An inflatable dock shelter is a dock shelter with air-filled fabric cushions at the top and sides of the opening, kept deflated and close to the building until a trailer has reversed in. A fan then inflates the cushions so they press against the trailer roof and sides, giving a close seal that adapts to different trailer widths and heights, and deflates again before the trailer leaves.
What matters for inflatable dock shelters in Gwynedd?
Fresh produce cooled at a packhouse in Gwynedd stays colder during loading when the gap around the trailer is sealed by inflated cushions. Pharmaceutical distributors around Gwynedd working to tight temperature limits may want the close seal an inflatable shelter gives during every load.
Frozen food stores in Gwynedd loading trailers of varying sizes can use inflatable shelters to keep warm outside air away from the open door.
A single contact at Loading Bay Doors handles your project in Gwynedd from start to finish. The free site survey and fixed written quote come first, with no obligation to proceed. We then book the installation for times that suit the operation, including out of hours by arrangement, and manage the specialist engineers on site. At the end we commission and test the equipment, walk your team through it and provide the documentation.
What is involved in installing an inflatable dock shelter?
Installing an inflatable shelter involves fixing a steel frame to the building around the dock door, mounting the cushions and fan, and wiring the controls, usually over one to two days per bay.
- The wall is checked and fixing points or a subframe prepared.
- The frame is fixed from powered access equipment in the yard.
- Top and side cushions are fitted, with protective covers where specified.
- The fan unit is mounted and the control panel wired, including interlocks to the door, leveller or restraint.
- Inflation, deflation and cushion retraction are tested with a trailer in the bay.
You will need to provide a clear yard area in front of the bay, take the bay out of use and arrange a power supply near the door, or ask us to include one. At cold stores we plan the work with the dock door kept closed, so the store stays at temperature while the shelter goes up outside.
Inflatable shelter, curtain shelter or dock seal: which suits a cold chain dock?
For a cold chain dock that receives trailers of different sizes, an inflatable shelter usually gives the best balance of close sealing and flexibility. A dock seal can match it on a uniform fleet, while a curtain shelter is better suited to ambient bays.
- Inflatable shelter: cushions adapt to each trailer's width and height and seal close to the body, with the full opening left clear.
- Dock seal: a tight, lower-cost seal when every trailer is the same size, but it can leave gaps on other vehicles and the pads can intrude into the opening.
- Curtain shelter: flexible and robust, but leaves small gaps that matter more at chilled and frozen docks.
Inflatables also stand clear of the trailer until it has docked, avoiding the rubbing that wears foam pads and curtains. The trade-off is the fan and controls, which need power and servicing. For frozen docks we specify the shelter alongside cold store dock doors so the two work together.

Regulations and approvals in Wales
HSE regulates workplace safety in Wales. Loading bays in Gwynedd need doors that meet regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, work equipment maintained under PUWER, and safeguards that stop vehicles leaving the dock too early. We check what applies at survey and build those measures into the design.
Questions
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Gwynedd site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
Will you deal with building control and planning for a project in Gwynedd?
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.
Can a punctured cushion be repaired?
Small punctures and tears can usually be patched, and a badly damaged cushion can be replaced on its own without changing the frame or fan. Repairs are carried out on a chargeable visit, with the price agreed before anyone attends.
What happens to an inflatable shelter if the power fails?
If the power fails, the fan stops and the cushions gradually deflate, so the trailer can leave once loading has been brought to a safe end. At a cold store, the dock door should be closed by hand where possible to protect the store. We explain the power failure routine at handover.
