Hi, I am building a garden studio with partial fill cavity walls and am using celotex cavity boards.
Do I need to cover the top of the cavity as I build to prevent the cavity from filling up with rain water and to stop the celotex from getting wet?
Also will the celotex warp if it gets wet?
Thanks in advance.
