Overview: Air curtains and plastic strip curtains both protect commercial openings, but they work very differently. Here’s how to choose the right solution for your facility! 

Keeping a commercial opening protected without slowing operations down is a challenge every facility manager knows well.

Whether it’s controlling temperature, keeping out insects, or maintaining separation between work zones, the solution installed at an opening directly affects how efficiently a facility runs. Two of the most commonly compared options are air curtains and plastic strip curtains, and while both serve similar purposes, they are built for very different environments and operational demands.

Here’s what facility managers need to know before choosing between them.

What Is an Air Curtain and How Does It Work?

An air curtain is a device mounted above a doorway or opening that projects a continuous stream of air downward, creating an invisible barrier between two environments. That airflow separates indoor and outdoor conditions without any physical obstruction in the opening.

What Are Air Curtains Typically Used For?

Air curtains are commonly installed in:

• Retail and commercial entrances with high foot traffic

• Food service and restaurant environments

• Warehouses and distribution centers with frequent door activity

• Cold storage facilities requiring temperature separation

• Manufacturing plants managing insect and dust control

What Are Plastic Strip Curtains and How Do They Work?  

Plastic strip curtains, also called PVC strip curtains, are overlapping strips of flexible plastic suspended in a doorway or opening. People, equipment, and forklifts pass through by pushing the strips aside, which then return to position after passage.

Where Are Plastic Strip Curtains Most Commonly Used?  

Plastic strip curtains are a practical solution for:

• Warehouse and industrial openings with forklift traffic

• Cold storage and freezer room entrances

• Food processing and clean room environments

• Noise and dust separation between work zones

• High-traffic internal doorways where a solid door isn’t practical

How Do Air Curtains and Plastic Strip Curtains Compare?  

Both solutions offer temperature separation, but they work differently under different conditions.

Air curtains create an invisible thermal barrier that works well for frequently used openings where physical contact with a barrier isn’t practical. They are particularly effective at commercial entrances where customers and staff move through continuously.

Plastic strip curtains provide a physical seal that can be more effective at maintaining temperature in cold storage and freezer environments, especially when traffic is intermittent rather than constant.

Which Is More Energy Efficient? 

Air curtains consume electricity to operate the fan system, but they effectively reduce heating and cooling loss through open doorways, delivering strong energy efficiency in high-traffic openings. Plastic strip curtains require no power and provide passive insulation, making them a cost-effective option for facilities with moderate traffic and tight energy budgets.

Which Option Is Easier to Maintain?  

Plastic strip curtains have a clear advantage in maintenance simplicity. Individual strips can be replaced as they wear or become damaged without taking the entire system offline. Air curtains require periodic cleaning of the fan unit and housing but have fewer components subject to physical wear from daily contact.

Which Solution Is Better for Food Safety Environments?  

Both are used in food processing and food service settings, but for different reasons.

Air curtains are preferred at customer-facing and exterior entrances where insect control and hygiene are the priority. Plastic strip curtains are widely used in food processing facilities for zone separation, temperature control, and compliance with food safety regulations, provided they are maintained and cleaned regularly.

How Do You Choose Between an Air Curtain and a Plastic Strip Curtain?  

The right choice depends on several operational factors:

• Traffic volume — air curtains suit very high-traffic openings; strip curtains work well for moderate traffic

• Temperature requirements — strip curtains offer stronger passive insulation for cold storage

• Budget — plastic strip curtains carry a lower upfront and operating cost

• Hygiene standards — air curtains eliminate physical contact at the opening entirely

• Opening size — both solutions are available for a wide range of opening dimensions

Can Air Curtains and Strip Curtains Be Used Together?  

Yes, and in some facilities, combining both delivers the best results. A plastic strip curtain paired with an air curtain can provide enhanced temperature separation and insect control at openings where both passive and active barriers are beneficial.

Frequently Asked Questions (FAQs)  

Are air curtains effective at keeping insects out?
Yes. Air curtains are one of the most effective solutions for insect control at commercial entrances, creating a continuous airflow barrier that prevents flying insects from entering the facility.

How long do plastic strip curtains last?
Lifespan depends on traffic volume and environmental conditions. In high-traffic industrial settings, individual strips typically need replacement every one to two years, though the overall system can last considerably longer with proper maintenance.

The Right Solution Depends on Your Facility’s Needs  

Air curtains and plastic strip curtains are both effective, but neither is the right answer for every opening. The best choice comes down to traffic volume, temperature requirements, budget, and the specific operational demands of the space.
