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

Wider openings usually suit 77 mm laths for rigidity, so expect the lath size to be confirmed once the width has been measured at survey.
Check whether the floor dips or rises across the opening, because an uneven floor can leave a gap under the bottom rail that lets draughts in.
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.

Rules that apply in England

Planning

Replacing a garage door is not usually development that needs planning permission. Check first if your home is listed (listed building consent covers works that affect its character), sits in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.

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.

Questions about insulated roller garage doors in Cornwall

Are guide prices the same across Cornwall?

Yes. The guide prices are the same in every town in Cornwall. The written quote reflects your opening and the door you choose, not your postcode.

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

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.

How do I book a survey in Cornwall?

Start with the guide price tool or the form on this page. We then contact you to arrange a free survey for a new door, replacement or conversion, and confirm the date in writing.

Are insulated roller doors available in different colours?

Yes. Insulated doors come in the manufacturer's standard range finishes, and you can choose a RAL colour or a woodgrain effect as a priced extra. Colours outside the manufacturer's range are priced on survey. If you're matching windows or a front door, have the RAL code to hand when you ask for a guide price.

Can insulation be added to my existing roller door?

Not in a practical way. The foam sits between the two aluminium skins of each lath when it's made, so a single-skin curtain can't simply be filled or lined. Getting insulated laths means a new curtain, and because the box and barrel need to suit the larger roll, that normally means a new door, which we can quote as a replacement.
