Gaps and thresholds between hall and rooms?

[alba2]

Question 1. I am about to lay an engineered oak floor. I have read some manufacturer's instructions where it says that gaps and thresholds should be used between rooms.
However, I would like an uninterrupted run between lounge and hall as well as hall and bedroom. When I thumb through the various manufacturer's wood brochures the photos show no thresholds between rooms and hall.
Is it essential to have them? Am I risking creaking if I don't?

Question 2. It is a new build. Should I go over all the chipboard floors and check that there is not even a slight movement and screw down where there is?
I ask this because I have read that due to drying out over time chipboard floors will move and slacken over time anyway, so it is wasted effort.

I have read yet another web page which says that a 10-15mm gap must be left between rooms and hall. I am too nervous not to leave a gap in case of creaking etc problems.

Any comments on this?

What do your mfr's inst's say?

Sometimes, depending on the flooring and the layout the floor can flow thro from room to room. At other times it must stop at the threshold, and use a hardwood threshold bar (probably a T-bar).

Whatever, the jambs and architraves must be undercut, and edge spacing dimensions observed.

Really, its a professional site call for what you are asking.
