Have you considered the amount of headroom space required for fitting a sectional garage door? This all depends on if you plan on automating the garage door. Automatic garage door openers are fitted against the the ceiling of the garage; this requires additional room between the ceiling and the top of the garage door opening. With all the benefits offered by an automatic garage door, it’s still worth considering automating your garage door as an option. Today’s garage doors are designed and manufactured to maximize space for efficiency. Manual sectional garage doors require as little as 70mm of headroom space; whereas, electric garage doors require double the amount of room (140mm).
