I recently saw a house in the process of being constructed where an internal wall had been built out of 4" Thermalites.
This wall is almost 5m long and stretches across the property between the inner leaves which are also made of 4" Thermalites.
Either side of the internal wall in the exterior walls in close proximity to the internal wall are doorways and windows.
The internal wall also has a doorway in it with a Catnic lintol.
The wall is 2.75m high until it is restrained by some floor joists that create a first floor to one side of the internal wall.
It seems to me that this wall is rather slender considering its height and I would have built it using 6" blocks, particularly as it is so close to so many windows where it is tied to the inner leaf.
Does anyone know how to calculate what thickness of block should be used or know of any documents that would give this guidance?
