Hi - I'm posting some questions about the best way to get the perfect floor.
My wife and I have chosen to have Teragren Synergy (strand) bamboo installed in the first and second floor in our N.Va. home. I would love to hear to from this experienced community on what we are planning and any tips or advice.
***Background:
-We chose the floor because I want a warhorse of a floor that will last and last and last. Strand bamboo is tough, teragren is supposed to be the best. Consumer Reports rated highly.
-I have installed ~100 sq. ft. nailed down in our closet as a test run for the product. (I'm handy, experienced DIYer). We like the color, and it didn't flinch when hit with a hammer (by accident. Several times). Product quality seemed excellent. Did bang up a few tongues with the cleat nailer (18ga) and the brad nailer did not work at all - I had one brad u-turn and come back out the top. Pre-drilled and finish nailed starter row. Glued last 3 rows.
***Tech Specs:
Teragren synergy strand bamboo MPL tongue and groove (1/2", solid)
~2000 sqt ft, 1st (about climate controlled basement) and 2nd floor.
includes:Stairs with solid tread (both contractors said glue them)
includes: a sunroom (1st floor, over basement)
3/4" T&G plywood subfloor
Northern Virginia
Will have teragren authorized dealer install
One dealer would much prefer glue down - says face nailing is ugly and will not fill with putty right
***Questions
What is the general opinion of nailing (over asphalt impregnated kraft paper) and are there any problems I might expect?
What's the opinion on durability and potential problems of a glue down install - either on luan (for flatness) or over FloorMuffler or 1/4" cork? I'm really not familiar with glue down at all
In your house, would you glue or nail?
In your house, would you glue over cork or FloorMuffler-type product? 2nd floor only or 1st as well?
What are your thoughts and experience on doing the sunroom?
Does this community hold an opinion on the Teragren strand products?
***Thanks to anyone who has taken the time to read or share knowledge. Much appreciated

You may want to call Terragren first. I pretty sure that some of the synergy line is GLUE DOWN ONLY. At one time they allowed both nail and glue but as the instability of strand woven bamboo has become more apparent plus the difficulty in nailing strand woven they have nixed the nail down option. Float or glue only.

Terragren is one of the best. But like Kevin said, strand is a touchy animal. We're constantly discovering more and more about the performance, inability to moisture check it, it's lengthy acclimation period etc etc.
Your installer better be on his game with this stuff. It's not at all like just installing a closet because the problems can multiply significantly with larger rooms and different zones of the country.
