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 Wrexham?
When an older cold store in Wrexham 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 Wrexham opens its dock doors many times a shift, so the door specification matters far more than at an ambient bay.
Converting an ambient unit in Wrexham to chilled storage usually means replacing standard dock doors with insulated ones and sealing around the trailers.
The survey is free, the quote is written and the price is fixed: that is how every installation in Wrexham begins. We then manage the work from start to finish. Fitting is carried out by specialist installers under our management, phased so the operation keeps moving, and nights or weekends can be booked by arrangement. On the final day we test the equipment with you and hand over the operating and maintenance information.
How can a cold store door be replaced without losing temperature?
A cold store door can be replaced with very little temperature loss if the work is planned around the store, with the opening screened and the fitting done in one continuous visit.
On a live cold store we usually:
- schedule the work for the quietest period, often overnight or at a weekend,
- fit a temporary insulated screen or strip curtain while the opening is exposed,
- remove ice from the old frame and threshold before fixing the new door,
- pre-assemble as much as possible so the opening is exposed for the shortest time.
From your side we need product moved back from the opening, any site permits for working in cold areas, and power for the operator and frame heaters. Heated frames typically need their own supply, which we set out in the quote. Our cold store loading bays guide covers planning the work in more depth.
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.
The same published guide range applies across Wales; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Drainage on recessed or sloping dock approaches
- Traffic routes for vehicles and separation of pedestrians
- How often each door cycles during a typical shift
- Gaps around trailers where heated or chilled air escapes
- Power supply at each bay, including three-phase availability
- Asbestos register and any other site hazard information
Options to discuss
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.
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.
Planning, building control and safety law in Wales
Sites in Wrexham follow the rules for Wales. Forming a new opening or dock pit may need Building Regulations approval, and loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey, so any approvals are understood before the programme is fixed.
Questions about cold store dock doors in Wrexham
Can you work alongside our main contractor on a new build in Wrexham?
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.
Will you deal with building control and planning for a project in Wrexham?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
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 Clwyd 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.
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.
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.
