| I installed and serviced residential and commercial garage doors for three years, about a decade ago. I never serviced or installed a one piece tilting garage door, but I replaced a couple with sectional overhead doors. All residential doors I installed were sectional, and most commercial as well, but some commercial doors were rolling steel doors. From what I've seen, most of the one piece tilting garage doors are a thing of the past. Inconvenient and somewhat dangerous when a spring breaks.
The solid wood panel sectional doors on higher end houses are more expensive and look nice, but I'll take an insulated steel door anyday. An insulated steel door like the 16' x 11' door I have on my shop can have an R (insulation) value of up to about 13 or 15 vs most wood doors that only have R values of 1-3.
