Stone wall + wood frame = 2 leaf?

If my room is made of 1ft thick stone/concrete, is it correct that the stone wall is considered to be 1 leaf? Does this mean that a single wood frame wall, with a double layer of plasterboard on the inside would be the 2nd leaf and would achieve good isolation? I bought Rod Gervais book and it doesn't explain what to do with stone outer walls at all. Confused... :? Skip

If the brickwall is solid it's indeed 1 leaf. Adding the woodframe with pannels makes it, indeed, 2 leaf. 1 foot brickwall gives good iso, it's a whole bunch of mass. A stone brick is about 2 time the density of gypsum.

Skip, I couldn't cover every construction technique used world wide - so I stuck with the basics. Besides - I knew I would be around to answer questions like these. A stone foundation is exactly the same as a concrete foundation - a single leaf. So just make believe it's concrete - deal with it exactly how I show you in the book, and you'll be fine.

Thanks very much for the info guys. @ Rod, your book overall is the most helpful one I have read. I got answers to more questions in your book than a year on various forums waiting for replies that sometimes never come. I highly recommend it to anyone wanting some well described facts, figures & pics. I only recently discovered that many, many houses in the USA are made of wood, whereas most places over here are brick. Thanks again for the help. Skip
