Hi, i am new on the board, a self builder, timber frame, near Kendal, after some help.
Part of my new build will be natural limestone faced, some rendered (about 80sqm).
I propose to use render board rather than block, the question is what system?
The architects proposal is bluclad or aquapanel on battens with thin coat render system.
Someone has suggested the possibility of using a breathable woodwool 25mm board directly attached to the frame (to OSB and vapor membrane with no battens no air gap).
This carrier board will then be covered by a breathable lime render.
There are a lot of advantages in this, it adds insulation, increases structural integrity, gets rid of the air gap, insect meshes, and probably solves any expansion/contraction issues.
but
- Will it work?
- Is it permitted under building regs?
- Will it bring lots of grief?
Can anyone help me on this .... please
