Ceiling radiant

It looks like the tubing is under the lath. How thick is the plaster and what type of insulation is on top of the ceiling? It looks so comfortable and soothing.

50's ceiling radiant

Just thought I would share this photo of ceiling radiant as done in the days of old. I'm remodeling my kitchen and removed some soffit revealing the 3/8" copper tubing that was not embedded in the plaster. The condition of the tubing with exception to some tarnish is like new where the plaster was in contact with the tubing, a little scratch with the thunb nail reveals a shine.

NEAT !!!

Hello Gordy:

Interesting and neat picture of great radiant work.
You mentioned soffits.... was there originally plaster in the open area, or just a soffit wall?

Similar question..... is the wire mesh just for the corner section, to eliminate cracking which was a normal use back then, or is your total ceiling covered with mesh??

If your total ceiling is covered with mesh.... , which is closest to the brown looking board?? Mesh or copper..

I hope your project is going well and you are having fun.

Ciao.... Alex

Thanks for sharing!

That's a neat pic, and it looks as though the wire lathe is redistributing the heat it is receiving... copper heat emitters... not something one sees often anymore, except as supply piping in mechanical rooms. :-)

No this picture was taken after the partial soffit removal. The process must have been install rock lath, install tubing, frame, and rock lath soffit.

You are correct correct with your assumption corners inside and outside with a bullnose, what a beachy for demolition!

Copper is fastened directly to rock lath which is celotex brand. Be darned if I can find anything out about this type of rock lath looks like compressed would slivers. The plaster does stick though, can't peel it off the board.

Who says they don't use copper emitters anymore . I will submit pics of my radiant floor in the kitchen shortly.

That may well be the original Celotex. It's a by-product of extracting sugar from sugarcane.

celotex

It sounds about right Mike. The fibers look kinda like wood slivers. Do you know anymore about the product?
