Hi Mike, thanks for the suggestions.

We are really trying to have the reciprocating timbers visible, both from above and below. It would be a shame to go to all the trouble of making this floor and then covering it up with decking.

While we will be sound deadening and covering the ceiling in parts of the house, in other parts, we want the floor decking visible, to give an enhanced feeling of space.

I really don't want to cut a bunch of holes in the timbers though, so, maybe, it is just a small boxed out chase running around the perimeter of the house. I have the headroom for it, and we can make it look a little sexier than just a box.

I wish they had Cadet chiller units as well as heaters; that would be handy.

Cheers, Chuck
