Insulated sectional garage doors in County Antrim
Looking for an insulated sectional door in County Antrim? We cover Belfast, Lisburn, Newtownabbey and Carrickfergus and the rest of the area, measuring, supplying and fitting each 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 County Antrim?
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.
Will an insulated door help an integral garage?
Where a garage shares walls with the house, a colder garage means colder shared walls and rooms above. An insulated door will not turn a garage into a habitable room, but it does take the edge off, especially paired with a draught-sealed door between the house and the garage.
Which options can you choose?
- 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.
- Window insertsAdd glazed inserts for daylight; they slightly reduce thermal performance.
- Seals all roundBottom, side and head seals, plus gaskets between sections.

Our free survey checks the opening, headroom above it, room either side for the tracks, garage depth and where an operator will be powered from.
What rules apply in County Antrim?
In Northern Ireland, fitting a new door within an existing opening generally does not need planning permission. If the property is listed, in a conservation area or covered by an Article 4 direction, check with your council planning office before ordering, as consent may be needed for changes to the outside of the building.
Planning authorities in County Antrim include Antrim and Newtownabbey Borough Council, Belfast City Council, Lisburn and Castlereagh City Council and Mid and East Antrim Borough Council.
Under the Windsor Framework, products placed on the market in Northern Ireland follow EU rules, so doors carry CE marking (with UKNI where a UK body assessed them). UKCA marking on its own is not accepted in Northern Ireland.

Questions about insulated sectional garage doors in County Antrim
Can an insulated door be fitted to an older garage?
Usually, yes. The opening needs to be sound and square enough to fix to, with enough headroom above the opening and room either side for the tracks. The survey checks all three.
Is an insulated garage door worth it?
If the garage is integral, heated, used as a workspace or stores anything sensitive to cold and damp, yes. For a detached garage used only for parking, a standard double-skin door is often enough.
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.
Which towns in County Antrim do you cover?
We cover Belfast, Lisburn, Newtownabbey, Carrickfergus, Ballymena, Antrim and Larne and other towns across County Antrim.
Do I need planning permission in County Antrim?
Usually not when the door goes into the existing opening. In Northern Ireland, check first if the property is listed or in a conservation area. Check with your local planning authority if in doubt.
