Casa,
I think laying the silkwood floor before kitchen installation wouldn't be a good idea because it is pre-finished.
We laid our solid timber floor before kitchen was installed & the floor was sanded & a sealer put on.
After all trades had finished coming in the house, the floor then had another light sand & 2 more coats of finish applied.
I think you would be stressing the whole time your house was being completed wondering if your floor was going to be damaged with the silkwood.
What is you reason for not wanted solid timber?
