Cobblewood floor

Saw a floor like that on one of the TV shows, but he used 4” branches. 3cm thick should suffice. I’d glue them in place (I think the maker used grout on his) and then hit the whole floor with one of those new “Orbital” floor sanders. Then polyurethane.

The one on TV was truely unique looking…I think it was the “Extreme Homes” show.

What you are trying to do sounds similar to the project posted by Thomas Porter. He posted an end grain floor project and blog that went through the various steps necessary to complete the project. You may want to send him a private message asking for advice.

Hope this helps.

Yes i saw (and admire) but using dry dimensioned wood that can be cut on a table saw is a lot simpler (no drying, checking, planing or “grouting” for instance). But interesting nevertheless.

PJ are you indending on using green timber if so i would stick dry it before laying it this is a time comsuming project but i think you and everyone else would love the end result

good luck and i hope you will show us all the end result

When you mention hydronic floor, do you mean a concrete floor with infloor heating?

-- ....next big purchase is wood for the next project, Mark

Yes, Mark, infloor heating via PEX tubing in concrete (hopefully with a “wood-furnace/boiler/gasification/hydronic—the names keep changing).

yes, Pommy, i was planning on stick dry !!!

Indeed this may be a too big project. I probably need to do a sample to see what i am getting into….

Is there a problem with the wood flooring insulating the hydronic system? I would be concerned that the effectiveness of the system would be diminished by trying to heat through 3/4” or more of wood. What is the R value of the flooring? A buddy of mine just put in infloor heating and he was talking about the relative insulative values of different flooring types…I remember that ceramic was most transparent but do not remember where wood flooring ranked.

This is correct: a wood floor would insulate more then concrete or tile for instance, but depending on material less then a carpet floor. AS long as the surface below the hydronic is well insulate, the wood will probably only make the system “less responsive” (slower time to heat) but the amount of heat delivered to the room should remain the same. I am also considering some stained concrete but I do not think that they wouold be as pretty.
