Nice, used for soundproofing
runners in whole house, bedrooms wall-to-wall
San Jose, CA
Bought a new upstairs condo, the floors are very thin, and I have allergies so can't have carpets. Rubber is the best material for acoustic reduction, and it is frequently put underneath hard flooring.
I wanted to soundproof an existing floor so I put these tiles on top.
The regrind tiles come with edge pieces which makes them very flexible.
Because of the edge pieces it was easy to make runners throughout the house with minimal cutting, and I did wall-wall in the bedrooms for less noise while sleeping. The runners are to stop footfall noise for the neighbors below, and the wall-to-wall for a two-way sound barrier.
I kinda fell in love with the stuff so I put it under anything that moves to protect the floor.
The downside is the smell. It's been a month and the smell is slowly going away, but is not gone yet. The regrind ships with some rubber sheeting as packing material, which is another product you can buy from their site, and it's smell is going down at a similar slow rate, so I suspect it isn't the regrind per se.
The smell irritated my throat for a while, but that seems to be fading finally. I had doors and windows open a lot for a while.
On the plus side, the soundproofing helped, and the floor underneath is protected as an added bonus.
The tiles themselves are excellent quality, perfect fit, a little thicker than they say (closer to 7 and 9 mm, instead of 6 and 8).
Tin snips are your best friend for installation, as well as a box cutter and a straight edge. You can't cut all the way through in one pass with a box cutter, I just did repeated passes while holding it slightly bent and it cut easily with no effort.
The surface is a little rougher than a smooth floor, so vacuuming and mopping is slightly more effort than a smooth floor.
