I am trying to decide whether I should install a floated bamboo floor or
nailed bamboo floor in my house. I understand that the floated floor is
easier to install but more expensive because of extra materials. The reason
for considering a floated floor is the mother-in-law apartment that is
below....though I have not rented it out but may in the future. The floated
floor may provide better sound transmission blocking.

On the other hand I like the idea of nailing to floor to solidly lock it
down in. I don't like the springiness that I may get with a floated floor.
I can use cheaper solid wood bamboo or the more espensive engineered bamboo
floor. With the floated floor I have to use the engineered product.

Any advice would be appreciated.

BTW, I will be installing this floor myself so installation tips are also
appreciated.

Thanks!
David

Hi,

In my opinion, floating floors are used mainly so that a floor can be
laid over tile, concrete, etc. If you don't want to raise the floor
another 3/4" by installing plywood, then float the floor. If the
substrate isn't an issue and you're looking for sound blocking
properties, there are much better ways to go than floating the floor.
If I read your post right, it's your own home your talking about. Put
in the extra day or so of work nailing in the floor and enjoy a
lifetime of a structurally sound flooring. As far as using engineered
vs. solid, bamboo is much more stable than oak. If you're installing
at or above grade level on plywood, save your money and go with
solid. If you have no choice but to float over concrete, go with
engineered. In NYC, you can buy solid bamboo flooring for about
$2.00 / SF at Costco - they beat all the flooring distributors on
that. Not sure where you're from or what pricing is like elsewhere.
Good luck to you.

Aother thing I forgot to mention - install tips. Let the floor
acclimate in the room to be installed for at least a few days before
installing. Leave an expansion gap at the walls running parallel to
the boards (to be covered later with molding). Use a white mallot for
prefinished floors - not black. Don't be shy with the nails and make
sure you can buy any necessary transition pieces to match the floor
before you buy.
