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.
Why do sites in Deal choose this?
Converting an ambient unit in Deal to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers. Any cold store dock survey in Deal is carried out with the store running, so we can see ice, seals and traffic as they really are.
For a packhouse in Deal handling fresh produce, a well-sealed chilled dock door helps keep warm air out of the store once produce has been cooled.
If you are planning cold store dock doors for a site in Deal, expect four stages. A free survey and fixed written quote come first. We then agree a programme with you, including any out-of-hours work. Specialist installation engineers carry out the installation under our management, with us as your single point of contact. Finally, the equipment is tested, your staff are shown how it works and everything is handed over with its documentation.
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 should a door be specified for a chilled dock compared with a freezer dock?
A chilled dock needs a well-insulated, well-sealed door, while a freezer dock also needs heating to stop ice forming in the frame and seals. The temperature difference across the door drives most specification choices.
- Chilled docks: an insulated sectional door at the thicker end of the common 40 to 80 mm panel range, good perimeter seals and a shelter or seal outside usually do the job.
- Freezer docks: thick panels, thermal breaks in the panel joints, heated side frames and a heated bottom seal, plus a fast operator to cut open time.
- Doors between zones: an insulated high-speed door often suits openings between a chilled marshalling area and a freezer, where traffic is constant.
- Vision panels: possible, but they reduce insulation and can mist, so many freezer docks leave them out.
A cold store door is only as good as the seal around the trailer, which is why we specify the door, shelter and leveller together.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Asbestos register and any other site hazard information
- Lighting inside trailers and at the dock face
- Scope to convert ground-level doors into docks or add lift tables
- Clear opening width and height for each door
- Working hours, shift patterns and windows for out-of-hours work
- Wheel guide positions and yard markings for reversing vehicles
Options to discuss
Dock interlocks
Controls that link the door to the shelter, leveller and restraint so the door only opens when a trailer is docked and sealed against the building.
Insulated high-speed door
A fast door with an insulated curtain for busy openings between temperature zones, where cutting open time matters more than maximum insulation.
Which rules apply in England?
Sites in Deal fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about cold store dock doors in Deal
Can you work outside our normal operating hours in Deal?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Deal site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
How long does installation take at a site in Deal?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
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.
What happens to a cold store door in a power cut?
In a power cut the door stops where it is and the frame heating switches off, so it must be possible to operate the door by hand. Powered dock doors normally have a hand chain, crank or release for this. We show your team how to use it at handover so the store can be closed up quickly.
