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.
How does this suit sites in Dunoon?
A chilled distribution centre in Dunoon opens its dock doors many times a shift, so the door specification matters far more than at an ambient bay. For a packhouse in Dunoon handling fresh produce, a well-sealed chilled dock door helps keep warm air out of the store once produce has been cooled.
Converting an ambient unit in Dunoon to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
It starts with a free site survey in Dunoon, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the documentation.
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.
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 Scotland; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Power supply at each bay, including three-phase availability
- Bumper position and wear or damage on the dock face
- Wind exposure at the dock, which affects door and shelter choice
- Clear opening width and height for each door
- Lighting inside trailers and at the dock face
- Asbestos register and any other site hazard information
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.
Insulated sectional cold store door
Thick insulated panels with thermal breaks and full perimeter seals, the usual choice for chilled and frozen external dock openings that also need to be secure overnight.
Regulations and approvals in Scotland
In Scotland, building work such as forming a new opening or a dock leveller pit may need a building warrant from the local authority before it starts. For sites in Dunoon, external structures such as loading houses or canopies may also need planning permission from the council. We check what applies at survey and factor any approvals into the programme.
We cover Dunoon by arrangement. The survey and written quote stay free: for remote and island sites we often start from your photos, drawings and a video call, then confirm measurements on site. Travel and any accommodation needed for the installation are shown as separate lines in the fixed quote.
Questions about cold store dock doors in Dunoon
How long does installation take at a site in Dunoon?
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.
Can you work alongside our main contractor on a new build in Dunoon?
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 the site survey in Dunoon free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
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.
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.
