What should I know about insulated roller garage doors in County Londonderry?

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.
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.
If the garage is integral, consider how much cold air and noise currently reaches the rooms that share a wall or ceiling with it.
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.

Rules that apply in Northern Ireland

Planning

Replacing a garage door is not usually development that needs planning permission in Northern Ireland. Listed building consent applies to listed buildings, and conservation-area controls, planning conditions or covenants can restrict changes to how a garage looks, so check before ordering.

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 CE marking, which is the marking that applies to machinery placed on the market in Northern Ireland.

Questions about insulated roller garage doors in County Londonderry

Which towns do you cover in County Londonderry?

We cover County Londonderry, including Derry/Londonderry, Coleraine, Limavady and Magherafelt. Every town has its own page with local details, and you can start a guide price for any postcode in County Londonderry online.

Are guide prices the same across County Londonderry?

Yes. The guide prices are the same in every town in County Londonderry. 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 County Londonderry?

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

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.

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.
