Thermal Liner Panels: Restore Solutions for Walk-Ins

Thermal liner panels are a quick and efficient solution for all cold storage industry applications such as walk-in coolers, to improve performance and appearance issues. 

Due to the significant investment walk-ins require for any businesses,  it can be alarming to see visible wear and tear. It is important to note this does not necessarily signal a full replacement is needed. 

The cost to fully replace a temperature-controlled walk-in not only includes the cost of the unit and labor, but also the opportunity costs. The costs incurred include temporarily storing products and conducting the exercise of removing the old unit and the installation of the new.

KPS Global identified the obvious challenges this presents and has since introduced a fast and effective solution to extend the life of existing insulated panels by up to five years.

These panels are a great solution for businesses seeking a quick and effective solution that improves R-Rating, appearance, and performance.  In this blog we will discuss what thermal liner panels are, when to use them, and what the benefits are.

What Are Thermal Liner Panels?

Think of thermal liner panels as insulated wallpaper that can be applied to either the inside or outside of a walk-in cooler and they serve two main purposes:

  1. Enhance Appearance
  2. Improve R-Value 

Installing these panels extends the life of your existing walk-in by restoring it to like new conditions. They are manufactured using metal that is bonded to an insulated core. Once the manufactured panels are complete, they are applied to the existing panels and attached using a proprietary strip assembly system and internal gasket seal.  Below are images that show corroded panels in an existing walk-in and the after once thermal liner panels have been applied.

When To Use

Thermal liner panels provide a great option to extend the life of existing walk-ins and avoid costly business interruptions.  There are two common uses. 

The first application being: visible damage to existing walk-in panels that could result from equipment impact or food and liquid have spilled and created visual defects or worse, corrosion where food inspectors are threatening to shut down operations. 

The second application being: issues in decreased performance of existing walk-ins, for example, your walk-in not holding at the correct temperature.

Other situations where liner panels make sense include:

  • Normal wear and tear
  • Discolored, stained or corrosion of panel surfaces.
  • Impact by carts, lifts, or pallet jacks
  • Addressing food safety issues

It is important to note that thermal liner panels are NOT appropriate for cooler to freezer product conversion.


Installing thermal liner panels as a solution to restore your walk-in to like new conditions is extremely beneficial for a wide range of  reasons. 

First, the time-saving benefits of the quick installation process and not having to shut down the store completely are great advantages to this solution. 

Secondly, thermal liner panel systems improve the performance of the walk in by increasing the R-value by providing an additional layer of insulation. 

Additionally, the reinsulating process also reduces the energy usage as the unit does not have to work overtime to maintain temperature; therefore, potentially reducing overall energy costs. 

As a result of improved walk-in performance, the unit also provides a safer environment in terms of food safety as liner panels allow the unit to maintain the correct temperature to store food. 

Lastly, thermal liner panels have the potential to extend the life of the walk in by up to five years.

In conclusion, thermal liner panel systems provide an efficient solution to reinsulating and refacing damaged panels without having to shut down to repair and replace, restoring your walk-ins to like new condition.
