PVC Strip Curtain Width and Overlap Guide

PVC strip curtain width and overlap are two of the most important factors when selecting the correct strip curtain for warehouses, factories, cold rooms, and industrial doorways. Choosing the correct PVC strip curtain width and overlap ensures the curtain provides an effective barrier while still allowing easy access for personnel, forklifts, pallet trucks and equipment moving through the opening.

How to Choose the Correct Strip Width

The height of the doorway is one of the main factors that determines the correct strip width. If the strip width is too narrow for a tall opening, the strips may curl or fail to provide proper coverage at the bottom. As a general rule, the taller the doorway, the wider the strip should be to maintain stability and durability.

Typical recommendations for PVC strip curtain width and overlap based on doorway height include:

• 200mm strips – Suitable for interior openings up to 3 metres high and exterior openings up to 2.5 metres.

• 300mm strips – Suitable for interior openings up to 4.5 metres and exterior openings up to 3.5 metres.

• 400mm strips – Suitable for interior openings up to 5.5 metres and exterior openings up to 4.5 metres.

For example, if you have a doorway that is 4 metres high in an indoor warehouse environment, a 300mm strip width is typically the ideal choice.

Choosing the Right Strip Thickness

When selecting strip thickness, it is important to consider what type of traffic will be passing through the curtain.

• 2mm thickness – Ideal for pedestrian traffic such as staff walkways or walk-in coolers.

• 3mm thickness – Suitable for heavier foot traffic and moderate industrial environments both indoors and outdoors.

• Ribbed PVC strips – Designed for heavy industrial traffic and areas exposed to strong winds or forklift activity.

Ribbed materials are generally recommended for high-traffic industrial doors because they offer improved durability and reduced surface damage compared to smooth strips.

How to Choose the Correct Strip Overlap

The correct PVC strip curtain width and overlap also depends on the type and frequency of traffic moving through the doorway.

Personnel Doors

For doorways used mainly by people, smaller strips with minimal overlap are usually sufficient. In many cases, 200mm strips with a light overlap provide easy access while still maintaining airflow control.

Pallet Truck Traffic

When pallet trucks and goods are regularly moved through the opening, larger strips are required. 300mm or 400mm strips with 35–50% overlap are commonly used to provide better durability and coverage.

Forklift Traffic

Doorways used by forklifts experience the highest level of impact and wear. In these environments, large and durable strips are recommended. 300mm ribbed strips or 400mm strips with around 50% overlap provide the strength required for heavy industrial traffic.

Understanding the correct PVC strip curtain width and overlap for your doorway will help ensure long-lasting performance, improved energy efficiency and better environmental control within industrial facilities.
