Post Subject: Joe is flooredPosted by Gargoyle on: 8/1/2024
I've come across this video a few times lately, perhaps since Gutterberg has made the algorithm.
Joe is quite proud of the extra plywood that he put on the walls and floors. A noble cause for the backdrop given he is on a highway, however I question the merit of stiffening of the floor, then adding pliable glue on top. It bothers me as an approach of pinning diarrhea to the wall, seeing what sticks.
IMO quite often it's the first surface that is the most important. Joe has a Cherry wood floor. Does it matter if he attempted to decouple it with soft glue? I am about 90% sure that floor is still nailed down in addition to the glue.
The floor is a resonant acoustic panel. Is it wise to add more tension and a stiffer propagation surface? If you're making an acoustic guitar these would be notable features.
A "silent" floor in the home construction sense means it doesn't crick and crack when you walk on it. It does not mean it is quieter, they are louder overall.
Similar to adding Roxull insulation to wall and floors to "sound proof" rooms. It works great until you put drywall on it. The sound goes through the studs, circumventing the insulation for the most part. Definitely negligible effect.
Modern spray foams on the other hand do seem to both tighten and simultaneously dampen a structure. You can feel a house that has been spray foamed.
The foam is heavy, yet not hard. One of the most remarkable and always overlooked feature of these foams is how they glue together a house on the macro scale.
Given the date of Joe's renovation, it is unlikely that Joe had his walls sprayed, perhaps he just filled the window gaps with canned foam.
