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.
Where does this fit at a dock in Bonnyrigg?
A chilled distribution centre in Bonnyrigg opens its dock doors many times a shift, so the door specification matters far more than at an ambient bay. Food manufacturers in Bonnyrigg moving finished product into frozen storage need doors that resist ice and close quickly behind each forklift or trailer movement.
Any cold store dock survey in Bonnyrigg is carried out with the store running, so we can see ice, seals and traffic as they really are.
The survey is free, the quote is written and the price is fixed: that is how every installation in Bonnyrigg 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.
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.
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 does the free survey cover?
- Age and condition of the equipment already in place
- Control positions, isolators and any existing interlocks
- Traffic routes for vehicles and separation of pedestrians
- Power supply at each bay, including three-phase availability
- Whether planning, building control or a building warrant may be needed
- Forklift and pallet truck loads crossing the leveller platform
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 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 Bonnyrigg, 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.
Questions about cold store dock doors in Bonnyrigg
Do you cover Bonnyrigg for cold store dock doors?
Yes. We take on cold store dock doors for businesses in Bonnyrigg and across Edinburgh and the Lothians. 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 Bonnyrigg 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 Bonnyrigg?
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 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.
