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.
Is this right for your site in Wiltshire?
When an older cold store in Wiltshire has a door that has been repaired many times, a planned replacement can be timed for a quieter trading period. A chilled distribution centre in Wiltshire opens its dock doors many times a shift, so the door specification matters far more than at an ambient bay.
For a packhouse in Wiltshire handling fresh produce, a well-sealed chilled dock door helps keep warm air out of the store once produce has been cooled.
Your loading bay stays our responsibility from the survey to the handover. In Wiltshire, the survey and written quote are free, and the quoted price is fixed for the agreed scope. Installation is carried out by specialist engineers working under our management, at times planned with you to protect your loading schedule. Out-of-hours work is available by arrangement. We finish by testing the equipment and handing over 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.
Towns we cover in Wiltshire
Each of the following towns in Wiltshire has its own page on cold store dock doors, covering how we work and what to send us.
Budget range for supply and fit. The written quote after a free survey is the fixed price. All guide prices.
What do the rules in England mean for the work?
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Wiltshire. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions
How long does installation take at a site in Wiltshire?
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.
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 Wiltshire 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.
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.
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.
