Do you have an idea of starting your own business? Cute flower shop on the corner? Or maybe a food-related company? Or you might be looking into joining the pharmaceutical business and start working with medical supplies? Regardless of the idea you have, chances are you will need a walk-in refrigerator. Next thing you know, you make a stop to the market to buy one, yet you leave it in confusion. 
Today we will guide you into entirely new and unexplored territory for you and explain a bit about one of the most critical aspects of walk-in refrigerators – R-value. Likely, you`ve probably heard the salesperson mentioning this, and we are here to explain everything about it. 

What is R-Value?

To put it in the simplest way possible, R-value is the quality of the insulation in your walk-in. The higher the number- the better.
The name itself is a quantified representation of the material’s heat resistance. As the years go by, the used foam deteriorates, and the R-value changes/lowers. Additionally, you should know that the R-value also depends on the thickness of the foam and its type.
The R-value of a walk-in refrigerator is usually noted as part of the model’s specification sheet.

Why is proper insulation important?

In the walk-in coolers industry, insulation is a crucial factor. Proper or improper insulation has a direct impact on the walk-in efficiency and, therefore, on the utility costs and longevity of the walk-in unit elements.
Higher R-Value means better insulation, so your walk-in doesn’t need to work hard to keep the temperature steady and the area cool enough. In the long run, this means that the walk-in components will last a long time with far less maintenance/replacement costs.

What R-Value do you need?

Choosing the R-Value that your business needs depend on a variety of different factors. Commonly the standard walk-in coolers have a 25 R-Value. However, if you want the inside of your walk-in to have lower constant temperature-that means greater insulation, which means greater R-Value. Comparative, freezers R-Value is 32 or in translation that is four inches of insulation.

Types of Refrigerator Insulation

Now that you do know what R-Value is and why it is so essential, the question of how to choose the proper insulation type arises. There are many types on the market, but you should always go for lightweight, affordable material. Nowadays, most commonly used materials and most broadly accepted are the man-made materials such as polyurethane and extruded polystyrene.

Conclusion

Knowing all this is vital, especially if you want to make your walk-in unit as energy efficient as you possibly could. Consider insulation as a crucial behind the scenes component which cannot be forgotten nor ignored.
