Have chosen engineered wood flooring to fit over my UFH. As I understand it I have 3 (or maybe 4) choices of how to fit, and am interested in views on benefits/drawbacks of each.
1) Glue direct to concrete screed.2) Fix (nail) to battens fitted into concrete.
3) Fix (nail) to joists, fitted periodically within concrete screed (perhaps every metre).4) Leave floating (on top of underlay).
In some ways, 4 seems like the best on the basis that
- it's easier
- as and when there's any shrinkage I can simply push the boards together again. However, I worry a bit about how bouncy it might be.
By the way, should I avoid engineered flooring using pine underneath the "veneer", and prefer plywood - I've seen reports that plywood is a better material to be using as there's less shrinkage (the main reason for using engineered).
Thanks, Piers
