Hi all,
Bit confused about the way forward with my timber frame extension. I am just ready to plasterbord and i need to clarify whether i need to use the foil backed board for the ceilings between the internal floors or not. I know i need the foil for all the boards on the external walls, but i don't know about between floors. Also i have a single storey flat roof, should the ceiling of that have the foil boards too?
As a supplementary, should i bother with 9mm board on the ceilings and 12.5 on the walls or should i just make life simple and go for 12.5 all over. I guess the thicker boards are better for insulation.
Thanks in advance for any tips!
