A strip curtain is among the simplest tools for keeping cool air in, dust out and noise down, yet buyers often choose it by price alone and then wonder why it tears, yellows or fails to stop drafts. Customers who ask Aircon Engineers about PVC strip curtains price are better served by a different first question: what does the doorway need the strips to do? This guide connects thickness, width, overlap and material to the job so that the quote you accept matches the problem you have.
How a strip curtain works
A strip curtain hangs from a rail above the opening. Flexible strips overlap one another, so people and vehicles can pass through while the strips fall back into place. The overlap forms a partial seal that reduces air exchange, limits the movement of dust and insects and softens noise between zones.
Compared with a solid door, a strip curtain costs little, needs no moving parts and can be fitted in an hour on many openings. Its limitation is that it is a partial barrier. It reduces air loss instead of stopping it entirely, which is why many sites pair it with another measure at the busiest entrances.
Thickness and width, the two numbers that decide performance
Strips come in a range of thicknesses and widths. Thin strips are light and suit low-traffic doorways such as office pantries and small cold rooms. Thicker strips are heavier and suit warehouses, loading bays and freezer entrances where forklifts or trolleys pass often. Width affects the overlap: wider strips give a better seal but need more force to push through.
As a rough guide, choose the thinnest strip that still hangs straight and recovers quickly. Anything heavier than needed adds cost and makes passing through harder. Anything lighter than needed will flutter in the draft and leave gaps. Ask the supplier to match the strip to the door height and the traffic type.
Material grades and temperature
Standard PVC works well for ambient and moderately cool rooms. For freezers, cold-resistant grades stay flexible at low temperatures, while normal grades stiffen and crack. For welding bays, special coloured strips protect nearby workers from arc light. Anti-static and insect-repellent grades exist for sensitive areas. Using the wrong grade is a common cause of early failure.
Ask for the grade by name and the minimum working temperature. A transparent strip will cloud over time with dust and sunlight, so plan for cleaning or replacement every few years. A site with strong sun on the doorway may benefit from a UV-stabilised grade.
Overlap, rails and fittings
The standard overlap is about half the strip width, though some sites choose a larger overlap for better insulation. The rail and hardware matter too. A stainless steel or powder-coated rail is stronger and lasts longer than a thin painted one. Clips and bolts should be corrosion-resistant if the doorway is exposed to moisture or cleaning chemicals.
Measure the opening carefully, including any ledge, sensor or door frame, and note the height from floor to rail. Strips should hang a few centimetres above the floor, close enough to seal but not so low that they drag. A good supplier will confirm the dimensions before manufacturing.
Pairing with other solutions
At entrances with heavy traffic, a combination often works better than a single product. For example, a commercial air curtain above the door plus strip curtains below can reduce loss of cooled air, keep dust outside and manage insects. Our blog on air curtain price in India and what actually changes the quote explains how to size the unit for such a setup, and the article on commercial air curtains and how they cut cooling loss at entrances shows what savings to expect.
Insect control in food and clinic areas
Kitchens, bakeries and clinics often add insect control at the entrance. A tool such as an electric fly killer machine attracts and removes flying insects, and strip curtains reduce the chance that they enter in the first place. Position the device away from food preparation surfaces and where it is not visible from the street, and clean the collection tray regularly.
Installation and maintenance
Fix the rail firmly into a solid lintel and check that the strips hang evenly. Test the traffic: forklifts should pass without catching, and people should push through easily. Clean strips with mild soap and water every month, and replace damaged strips quickly. Tears let air through and can snag on trolleys.
For a quick audit of your own doorway, the PVC strip survey checklist lists measurements and questions to prepare before you request a quote.
Common mistakes with strip curtains
One mistake is hanging strips too close to a heater, a hot oven vent or a sunny glass door, which can soften or discolour them. Another is choosing very wide strips for a narrow opening so that people struggle to pass. A third is ignoring cleanliness: strips used in food areas should be washed on a schedule, and any strips that stay cloudy after cleaning should be replaced. Finally, remember that forklift drivers need visibility. Choose clear or lightly tinted strips with visible bands at eye level where traffic moves, so that collisions are less likely and staff can see both sides of the doorway.
Questions to ask before ordering
What grade is quoted and what is its working temperature range? What thickness and width are proposed, and why? What is the overlap? Is the rail included, and what is it made of? What is the delivery time? Is installation included? What is the warranty? Written answers make comparison easy and prevent surprises on delivery.
Final thoughts
A strip curtain is cheap compared with the energy and hygiene problems it solves, but only if it is specified correctly. Match the grade and thickness to the doorway, check the fittings and maintain it. To ask for a site visit or a written quotation, use the contact page of Aircon Engineers and share the door size, traffic type and temperature of the room.
