I always use a T-mold when a toilet is locked down on any floating flooring. When a row is locked in somewhere and adjacent ones are not then thats when you get end joint separation. Seen it many times.
By the way, I called US Floors and asked about separating the bathroom with a T molding.
Customer wants the new cabinets installed on top of the Coretec. Cabinet footprint is tiny. The refrigerator and stove will hold down the Coretec with 4 times the force/weight of the cabinets.
I asked the US Floors guy about that. He said
only if I glued it.
...so then I told him the bathroom was way down a hall, a good 35 feet from the kitchen. He said they don't recommend the molding because the material is stable.
.......so I said, "if that's so, maybe I should leave a 1/4 inch gap at the tub and fill the gap with silicone"
...he says "you could fit it closer than that and just caulk against the tub"
sooooooooo, ....a 35 foot + run from the kitchen to the bathtub is fine and I can pretty much butt to the tub, and that's all peachy keen.
.....however
two small cabinets in the kitchen
and screwed only to the wall, is a no no.
The rules on this material confuses me.
I think they just make stuff up.
