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 Marlow?
A chilled distribution centre in Marlow opens its dock doors many times a shift, so the door specification matters far more than at an ambient bay. When an older cold store in Marlow has a door that has been repaired many times, a planned replacement can be timed for a quieter trading period.
Converting an ambient unit in Marlow to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
A single contact at Loading Bay Doors handles your project in Marlow from start to finish. The free site survey and fixed written quote come first, with no obligation to proceed. We then book the installation for times that suit the operation, including out of hours by arrangement, and manage the specialist engineers on site. At the end we commission and test the equipment, walk your team through it and provide 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.
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.

Survey checklist for your dock
- Dock height and the mix of trailers you load
- Yard gradient and the slope of the approach to the dock
- How drivers are prevented from pulling away too early
- Whether planning, building control or a building warrant may be needed
- Control positions, isolators and any existing interlocks
- Lighting inside trailers and at the dock face
Options to discuss
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.
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.
What do the rules in England mean for the work?
Workplace safety in England is regulated by HSE. For a loading bay in Marlow, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions about cold store dock doors in Marlow
How long does installation take at a site in Marlow?
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 outside our normal operating hours in Marlow?
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 Marlow 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.
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.
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.
