Plate Installation

You want as even of spacing between the plates as possible. If you butted against the joist you would have to wide a gap between the two and the next plate would be to close.

I don't know about your area but in my area someof these homes don't really have "uniform spacing" :)

Plate Installation

Can you butt the aluminum plates of a radiant staple -up installation along the joist or should there be a bit of floor space between the edge of the plates and joist. i.e. expansion etc.
Thanks

Scott, I am keeping an even spacing where it permits, but there are a number of joist spaces that are narrower than most. Butting up against the joist in these cases will give me a more even spacing. I was only concerned if there was an expansion issue to consider with the plate up against the joist.
Thanks

As long

as you are a 1/4" off the joist, I don't think you'll get noise but it would be a concern.

I see

no reason. You're already tightly attaching the plates to the plywood, so the wood of the joist shouldn't be any different.

Thanks for your replies. I think keeping a small distance between the joist and plate will be the way to go.
