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.
What matters for cold store dock doors in Lerwick?
Any cold store dock survey in Lerwick is carried out with the store running, so we can see ice, seals and traffic as they really are. Food manufacturers in Lerwick moving finished product into frozen storage need doors that resist ice and close quickly behind each forklift or trailer movement.
Converting an ambient unit in Lerwick 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 Lerwick 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 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 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.
The same published guide range applies across Scotland; access, out-of-hours working and site conditions are confirmed at the free survey.
Survey checklist for your dock
- Age and condition of the equipment already in place
- Traffic routes for vehicles and separation of pedestrians
- Escape routes and pedestrian doors close to the bay
- Power supply at each bay, including three-phase availability
- Forklift and pallet truck loads crossing the leveller platform
- Whether planning, building control or a building warrant may be needed
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.
Dock interlocks
Controls that link the door to the shelter, leveller and restraint so the door only opens when a trailer is docked and sealed against the building.
Regulations and approvals in Scotland
Doors and dock equipment installed in Scotland may carry the UKCA or the CE mark, and we pass on the documentation for everything fitted in Lerwick. Because building warrant and planning questions can affect the programme, we check what applies at survey and raise any approvals early rather than assuming none are needed.
Sites in and around Lerwick are covered by arrangement. There is no charge for the survey or the written quote, and any travel, ferry crossings or overnight stays needed for the installation itself are itemised in the quote, so you see the full price before agreeing.
Questions about cold store dock doors in Lerwick
Do you remove and dispose of the old equipment?
Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Lerwick, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.
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 Orkney, Shetland and the Western Isles 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.
Which building and safety rules apply to a site in Lerwick?
It depends on which UK nation the site is in. England and Wales use Building Regulations approval, Scotland uses building warrants and Northern Ireland uses building control approval from the council. Workplace safety is regulated by HSE in Great Britain and HSENI in Northern Ireland, and energy rules differ between nations. For your site in Lerwick, we check what applies at survey and design to it.
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.
Do cold store doors need more frequent servicing?
Yes, cold store doors generally benefit from more frequent servicing than ambient dock doors. Low temperatures stiffen seals, stress springs and cables, and hide early ice build-up. Checking heaters, seals and operator settings before winter is particularly worthwhile. Servicing visits are chargeable and agreed in advance.
