Garage door - retractable vs sectional?

Lemoncurd

We're planning on getting a new garage door and plan to automate it.

Does anyone have any thoughts on the advantages/disadvantages to having a sectional vs retractable (up and over) one?

Currently we have a retractable door in a timber frame. The frame has started to deteriorate so needs replacing too.

I've had a few quotes and the first guy to come out seemed keen to sell us a sectional door from the word go. I said no because we do not want to lose any length from the garage (they are usually fitted behind the garage opening). After looking a bit more he said that the sectional door would be more cost effective because it would have it's own frame so we wouldn't need a new frame.

He then quoted for a sectional door fitted IN the door opening rather than behind it. Has anyone done/got this? all the manufacturer literature and everything else I've seen/been told says that they need to be fitted behind the opening.
He declined to quote for a new retractable door saying that it would be a lot more expensive for a door that wasn't as good, although was prepared to replace our door frame and put the old door back in.

Another company (which doesn't supply or fit sectional doors) has quoted for replacing the frame and door but it comes to £300 more than the sectional door.

OH is now keen to go for a sectional door but I'm a bit concerned about it being fitted in an unconventional way - would we get a poor finish/security etc? Are they really better?

Any reason why you haven't looked at a roller door? There are some very good insulated and prefinished doors available which are available automated they should tend to be cheaper than sectional. The benefit of sectional or roller type doors over canopy type doors are basically that you can drive right up to them which is ideal where space is limited.
