Temperature spikes cost money, compromise product safety, and put compliance at risk. The doors you fit at every access point are directly responsible for how well your facility holds temperature, and a poor choice here creates problems that no amount of HVAC investment will fully solve.

At Kenfield, we've been manufacturing cold room door solutions from our Birmingham facility since 1983. That's over 40 years of working with some of the most demanding cold chain operators in the UK and internationally. Here's why facilities managers, refrigeration engineers and logistics operators keep coming back to us.

Kenfield's cold room range is focused. We don't dilute it with products we can't stand behind. There are two solutions, and both exist for good reason.

The K750 Energy Door: Our Flagship Flip Flap Door

The K750 is our patented, award-winning flip flap door, and it's the product we're best known for. With over 35,000 installations across leading supermarkets in the UK, Europe and the USA, it has a track record that's hard to argue with.

It's designed specifically for temperature-controlled environments where doors are opened frequently. The flexible, self-returning panels allow staff to pass through quickly without having to manually open and close a door, which matters enormously in high-traffic cold storage areas where every second of door-open time is warm air coming in.

Key features include:

• Lightweight construction that's easy on staff and reduces cold room wear

• No external frame, which simplifies installation and maintenance

• No finger trap, which is a genuine safety benefit in busy operations

• A hinge guard for added protection

• Manufactured from heavy-duty PVC or polyurethane material depending on your specification

• Available in single or double configurations

• The K750 can offer up to 50% energy usage reduction compared to using an unhooked (or in poor condition) PVC strip curtain. 

It's also worth being honest about what it won't do. The K750 works best as part of a well-maintained system. If your cold room has pre-existing icing problems or underlying refrigeration faults, address

The K2 Insulated Strip Door Curtain: Cost-Effective Cold Room Curtains

The K2 is our insulated cold room curtain, and it occupies a different part of the market. If the K750 is the solution for high-traffic primary access points, the K2 is the practical option for pedestrian doorways, lighter-use areas, or anywhere you need a simple thermal barrier without the full specification of a rigid door.

Constructed from heavy-duty PVC with a lightweight fibre insulation layer between the outer skins, it offers genuinely good thermal resistance. It's not just a standard strip curtain. The insulated construction makes a measurable difference to warm air ingress compared with clear PVC-only alternatives.

Key features include:

• Available in sizes up to 3.5m high

• Welded seams for durability

• Integrated vision panel so staff can see through before pushing through

• No finger trap

• Choice of colour, and sign-writing available to order

• Sliding track option for appropriate environments

• No external frame

• Lower section can be trimmed to fit your exact opening height

• Continuous rounded edge on strips for staff friendly use

It's used in walk-in cold rooms, freezers and refrigerated vehicles. It's also commonly used as a secondary thermal barrier behind a primary cold room door, which adds another layer of temperature protection with minimal additional cost.

There are plenty of door suppliers. Here's what we think matters when you're making a decision on this.

A Proven Track Record in Real Environments

Over 35,000 K750 installations across UK, European and American supermarkets is not a marketing figure. It's a practical one. Major retailers including Tesco, Sainsbury's, Asda, Aldi, Morrisons and Iceland have chosen Kenfield products for their facilities.

If your cold room doors need to perform in a demanding, high paced environment, these are the environments our products have already been tested in.

Custom-Built to Your Specification

Every cold room is different. Opening dimensions vary. Traffic levels vary. Temperature requirements vary. That's why every Kenfield cold room door is made to order, configured to your exact specification. You can use our online door configurator to start the process, or speak to our sales team directly if your requirements are more complex.

We don't push you towards a product because it's easiest for us. We help you find what actually works for your facility.

ISO 9001 and ISO 14001 Accredited

Quality management and environmental management are both certified through independent accreditation. ISO 9001 means our processes are consistent and audited. ISO 14001 reflects our commitment to reducing environmental impact, which is increasingly relevant for businesses with sustainability targets.

These aren't just certificates on a wall. They're a useful signal that our manufacturing processes are built on something reliable.

British Manufacturing

Our products are designed and manufactured in Birmingham. That means we control quality throughout the process, and it means turnaround times are not subject to the delays and logistics complications that come with imported products. It also means our sales team and technical support team are in the same building as production, which makes answering technical questions faster and more accurate.

An Expert Team That's Worked in This Industry Since 1983

Four decades gives you a lot of accumulated knowledge. Our sales team understands cold chain environments, food retail operations and logistics facilities. When you call us with a specification question, you get a useful answer, not a brochure forwarded by email.

Which Cold Room Door Solution Is Right for You?

Here's a straightforward way to think about it.

If your access point handles high-volume staff traffic, and maintaining temperature in a primary cold room is the priority, the K750 Energy Door is the product to look at. It's been specified for exactly this application thousands of times.

If you're looking for a cost-effective thermal barrier for a lighter-traffic access point, a pedestrian doorway, a refrigerated vehicle, or a secondary layer of protection behind a primary door, the K2 Insulated Strip Door Curtain is the more practical fit.

If you're not sure, give us a call. We'll ask the right questions and give you a straight answer.
