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

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.
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.
Measure the headroom above the opening carefully, because insulated laths make a bigger roll than single-skin and need a deeper box.

Rules that apply in Grantham

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

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 Grantham: questions

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

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 Grantham garage so you can compare.

How long does it take to fit a roller garage door in Grantham?

Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.

Do you charge more for Grantham than other towns in Lincolnshire?

No. Guide prices are the same for Grantham as for anywhere else we cover in Lincolnshire. 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.

What do you check at a survey in NG31?

At a survey in NG31 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.

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.

Is an insulated door worth it for a detached garage?

It depends on how you use the garage. If it's only for parking or storing tools, single-skin laths may be enough. If you work out there, store anything that dislikes the cold, or want it quieter, insulated laths are worth the extra cost. Remember the walls, roof and floor also let heat out, so the door is only part of the picture.
