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 Derry/Londonderry?
For a packhouse in Derry/Londonderry handling fresh produce, a well-sealed chilled dock door helps keep warm air out of the store once produce has been cooled. When an older cold store in Derry/Londonderry 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 Derry/Londonderry to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
Any project involving cold store dock doors at a working site in Derry/Londonderry takes planning. We survey free of charge, quote a fixed price in writing, and then agree a programme that keeps as much of the dock running as possible. Specialist installation engineers carry out the work under our management, out of hours if that suits you better. On completion we test each item, show your team how it operates and leave the documentation with you.
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 much does a cold store dock door cost?
A cold store dock door typically costs £4,800 to £9,500 per door, excluding VAT, supply and fit. Chilled docks usually sit lower in that range than freezer docks, because freezer doors need more insulation and frame heating.
Price is mainly driven by:
- Operating temperature: chilled, frozen, or a door between two temperature zones.
- Door type: insulated sectional, insulated high-speed, or both at one opening.
- Heating: heated frames, heated bottom seals or threshold heating to stop ice forming.
- Panel thickness and thermal breaks: thicker panels and better breaks reduce condensation and heat gain.
- Controls: faster operators, interlocks with shelters and levellers, and automatic closing.
- Working conditions: installing in a live cold store often means out-of-hours work and temporary screening.
We price each door after a free site survey, and the written quote fixes the cost.
The same published guide range applies across Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.
What we look at on site
- Whether planning, building control or a building warrant may be needed
- Temperature requirements for chilled, frozen or ambient goods
- Traffic routes for vehicles and separation of pedestrians
- Bumper position and wear or damage on the dock face
- Yard gradient and the slope of the approach to the dock
- Gaps around trailers where heated or chilled air escapes
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.
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.
What do the rules in Northern Ireland mean for the work?
Energy requirements for non-dwellings in Northern Ireland are set by Technical Booklet F2. For new or replacement loading bay doors in Derry/Londonderry, we confirm the figure that applies to your project and check what applies at survey, rather than working to rules from elsewhere in the UK.
Questions about cold store dock doors in Derry/Londonderry
Do you cover Derry/Londonderry for cold store dock doors?
Yes. We take on cold store dock doors for businesses in Derry/Londonderry and across County Londonderry. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
Is the site survey in Derry/Londonderry 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.
How do you price cold store dock doors for a site in Derry/Londonderry?
Guide budgets for supply and fit are £4,800 to £9,500 per door, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
Can a standard sectional door be used on a chilled dock?
A standard insulated sectional door can work on a chilled dock if its panels are thick enough and its seals are in good condition. For frozen docks it is not usually suitable, because it lacks the thermal breaks and frame heating needed to stop ice forming. We advise on the right specification after surveying the store.
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.
