I’ve a 20’ double garage, previously fitted with two 7’ up n overs. About 5 years ago, myself and a builder pal knocked out the central supporting pillar, put in a long overhead steel, and replaced with a 15’ ( possibly longer) insulated sectional door.
The old metal up n overs let in cold draughts, leaves, mices etc
The new sectional has a deep rubber rand on the bottom preventing this....in your case maybe a roller rather than sectional is ok, but on wider doors the roller variety tend to rattle, a lot, in high winds as they don’t have the rigidity of an insulated sectional door. This eventually leads to a failure according to lots of reviews I read.
Obviously roller shutter doors on industrial buildings are more sturdy
I should have replaced the 7’ twins 20 years ago !
