Insulated sectional garage doors: what matters for Llanelli garages
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.
How much difference do seals make?
Panels are only half the story. A good door has a flexible bottom seal that follows uneven floors, brush or rubber side seals, a head seal and finger-safe joints with gaskets between sections. A badly sealed insulated door can lose more heat round the edges than through the panels, so seals are checked and set on fitting day.
What can you choose for your Llanelli garage?
- 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.
- Panel thicknessTypically 40 to 42 mm double-skin, or thicker thermally broken panels on premium ranges.

Questions from Llanelli customers
Do insulated doors need more headroom?
Thicker panels can need slightly more headroom. Where space is tight, a low-headroom track or a side-sectional door may suit better.
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 for a new garage door in Llanelli?
