramp in a walk-in with a floor?
After applying sealant to the ramp cavity, follow the KPS Global blueprints and specifications for proper ramp installation.
17) How should the threshold of a walk-in door installation be done?
Once walk-in door has been installed and is functioning correctly, ensure the threshold is flush with the finish floor and is completely sealed around the perimeter.
18) What is the procedure for installing the exterior ramp of a walk-in?
For proper ramp installation, the assembly drawing should be followed for the placement and fasteners of the exterior ramp.
19) In the event that a panel requires unlocking and repositioning during the installation of a walk-in what is the correct procedure?
For a standard panel of a walk-in, the cam wrench should be turned counterclockwise until it stops to reset the cam action. However, on a double tongue panel, you may need to turn the cam wrench clockwise.
20) Can you clarify the right method of operating the cam action fasteners?
Once the walk-in panels are set in place and confirmed to be level, the cam can be locked. To do this, insert the cam key into the lock hole and turn the key towards the female lock. You should see the panel pull tight. Once done, there should be 3/16" in between the locked panels.
