slab wood table and radiant floors8/31
Good afternoon. I am building a 4x8 x21/4 single slab live edge pine farm table for my wife . The wood is approx 8% moisture as it sits in the shop . My question relates to radiant heat and this table . My house is heated with radiant floors with being stamped concrete of radiant floors in kitchen /dinning area. What can I do to prevent this table top from cracking via the heat and dryness of the floors ? Do I need to control the humidity in the space or would an expansion /contraction connection to the base work ? Or do I need both ? Thanks in advance . I am not a professional but a highly motivated disabled vet that uses my shop for relaxation.
Why do you think the radiant heat will cause problems?
Will your joinery accommodate seasonal wood movement?
I don't think I would worry about controlling humidity until you park a Steinway Grand next to the table.
No matter what your table design, you should always think about wood movement. Better to have it planned for and not need it, than need it and not have it.
If you want to post your plans or description and how you plan to handle movement, then you can get better answers.
Concrete is a great conductor of moisture so I'd be more concerned about a higher rather than a lower moisture content.
There is debate on the issue but my experience is that hot air heating creates a drier environment than radiant heat. Personally I think you shouldn't experience too many problems with shrinkage if you are starting at 8%.
David is correct though in saying you should plan in for wood movement. Depending upon where you are seasonal impact from the ambient exterior humidity levels could be more significant that the radiant heat.
