Walk-in floor insulation for your freezer/cooler is critical in the design and installation. The flooring insulation you install or do not install could make all the difference in your walk-in. Insulation helps and works with your refrigeration box and equipment in a number of ways. One way is it helps your walk-in maintain the proper temperature and can help keep your inventory safe and stable. If you are a food processing plant or a laboratory, you could be storing items in your walk-in that are worth a lot of money. Without proper insulation, cool air is able to escape from your walk-in and warm air is able to penetrate it – causing fluctuating temperatures and humidity levels. Providing floor insulation helps keep temperatures stable and secure which in turn lowers the operating costs of the refrigeration equipment.
If your walk-in is installed above another room or floor in the facility or building, floor insulation is essential to avoid condensation build-up in the material between the two rooms or floors. Condensation can lead to serious mold problems over time and can be avoided by insulating the refrigeration flooring. Long term buildup of moisture and condensation can also damage components of the building. If there are cracks in the flooring insulation you install, moisture will seep into those cracks, freeze and then expand.
If your walk-in is located in a warmer environment (such as a warehouse, kitchen, outside) an insulated floor helps maintain proper temperatures.
If you decide to ditch flooring insulation, concrete flooring is the way to go. Concrete with vinyl, resin, or tile on top of it also works for walk-ins without insulated floors. These materials do an acceptable job of protecting your inventory from outside temperatures.
Choosing a good foundation and floor for your walk-in is extremely beneficial. Not only does it keep the cost of running your walk-in down but it protects both your products and your employees. With proper flooring, mold growth is kept to a minimum and the risk of accidents from slippery floors is kept down.
According to the National Floor Safety Institute, falls cause the highest number of employee injuries out of all workplace accidents, with wet floors responsible for 10 percent of those occurrences. In addition to causing a slip hazard, slippery floors make it difficult to safely maneuver racks, carts, and pallet jacks through the walk-in. Moisture can also condense on perishables and shorten their shelf-lives.
