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.
Why do sites in Harpenden choose this?
Pharmaceutical distributors around Harpenden working to tight temperature limits may want the close seal an inflatable shelter gives during every load. Operators replacing foam seals in Harpenden that keep wearing out against ill-fitting trailers may find an inflatable shelter suffers far less rubbing.
When a chilled dock in Harpenden sees condensation and ice around the door, the seal at the trailer is often where improvement starts.
Your loading bay stays our responsibility from the survey to the handover. In Harpenden, the survey and written quote are free, and the quoted price is fixed for the agreed scope. Installation is carried out by specialist engineers working under our management, at times planned with you to protect your loading schedule. Out-of-hours work is available by arrangement. We finish by testing the equipment and handing over its documentation.
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.
How does an inflatable shelter work with the dock door and leveller?
An inflatable shelter is the first step in the dock sequence: it seals around the trailer before the door opens and only deflates once the door has closed. Getting that order right is what makes it effective.
- The trailer reverses onto the bumpers, guided by dock lights and wheel guides.
- The trailer is secured by restraint or key control, and the outside light shows red.
- The cushions inflate around the top and sides of the trailer.
- With the trailer sealed, the door opens and the leveller is deployed.
- After loading, the leveller is stored and the door closed.
- The cushions deflate and retract, and the light turns green.
Deflated cushions must sit clear of the door and leveller, and internal straps or weights pull them back so trailers do not catch them. Interlocks make each step depend on the last, so staff cannot open the door onto an unsealed trailer.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.

- Escape routes and pedestrian doors close to the bay
- Temperature requirements for chilled, frozen or ambient goods
- Yard gradient and the slope of the approach to the dock
- Traffic routes for vehicles and separation of pedestrians
- Condition of any existing leveller pit, kerb angles and pit drainage
Options to discuss
Three-sided inflatable
Top and side cushions that inflate around the trailer for the closest seal, the usual choice for chilled and frozen docks with mixed trailers.
Protective outer covers
Hard-wearing covers over the cushions that shield the fabric from weather, sunlight and trailer contact, extending cushion life on exposed docks.
Planning, building control and safety law in England
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Harpenden. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions about inflatable dock shelters in Harpenden
Will you deal with building control and planning for a project in Harpenden?
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 the site survey in Harpenden 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.
Can you work outside our normal operating hours in Harpenden?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
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.
