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 Greenford choose this?
Pharmaceutical and healthcare stores around Greenford with tight temperature ranges can pair an insulated dock door with interlocks so the opening stays closed until a trailer is sealed. Converting an ambient unit in Greenford to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
Any cold store dock survey in Greenford is carried out with the store running, so we can see ice, seals and traffic as they really are.
If you are planning cold store dock doors for a site in Greenford, 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.
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.
Why does ice form around a freezer dock door, and how is it stopped?
Ice forms when warm, moist outside air meets the cold surfaces of the door, frame and floor, and the moisture freezes. Over time it builds up in the seals and guides until the door jams or tears its seals.
Ice is controlled by tackling both the cold surfaces and the warm air:
- Heated frames and seals: low-power heating in the side frames and bottom seal keeps those surfaces above freezing.
- Threshold heating: stops the door freezing to the floor.
- A tight seal at the trailer: an inflatable dock shelter or a well-fitted seal keeps outside air away from the opening.
- Short open times: fast operators and interlocks mean the door is only open while a trailer is sealed to the dock.
Condensation dripping inside the store near the door is an early sign of the same problem and worth raising at survey.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- How drivers are prevented from pulling away too early
- Age and condition of the equipment already in place
- Access for deliveries, cranes or lifting equipment during installation
- Lighting inside trailers and at the dock face
- Temperature requirements for chilled, frozen or ambient goods
- Power supply at each bay, including three-phase availability
Options to discuss
Heated frames and seals
Low-power heating in the side frames, bottom seal or threshold that keeps contact surfaces above freezing so the door does not ice up or tear its seals.
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.
Regulations and approvals in England
In England, Approved Document L (2021) sets a limiting U-value of 1.3 W/m²K for vehicle access and similar large doors in new and replacement work. That shapes door specification for sites in Greenford, so we confirm the requirement for your project and check what applies at survey before recommending a door.
Questions about cold store dock doors in Greenford
Do you cover Greenford for cold store dock doors?

We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management.

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.
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 Greenford 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.
Do cold store doors need more frequent servicing?
Yes, cold store doors generally benefit from more frequent servicing than ambient dock doors. Low temperatures stiffen seals, stress springs and cables, and hide early ice build-up. Checking heaters, seals and operator settings before winter is particularly worthwhile. Servicing visits are chargeable and agreed in advance.
Can a cold store door be paired with a high-speed door?
Yes, cold store docks often pair an insulated sectional door on the outside with a fast door just inside it, or use an insulated high-speed door as the only door between zones. The right arrangement depends on traffic, security and how much space there is around the opening.
