Heavy, insulated garage doors are then needed, so I guess heated garages are in part enabled by electric door openers. The weight of a garage door shouldn't matter if its lifting springs are properly chosen and adjusted. Those springs should balance the weight of the door no matter how heavy it is. I suppose that's approximately true, but adjustment gets fiddly if you need to balance to within a small fraction of the weight, and the springs get bigger and scarier. I have replaced the springs on my manually operated garage door, after one of them broke during the night and went flying. I adjusted the springs until it was reasonably easy to open the door, and then stopped. I installed our electric opener in our old garage, and helped another family member install another. The instructions made it very clear that the opener was not designed to heft the weight of the door on its own, and that proper spring balance was necessary. Older garages tend to be detached, and unheated, like mine. And like mine. BTW, one aesthetic aspect of modern McMansions that I dislike is the huge front-facing garage door. It's even worse when the garage door sits several feet forward of the front door and porch. It's like the house is actually designed for the automobile, and humans are grudgingly allowed to live there. Agreed. Sometimes the garage door is the most prominent architectural feature seen from the street. I would not want to live in such a house. |

I adjusted the springs until it was reasonably easy to open the door, and then stopped. I agree it's scary. I've adjusted several garage doors with torsion springs. Most involved standing on a ladder and using 1/2" x 2 foot long steel bars to apply torque to the spring collar, then tighten down a set screw to hold it. There's some serious energy stored there, and it's a scary process. OTOH, the door that I mentioned being replaced had a nifty gear driven adjustment scheme for the torsion springs. Spinning a hex head driver torqued the spring, easy as pie. I'm sure it was much more expensive, but it was SO much less scary! -- - Frank Krygowski |
