What should Cardiff homeowners know about insulated sectional doors?
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.
Options and upgrades for Cardiff homes
- Panel thicknessTypically 40 to 42 mm double-skin, or thicker thermally broken panels on premium ranges.
- Window insertsAdd glazed inserts for daylight; they slightly reduce thermal performance.
- 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.

Questions from Cardiff customers
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.
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.
Do you cover Cardiff?
Yes. We cover Cardiff, including postcode districts CF5, CF10, CF11, CF14, CF23, CF24. Installation and visit dates depend on installer availability and are agreed when you book.
Do I need planning permission for a new garage door in Cardiff?
Usually not. A replacement garage door of similar appearance is normally minor work in Wales, but listed buildings, conservation areas and planning conditions can change that. If in doubt, check with Cardiff Council.
