IWI open fireplace

[jayc89]

I’m (still) planning how to tackle the internal wall insulation on our house.

 

Whatever method I land on, I’ll need to insulate the fireplace somehow. See pic;

 

 

I assume I’ll need fire rated insulation, covered with a fire rated board.

 

What would you recommend?

Mineral wool and standard plasterboard are non combustible.  I guess you could just do the bit at the back.
