What should Portslade 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.
Which options are available in Portslade?
- 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.

Questions from Portslade customers
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.
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.
Do you cover Portslade?
Yes. We cover Portslade, including postcode districts BN3, BN41. 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 Portslade?
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. If in doubt, check with Brighton & Hove City Council.
Do you also cover towns near Portslade?
Yes. Close to Portslade we also cover Hove (2 mi), Brighton (3 mi), Peacehaven (10 mi) and Lewes (10 mi).
