Temperature Control PVC Strip Curtains — Cold Rooms, Freezers and Heated Warehouses
PVC strip curtains are one of the most cost-effective methods of maintaining temperature zones in industrial and commercial environments. By creating a flexible barrier across doorways, they dramatically reduce heat transfer, cutting energy costs, maintaining cold chain integrity, and improving working conditions in both heated and refrigerated spaces.
Temperature Range by Grade
| PVC Grade | Min Temp | Max Temp | Application |
|---|---|---|---|
| Standard Clear | -5C | +40C | Ambient warehouses, heated areas, loading bays |
| Polar Grade | -25C | +40C | Walk-in cold rooms, chilled stores, refrigerated vehicles |
| Deep Freeze Grade | -40C | +40C | Blast freezers, IQF tunnels, deep freeze storage |
| Ribbed Polar | -25C | +40C | Cold rooms with vehicle access — extra insulation and rigidity |
Energy Savings: The Business Case
A typical 2.5m x 2.5m cold room doorway accessed 30 times per day, with a polar-grade twin track curtain, reduces air exchange by approximately 70%. Typical annual energy saving: £400 to £900 depending on electricity tariff and temperature differential. Curtain kit payback period: typically 6 to 18 weeks.
Installation Tips for Maximum Temperature Control
- Use twin track rails for maximum overlap and minimum air gap
- Increase overlap to 150mm per side in freezer applications (vs 100mm standard)
- Ensure strips reach to within 25mm of the floor to seal the bottom gap
- For wide openings, use 300mm wide strips rather than 200mm — fewer gaps between strips
- Replace cracked or brittle strips immediately — a damaged strip loses most of its sealing effectiveness
Frequently Asked Questions
What happens if I use standard PVC strips in a freezer?
Standard PVC becomes brittle and stiff below -5C, losing flexibility rapidly. In a freezer, standard strips will crack within weeks, creating gaps that defeat their purpose entirely and may create contamination hazards. Always specify polar-grade PVC for applications below -5C — for freezers below -20C, specify deep freeze grade rated to -40C.
Do PVC strip curtains comply with cold chain regulations?
Yes — PVC strip curtains are recognised as an effective cold chain management measure. For food businesses they help demonstrate compliance with the Food Safety (Temperature Control) Regulations 1995. For pharmaceutical cold chain under GDP, strip curtains at refrigerated store access points are a standard documented control measure. Use the correct grade for your temperature range and document maintenance in your temperature control records.
How often should I replace temperature control PVC strip curtains?
Replace strips when you see cracking or crazing of the PVC surface, yellowing that reduces clarity significantly, physical tears or holes, or visible gaps between strips. In busy cold rooms accessed 30 or more times per day, polar-grade strips typically last 2 to 4 years. Inspect monthly and replace damaged strips in temperature-critical applications immediately.
