Warehouse doors

Prices checked November 2026 · before VAT

Most warehouses need three or four kinds of door: insulated sectional doors on the loading docks, a roller shutter or two on drive-in openings, fast doors on busy internal openings, and fire shutters wherever an opening breaks a compartment wall. Below, each opening is drawn to the same scale with the door that usually suits it.

Four questions that decide the door

How often does it open?

A door that opens ten times a day and one that opens three hundred times are different machines. Count or estimate the cycles, and tell the surveyor; it decides the operator, the springs and sometimes the door type.

Is the building heated or chilled?

On a heated or temperature-controlled building, the door is a large hole in the insulation. Insulated sectional doors, dock shelters and seals, and fast internal doors all reduce the loss. On an unheated store none of that is worth paying for.

How much space is there above and behind the opening?

Sectional doors need headroom and a clear run back under the roof; roller shutters need a box over the opening; high-speed doors need a compact head and room for side frames. Racking, cranes, sprinkler pipes and lighting often decide this before price does.

What has to happen at night?

If the opening must be secure out of hours, it needs a steel shutter or a sectional door, not a fabric door on its own. Insurers often have a view on this, so check the policy before choosing.

Warehouse door questions

What is the best door for a warehouse?

For loading docks on a heated warehouse, insulated sectional doors with levellers and shelters. For drive-in openings, unheated buildings or tight headroom, roller shutters. For busy internal openings, high-speed doors. Most warehouses end up with a mix.

How much do warehouse doors cost?

Before VAT, for one door: an insulated sectional dock door £2,400 to £4,100, an insulated 4 x 5 m roller shutter £4,300 to £8,200, a fabric high-speed door £7,600 to £15,300. See the industrial door cost calculator.

What size are warehouse loading doors?

Dock doors are commonly about 3 m wide and 3 to 3.5 m high, sized for the rear of a standard trailer with the leveller at about 1.2 m dock height. Drive-in doors for lorries are typically 4 to 5 m wide and 5 m or more high.

Do warehouse doors need to be insulated?

On a heated warehouse, yes in practice, and on new buildings in England the doors must meet the energy rules: Approved Document L sets a limiting U-value of 1.3 W/m²K for vehicle access doors. Unheated stores can use single-skin shutters.

Should a warehouse have a separate pedestrian door?

Yes where possible. People and forklifts sharing a vehicle door is a known risk. A separate personnel door next to the vehicle door, or at least a wicket door, keeps pedestrians out of the vehicle route.
