Hi
I am building a single story L shaped side and rear extension (garage/kitchen/sun lounge). I am planning on using 100mm durox supabloc for the internal skin with dot and dab plasterboard.
Is there any advantage of using a 70mm cavity over a preferred 50mm cavity?
Is there any preferance of partial fill or full fill insulation? Would 30mm Celotex boards suffice?
Many thanks.
