PVC strip curtains for cold rooms and freezers are essential for maintaining temperature control, reducing energy loss, and ensuring safe access in chilled environments.

Standard industrial doorways can allow significant cold air escape, leading to:

  • Increased energy consumption.
  • Temperature fluctuations.
  • Frost build-up.
  • Reduced efficiency in chilled environments.

That’s why polar-grade PVC strip curtains are one of the most effective and cost-efficient solutions available.

In this guide, we explain what makes freezer applications different, why polar-grade PVC strip curtains are essential, and how to choose the best specification for your cold room or freezer doorway.

Why Cold Rooms and Freezers Need Specialist PVC Strip Curtains

Cold storage environments operate permanently at low temperatures, often below 0°C.

In these conditions, standard PVC material can become:

  • Stiff.
  • Brittle.
  • Difficult to pass through.
  • Less effective as a temperature barrier.

This reduces performance and shortens the curtain lifespan.

For freezer environments, the best solution is polar-grade PVC, specifically manufactured to remain flexible in sub-zero temperatures to -40°C.

What Are Polar-Grade PVC Strip Curtains?

Polar-grade PVC strip curtains are designed for chilled and freezer applications, remaining flexible at temperatures as low as -40°C, making it suitable for permanent freezer environments.

Unlike standard clear PVC, polar-grade material includes additives and softeners that ensure it remains:

  • Flexible.
  • Durable.
  • Effective at low temperatures.

This allows the strips to function properly even in permanently cold environments.

Best for:

  • Freezers.
  • Cold rooms.
  • Food storage facilities.
  • Temperature-controlled logistics centres.

Rayflex manufactures freezer-grade PVC strip curtains in the UK to suit all doorway sizes and cold storage requirements.

Key Benefits of PVC Strip Curtains in Cold Storage

Installing PVC strip curtains in cold rooms and freezers provides multiple operational benefits.

  1. Reduced Cold Air Loss

PVC strip curtains minimise the escape of chilled air when staff, roll cages or motorised traffic pass through.

This helps maintain stable temperatures and reduces compressor workload.

  1. Improved Energy Efficiency

By reducing heat exchange between environments, freezer strip curtains can significantly reduce energy consumption.

They are one of the most cost-effective cold room efficiency upgrades.

  1. Maintained Workflow and Accessibility

Unlike rigid doors, PVC strip curtains allow:

  • Hands-free access.
  • Continuous movement.
  • Fast entry and exit.

This is especially important in busy food distribution environments.

  1. Enhanced Hygiene and Containment

PVC strip curtains also help prevent:

  • Dust contamination.
  • Insect ingress.
  • Airborne particles entering food-safe zones.

This supports hygiene compliance in food production and storage facilities.

Best PVC Strip Curtain Specification for Cold Rooms & Freezers

Choosing the correct strip size and overlap is essential for performance. Freezer strip curtains typically require 50–100% overlap to maximise insulation and reduce cold air loss.

Recommended Strip Size for Freezers

Most cold room applications use:

200mm wide x 2mm thick Polar-Grade PVC

This provides a balance of access and insulation.

For Larger Openings or Vehicle Traffic

For larger doorways or pallet truck access, you may require:

  • 300mm wide x 3mm polar-grade strips.
  • Increased overlap for containment.
  • Heavy-duty rails for durability.

Forklift-access freezer doors often need specialist configuration.

Ribbed polar-grade strips are also available to improve durability and ease of movement for pallet and forklift traffic.

Rayflex can recommend the correct strip width, thickness and overlap based on traffic levels.

Freezer Strip Curtain Comparison Table

Cold Storage Application Recommended Strip Size PVC Grade
Walk-in Cold Rooms 200mm x 2mm Polar Grade PVC
Wide Cold Storage Openings 300mm x 3mm Polar Grade PVC
Forklift & Vehicle Access Freezers 400mm x 4mm Heavy-Duty Polar PVC

For the best results, strip overlap and fixing method should be matched to the environment.

Do PVC Strip Curtains Work Below Freezing?

Yes — but only if the correct grade is used.

Rayflex freezer-grade PVC is manufactured with a softener blend that ensures the strips remain flexible at temperatures permanently below 0°C, down to -40°C.

Standard PVC is not suitable for freezer environments, as it can harden and lose effectiveness.

Common Cold Storage Applications for PVC Strip Curtains

Freezer grade PVC strip curtains are widely used in:

  • Food processing plants.
  • Cold storage warehouses.
  • Pharmaceutical storage.
  • Supermarket distribution centres.
  • Walk-in freezers.
  • Chilled loading bays.

They provide an effective barrier while allowing continuous access while reducing cold air loss when freezer doors are open.

How to Get the Right Freezer PVC Strip Curtain Quote

Every cold room installation is different.

To specify the correct freezer strip curtain solution, consider:

  • Doorway width and height.
  • Temperature range.
  • Pedestrian or vehicle traffic.
  • Hygiene requirements.
  • Required overlap level.

Why Choose Polar-Grade PVC Instead of Standard PVC?

Standard PVC can harden and crack in sub-zero conditions. Polar-grade PVC is specifically engineered for freezer environments, maintaining flexibility and performance at temperatures as low as -40°C.

Frequently Asked Questions

What thickness PVC strip curtains are best for freezers?

Most freezer doorways use 200mm x 2mm polar-grade PVC, while high-traffic or vehicle-access openings may require 300mm x 3mm or 400mm x 4mm heavy-duty strips.

Are freezer-grade PVC strip curtains more expensive?

Polar-grade PVC can cost about 10% more than standard clear PVC due to specialist compounds added into the extrusion process, but it provides significantly better performance and lifespan in cold environments.

Do PVC strip curtains prevent frost build-up?

They help reduce warm air entering cold environments, which can minimise condensation and frost formation around freezer entrances and on compressors and air conditioning equipment.

Can forklifts drive through freezer strip curtains?

Yes — but heavy-duty polar-grade curtains are recommended for forklift traffic, with thicker strips and reinforced rails.

How quickly can freezer strip curtains be delivered?

Many stocked freezer-grade PVC strip curtain kits are available for fast UK dispatch, while made-to-order freezer solutions typically require 3–5 working days plus shipping.
