Key questions about insulated sectional doors in Letchworth Garden City
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.
What can you choose for your Letchworth Garden City garage?
- 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.
- Seals all roundBottom, side and head seals, plus gaskets between sections.

Questions from Letchworth Garden City 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.
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.

Yes. We cover Letchworth Garden City, including postcode districts SG5, SG6, SG7. Installation and visit dates depend on installer availability and are agreed when you book.
Will the local district or borough council need to approve my new garage door?
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, ask the local district or borough council before ordering.
