Wood slivers

[AronSearle]

If you are not sure about filling the smaller gaps, worth bearing in mind that a floor like this is probably fairly stable (in that the environment is stable), but a leaving a few gaps does allow for some expansion should it occur.

Some people full fill and never have any problems, so no straight answer.

There's an area near a copper pipe which will have some gaps (which I intend to cover with a 'collar' around the pipe. That'll allow for some expansion. I also considered leaving a couple of gaps where I knew the bed would be, but if you move the bed that would be a problem. Probably a horrible hacky idea!
