A cold store dock door is an insulated loading bay door built for chilled or frozen buildings, usually a sectional door with thick insulated panels or a high-speed door with an insulated curtain. It differs from a standard dock door in its thermal breaks, extra seals and, on freezer docks, heating in the frame or seals so that ice cannot lock the door shut or tear the seals.
Where does this fit at a dock in Mid Glamorgan?
Converting an ambient unit in Mid Glamorgan to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers. Any cold store dock survey in Mid Glamorgan is carried out with the store running, so we can see ice, seals and traffic as they really are.
When an older cold store in Mid Glamorgan has a door that has been repaired many times, a planned replacement can be timed for a quieter trading period.
Any project involving cold store dock doors at a working site in Mid Glamorgan takes planning. We survey free of charge, quote a fixed price in writing, and then agree a programme that keeps as much of the dock running as possible. Specialist installation engineers carry out the work under our management, out of hours if that suits you better. On completion we test each item, show your team how it operates and leave the documentation with you.
Do cold store dock doors have to meet building regulations?
Yes, a new or replacement cold store dock door is still a vehicle access door, so building energy rules apply alongside workplace safety law and product standards.
- England: Approved Document L (2021) Volume 2 limits the U-value of vehicle access and similar large doors to 1.3 W/m²K in new and replacement work. Cold store doors are normally specified to perform better than that to protect the store.
- Wales, Scotland and Northern Ireland: Approved Document L for Wales, Section 6 of the Scottish Building Standards Technical Handbook and Technical Booklet F2 in Northern Ireland apply. We confirm the figure for your nation and project.
- Power failure: under the Workplace (Health, Safety and Welfare) Regulations 1992 in Great Britain, or the 1993 Northern Ireland regulations, a powered door must be operable by hand where needed for health or safety, unless it opens automatically when power fails.
- Standards: BS EN 13241 for the door and BS EN 12453 for powered operation.
How does a cold store door work with the shelter and leveller?
On a cold store dock the door, shelter and leveller should work as one system, with the door opening only once the trailer is sealed against the building and closing before the seal is released.
A typical sequence is:
- The trailer reverses onto the bumpers and is held by a restraint, or the driver's keys are taken.
- The shelter inflates or the seal compresses around the trailer.
- The door opens and the leveller lip is lowered onto the trailer bed.
- Loading takes place inside a sealed link between store and trailer.
- The leveller is stored, the door closes, then the shelter releases.
Interlocks make this sequence automatic, so the door cannot be left open with no trailer present. Insulated leveller platforms and seals around the pit also reduce cold loss through the floor of the bay.

Planning, building control and safety law in Wales
HSE regulates workplace safety in Wales. Loading bays in Mid Glamorgan need doors that meet regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, work equipment maintained under PUWER, and safeguards that stop vehicles leaving the dock too early. We check what applies at survey and build those measures into the design.
Questions
Can you work alongside our main contractor on a new build in Mid Glamorgan?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
Is VAT included in your guide prices for cold store dock doors?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Mid Glamorgan as everywhere else: for cold store dock doors, it is £4,800 to £9,500 per door, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
Will a new door reduce our refrigeration load?
A better-sealed, better-insulated door that stays shut except when a trailer is docked reduces the warm air entering the store, which is a significant source of load at a cold store dock. We cannot promise a figure, because results depend on your store, traffic and the rest of the dock, but the mechanism is well understood.
Do heated door frames use a lot of power?
Frame and seal heaters are low-power elements designed to keep surfaces just above freezing rather than to heat the dock. Many can be controlled by a thermostat so they only run when needed. We set out the supply required in the written quote so it can be planned before installation.
