Insulated sectional garage doors in West Sussex
We supply and fit insulated sectional doors across West Sussex, including Crawley, Worthing, Bognor Regis and Littlehampton, with a free survey and a fixed written price for every door.
An insulated sectional garage door is built from horizontal steel panels with a foam core bonded between two skins, usually 40 to 42 mm thick, or around 67 mm on thermally broken doors. The panels hinge as they rise, run up vertical tracks and park flat under the ceiling, so the door keeps heat in, cuts noise and never swings out onto the drive.

What should you know about insulated sectional doors in West Sussex?
Is it worth it on a detached garage?
On a detached garage used only for a car, a standard double-skin door is usually enough. If you keep tools, bikes, a freezer or stock in there, or you use it as a workspace, the warmer, drier conditions are worth the extra cost.
What thickness should you pick?
Most domestic sectional doors use panels of about 40 to 42 mm. Doors sold as thermally broken use thicker panels, often around 67 mm, with a break between the inner and outer skins so cold is not conducted straight through. The thicker option costs more and needs a little more headroom, so it makes most sense on integral or heated garages.
Do insulated doors weigh more?
Yes. Foam-filled steel panels are heavier than single-skin doors, which is why every sectional door is balanced by springs sized to that door, either torsion springs on a shaft above the opening or tension springs along the tracks, depending on the range and size. They are set during fitting so the door feels light by hand and the motor is not straining.
Which options can you choose?
- Window insertsAdd glazed inserts for daylight; they slightly reduce thermal performance.
- Panel thicknessTypically 40 to 42 mm double-skin, or thicker thermally broken panels on premium ranges.
- Electric or manualMost insulated doors are motorised; manual operation is possible on lighter doors.
- Any finishRibbed, flush, cassette, woodgrain and coloured finishes are all available with insulated panels.
- Seals all roundBottom, side and head seals, plus gaskets between sections.
How much does an insulated sectional door cost in West Sussex?
Guide price: £2,095–£3,495 inc VAT. That covers the door, fitting, removal of a standard old door and VAT; the fixed price follows the free survey.
The survey is free and there is no obligation. We measure width, height, headroom, side room and depth, and look at power for an operator.
What rules apply in West Sussex?
In England, swapping a garage door for a new one, including an electric sectional door, does not normally need planning permission. Permission or consent can be needed if the house is listed, if it sits in a conservation area or is covered by an Article 4 direction, or if the new door would noticeably change how the house looks from the street. On many newer estates a planning condition removes permitted development rights or requires the garage to be kept for parking, so check your planning history before changing the door or the use of the garage.
Planning in West Sussex is handled by the district and borough councils, not the county council.

Questions about insulated sectional garage doors in West Sussex
Can I add insulation to my existing up-and-over door?
Insulation kits exist for up-and-over doors, but they add weight that the springs were not designed for and seldom seal well. Replacing with an insulated sectional door is the reliable route.
What U-value will I get?
Manufacturers publish U-values for each range and size. As an example, one leading range quotes about 1.4 W/m²K for a fitted 42 mm door and about 1.0 W/m²K for its 67 mm thermally broken version, against roughly 6.5 W/m²K for a single-skin steel door of the same size. Window inserts reduce performance slightly. We give you the published figure for the exact door on your quote.
How much does an insulated sectional garage door cost?
Guide prices for a single insulated sectional door supplied and fitted with an electric operator run £2,095–£3,495, from a standard door up to thermally broken panels. Size, finish, glazing and the state of the opening all move the figure, so we confirm a fixed price after a free survey.

Do I need planning permission in West Sussex?
Usually not. Replacing a garage door, including with an electric sectional door, does not normally need planning permission in England unless the house is listed, in a conservation area or Article 4 area, or has planning conditions affecting the garage. Check with your local planning authority if in doubt.
