I've put some french doors in and now I need to brick up my old back door. The walls are double thickness, solid brick with no cavity and are rendered on the outside. I think I have two options:
1) Use an internal skin of thermal block and an outside skin of concrete block
2) Use concrete block only and lay them horizontally so that only one leaf is used but the wall thickness is then the same as the height of the blocks if used in the normal way.
I want to go for option because it's easier. Can anyone see anything wrong with this approach?
Also, I intend to use 3 or 4 ties on each side to tie the blocks into the existing walls. I'll also use DPM underneath the new blockwork. Is there anything else anyone can suggest?
Lastly, the conrete block I've chosen is the medium density stuff from Wickes. Is this adequate do you think?
Thanks for looking
