Related question: HE Front End Washer vibrations on wood floors: any tried-and-true solutions?
In hopes of being able to keep our new front-end HE washer (which we like) I've decided to bite the bullet and reinforce the floor underneath.
- add blocking between joists underneath (crawl space access)
- glue+screw subfloor to joists
- glue+screw additional layer of plywood to subfloor to stiffen everything.
Would adding a layer of cork underlayment between the subfloor and additional layer of plywood be of any benefit (or detriment?)
The theory is that it might add a bit of decoupling between layers to reduce vibration migration into the framing.
Does my theory hold any water?
BTW, we're thinking of putting tile on the floor when finished. Figuring that it may also add another level of 'stiffening' to the floor sandwich (using larger 1x2' tiles)
