What should I know about insulated roller garage doors in Penzance?

Check whether the garage has other weak spots, such as a single-glazed window or a gappy side door, that will still let heat out after the new door goes in.
Look for a socket or fused spur near the top of the opening, as every insulated door in our price list is electric.
Measure the headroom above the opening carefully, because insulated laths make a bigger roll than single-skin and need a deeper box.
Decide whether you want extras such as battery backup or a wireless keypad, so they can be included in the written quote rather than added later.

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Structural work

Widening the opening, removing a central pier or fitting a new lintel is structural work that needs Building Regulations approval from building control before it starts.

Insulated roller garage doors in Penzance: questions

Do you cover Penzance?

Yes. Penzance is part of the area we cover in Cornwall, including TR18 and TR20. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you charge more for Penzance than other towns in Cornwall?

No. Guide prices are the same for Penzance as for anywhere else we cover in Cornwall. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

Do I need permission for a new roller garage door in Penzance?

Replacing a garage door is not usually development that needs planning permission in England, and widening the opening needs building control approval. If you live in a listed building, a conservation area or on an estate with covenants or planning conditions, check before ordering.

Is an electric roller door worth it for a garage in Penzance?

That depends on how often you use the garage. An electric door opens from the car with a remote and has safety devices fitted, while a manual door costs less and suits occasional use. We price both for your Penzance garage so you can compare.

Is an insulated door more secure than a single-skin one?

Not automatically. Insulation and burglary resistance are separate qualities. How well a door resists attack depends on how that specific manufacturer's model has been tested, for example to LPS 1175 or STS 202. If security is a priority, look at our security-rated doors, which are also insulated, and we'll show you the certificate for the exact model.

Will an insulated door fit the same opening as my old single-skin door?

Usually, yes, but insulated laths are thicker, so the curtain makes a bigger roll in the box. If your old door had a small box, the new one may need more headroom, a box fitted under the lintel, or a face-fitted box. We check this at survey and explain the trade-offs before you choose.
