Wood ceiling vibrating from a fan
« on: July 16, 2014, 08:08:51 PM »
Every room in the house has a ceiling fan my husband installed.  They all are working just fine.  Except one room, the bedroom.  We have a beautiful wooden ceiling, slats.  The fan vibrates the wood and it's so annoying we don't use the fan.  Plus it vibrates to the bedroom above it.
 Hubby tried putting some pieces of rubber in the small space between the fan and the wood, but it didn't help.   So we can't use the fan at all.      Help.

As long as the fan and outlet box are hard mounted to the blocking or joist you will not be able to stop the vibration. First rule in soundproofing is to "decouple from the structure or vibrating surfaces".

And the all wood ceiling doesn't help it actually adds to the speed of vibration over standard drywall.

Using the rubber didn't help because the vibration is going through the screws back into the structure.


I wish there was an easy solution but we can not beat the physics.

Thanks, for your answer.  What if we took the fan down and replaced it with one that didn't touch the ceiling at all?  Do they make them like that?     Or would it not matter because of the wooden ceiling?
 I. Would hate to go buy another one, have the hubby replace it, only to find that it doesn't make a difference.

They do not make a ceiling fan like that.. by code the electrical box must support 70lbs and has to be hard mounting in the ceiling to a joist or wood blocking between joist.

putting up a replacement will most likely change nothing!

I know it is not the news you want to hear but better than wasting hard earned money on attempts that will not work.

Best bet, get a floor fan.

Thanks Randy.  I certainly don't want to go through all the time and hard work of a replacement to find out it won't work............I thank you and so does the hubby.
