How to Stay Warm In a Cold Warehouse


Learning how to stay warm in a warehouse can feel like an impossible task. With large loading doors opening and closing frequently during the day and night, it’s difficult to keep your warehouse – and your employees – warm during winter. This is problematic from a facility management standpoint, but it can also create a less than comfortable workspace. There are ways, however, to combat the cold in your warehouse during the winter, lower your utility bills, improve productivity, and provide a comfortable environment for your employees.

Keeping the Warehouse Warm

It is important to have realistic expectations when trying to keep warm in a cold warehouse. In colder climates, it is not going to be possible to keep the temperature inside the warehouse at a comfortable 72 degrees. The loading bay doors will need to be open regularly, which will allow cold air to come into the warehouse and lower the temperatures. However, there are ways that you can make the warehouse warmer and more comfortable for people to work in.

1. Check the Doors

If the loading doors don’t need to be open all the time, make sure that they are closed. This is the easiest way to keep your warehouse at a more comfortable winter temperature. Doors that need to be open on a more constant basis can be fitted with plastic sheeting that will allow easy movement through the door, but provide some barrier from the elements outside. Before it gets too cold, it’s also a good idea to make sure that your loading area doors are well sealed. This will reduce drafts, making a better barrier for your warehouse when the doors are closed. Finally, make sure that your doors are maintained and the motors to lift the doors are functioning properly. This will reduce the likelihood that a door will get stuck open when the weather is poor.

2. Improve Warehouse Airflow

Airflow patterns in warehouses can be challenging. There are a lot of barriers that disrupt smooth airflow through your warehouse, and high ceilings tend to hold on to the warm air. While we typically think of using fans and other air circulating tools to cool down a space, they can be equally as useful in keeping a space warm. Improving the way air moves through your warehouse can make a substantial difference in the overall climate in your facility. There are few ways that this can be accomplished.

  • Fans – this is a relatively inexpensive way to improve airflow in your warehouse. Using high volume low speed (HVLS) fans can help move warm air through your warehouse, and pull warm air away from the ceiling. Fans are low energy, so installing fans in your warehouse will not make a significant impact on your utility bills.
  • Warehouse Layout – Look at the configuration of your space. How are the shelves arranged? Do your aisles create wind tunnels? If your warehouse layout allows cold air to move easily from the doors to the rest of the building, it may be time to consider moving things around.
  • A Shelving Upgrade – This is probably the costliest way to improve airflow. If you have solid shelving, but could convert to low-profile wire shelving, you can greatly increase the airflow in your warehouse. These shelves aren’t practical for all warehouses, but they may be a good solution in the right facility.
  • Provide Adequate Lighting – Adequate lighting is essential to maintaining rates of productivity. They also help to warm up the environment – at least psychologically. Even if you’re not using lights that put off heat, the mere act of lighting up the warehouse appropriately can make the space feel warmer and more inviting. 

3. Use More Heaters

If your warehouse is still cold despite making other changes, you may just need to add more heaters. New radiant heaters are efficient and create a lot of heat for large spaces. Sometimes, adding more heaters is all you need to keep workers comfortable. You should also encourage workers to take breaks to warm up.

4. Service Your HVAC System

Finally, make sure that your HVAC system is ready for the winter. Have a HVAC professional visit your facility and give your system a good tune-up and service to ensure that it is functioning as efficiently as possible. It’s a good idea to do this annually to keep your HVAC system in good working order and to prevent possible outages. 

Keeping Your Workers Warm

You’ve done the first things to make the climate better in your warehouse. But it’s still not going to be as nice as an office. It will be cooler than other parts of your building, so you need to have things to help keep your workers warm and safe. Here are some tips for your workers on how to stay warm in a cold warehouse.

Educate Your Workers

Make sure your employees know how to work safely in the cold. This is especially important in places where there are a lot of people coming and going and the doors are open more often. Employees should know how to recognize the signs of cold stress, and there should be a rule about how long an employee can work in the cold. Employees should also know what kind of clothing and gear they need to wear so they stay warm and can work safely.

What you eat can also affect how warm you stay in cold temperatures. Eating foods with carbohydrates, proteins, natural fats and sugars helps. Drinking lots of fluids is also important. Sports drinks that have electrolytes are a good choice because they keep your body hydrated and give you energy. Some people think that drinking hot coffee will help them stay warm, but caffeine can actually make you more dehydrated. When you drink coffee, it makes your blood go to the surface of your skin which makes you lose heat from your body.

Engineering Controls

This sounds complicated but it really is quite simple. Provide your employees with places to get warm. This may be a heated office or breakroom in the warehouse, or just some good radiant heaters that they can stand near to warm up. You may also want to make sure that your employees have access to warm beverages like coffee or tea. These will warm them from the inside out.

Provide the Right Equipment

Knowing what to wear in a cold warehouse can also help to keep employees warm. There are no OSHA requirements that say you have to provide your workers with a coat, hat, gloves or ordinary winter clothing. However, as an employer, it’s in your best interest to make sure that your employees have what they need to work safely. This may mean providing a good warm coat, warm gloves, a proper winter hat, and insulated and waterproof boots. Winter wear for the warehouse may vary from person to person, but offering these options can keep folks happy. When your employees have the right equipment to do their job, be warm and comfortable, and are safe doing their job, your warehouse is more efficient and productive.

Cold Warehouse FAQ

What do you wear to a cold storage warehouse?

First, layers are key. Wear a base layer of thermal underwear followed by a shirt, sweater, and jacket. It is also important to wear gloves, a scarf, and a hat to keep your extremities warm. In addition, make sure to wear boots with good insulation and socks that will help to keep your feet warm. By following these tips to stay warm in warehouse for winter, you can stay warm and safe.

How cold do warehouses get in winter?

In winter, the temperature in warehouses can drop significantly below freezing. This is because warehouses are typically large, open spaces with high ceilings. The cold air sinks to the floor, and the lack of insulation means that the space is unable to retain heat.
