Air curtains for shops and retail outlets

Air curtains are hugely beneficial for shop entrances as they effectively create an invisible barrier of air that separates the indoor and outdoor environments. This stops heated air from escaping in the winter and air conditioned air from leaving during the summer. Installaing air curtains on busy shop entrances will help reduce an operator's energy consumption and costs from HVAC systems.

Maintaining a more pleasant internal environment for customers makes them more comfortable and increases the average browsing time. This in turn has an immediate impact at the till, as happy customers will buy more. Pleasant indoor environments are also very beneficial for staff, particularly those who are stationed close to entrances. This not only improves working conditions but could also reduce absenteeism. 

It has been proven that a shop with an open doorway will increase passing trade. However, this is only practical in the winter with an air curtain to maintain warm internal conditions.

Air curtains will prevent airborne pests from entering. This is particularly useful for bakeries, butchers or other food retailers, as air curtains will maintain a more hygienic internal atmosphere without needing to install chain fly screens. A correctly sized air curtain will also prevent dust and airborne pollutants from blowing into a store every time a customer enters or leaves.

In summary, fitting an air curtain above a shop doorway saves money on climate control, creates a more pleasant internal environment for customers and staff, and helps maintain a more hygienic, cleaner internal environment.


  • An air curtain on a retail doorway should be wide enough to prevent any air leakage at the edges and powerful enough to create a seal at the floor. Air velocity at the further point from the air curtain should be at least 2m per second to achieve an efficient thermal barrier.

    Heated air curtains are always recommended for shops, as they create a more comfortable environment. Horizontal mounting above a doorway is more typical in retail settings than vertical mounting beside a doorway. Putting an air curtain above a shop doorway keeps it away from customers and prevents HVAC appliances taking up valuable floor space.

  • Yes. By reducing heat loss in the winter and stopping expensive air conditioned air from escaping in the summer, air curtains will reduce energy bills. Return on investment should also factor in improvements in passing trade and enahced sales through maintaing a more comfortable atmopshere.

  • Modern air curtains are relativly quiet in operation, but it will depend on the model and power of the fan. High doorways may require more powerful, and therefore noisier, fans to create an effective thermal barrier. Your JS AIr Curtains expert advisor will be able to provide information on noise levels for any chosen model.

  • A product marketed as an "overdoor heater" typically has a less powerful fan and therefore has a lower capital cost. Air curtains should be powerful enough for the air to be travelling at 2m per second when it hits the floor. This is an effective thermal barrier and is what an air curtain should deliver.

    Overdoor heater may provide some addition heat to a shop but rarely can prevent cold air entering and hot air escaping from an open doorway. They are also frequently supplied in lengths less than the doorway's width so air can leak in around the edges of an entrance.

Benefits of installing air curtains on shop entrances:

  • Keeps heated air in and cold air out during the winter
  • Improves passing trade by allowing doors to remain open
  • Creates more comfortable environments to increase customer browsing
  • Improves working conditions for staff
  • Keeps pests out for more hygienic operations
  • Prevents dust and outdoor pollution from entering
  • Reduces air con bills by keeping chilled air inside

Cannon Hall Garden Centre

Deborah Robinson

Owner

“The entrance vestibule always felt so cold; not very welcoming for our customers. We needed a warming solution that could be easily retrofitted, complemented our existing décor and provided adequate heating to increase the comfort level within the garden centre. JS Air Curtains was the first manufacturer to respond to my enquiry. Its Mini Optima met our budget and proved ideal. The air curtain from JS was a perfect and easy fit while looking stylish and unobtrusive.”

Reynolds Furniture

Matthew Reynolds

Finance Director

“The renovation of our furniture store was designed to create a modern environment where our customers would feel comfortable and at ease making their buying decisions. It was important that the air curtains looked great, to match the aesthetics of our décor, as well as maintaining the ambient temperature. We have been very pleased with the result and the air curtains have performed well so far, keeping our customers cool over the hot summer. We are confident they will continue to do their job through the colder months to come.”

Membury Services

Ray Drinkwater

Facilities Manager

“Without the air curtains the doors acted like a wind tunnel with the cold air blowing right through. The air curtains from JS were recommended by Russell Air Conditioning and have done a great job in stopping the cold air entering.”

John Lewis

Stuart Watson

Engineering Manager

“Our specification included both high performance and critical environmental requirements. We also needed the air curtains to fit seamlessly with security curtains that sit above the entrances, to blend in with the décor of the stores. Our M&E consultants suggested JS’ Zen air curtain because the range was diverse and flexible, and could provide the ideal model in each case to meet the differing conditions at the four stores.”
