So I want to install an attic vent fan in my house (1600 s.f.). I bought one for $88. I've done this in my old house, but didn't like the noise transmitted to the frame. I could hear it in the house.
So this time I want to mount it with rubber washers. I thought, well, Sorbothane should work great! Um, $30 worth of rubber washers to mount an $88 fan:
Amazon.com: Isolate It: Sorbothane Vibration Isolation Washer 30 Duro (0.5" ID - 1.5" OD - 0.5" Thick) - 4 Pack: Home Improvement

Would regular rubber work as well?
Does anyone know a cheaper source of Sorbothane washers?
Why are they so pricey anyway? Active patent?

I've used these at work with positive results. Not much cheaper i guess...
McMaster-Carr
McMaster has a pretty big selection of vibration reducing washers. I've also used specialty rubber isolators that you cut dow to your own desired thickness. But now i can't find it. Maybe i bought it off ebay.
Edit* This fan has 8 mounting points?
