Thread: Garage door noise - panel vs roller door choice ?

The last house I built in Cairns had a panel lift and it was reasonably quiet. Mind you the one my parents have installed would definately wake the dead. I have found the motor units driving the doors play a big part.

In Sydney we had an electric roller door, again the unit was bloody noisy. Mind you the other units which had the same door and opener were quiet.

Since being back in Cairns I have installed some Merlin openers onto the roller doors here and they are quiet as a mouse. Mind you the ceiling has just been replaced in the garage and now the doors are noisier as they werent reinstalled by professionals.

One thing I did notice when researching which door openers to buy, particularly electric units for roller doors, 240v units are the way to go. They do not strain as hard as the 24v units. Why the step the voltage down is beyond me when they can save the heart ache and use 240v motors.

Cheers

I would hazard a guess that the installation of doors with 240 volt motors may be a bit of a concern for companies with installers having to set limit switches etc. and the installers not being qualified electricians.

Barry,
No its 100% safe, but then again Im an electronics technician, so not too scared of the green stuff. However you couldnt get a zap from setting the limit switches unless you break something. The user guide has been laid out so most home handymen can set them up.

The units I have here are Merlin units. They hang off the roller door itself. Best unit I have come across. The good thing about being 240v is that the motors do not strain when moving the door.

Having put up 100's of roller doors and control units I have found if the door is installed correctly no unit will strain to lift the door.

Installing roller doors isn't a job any handyman should be doing although I know they do it but I have had to go and fix many a door installed by a so called handyman and not only that I've had to fix doors that builders have put up and they didn't even have operators on them.

The one brand of door that I haven't installed is a Merlin. All other doors I have installed were 24volt

Just a little note to say thanks guys, there's heaps more responses and info in this thread than I'd hoped to get. Keep em coming !

Cheers,
