I have woodchip throughout the house and am beginning the painful process of ripping it off and replastering. I was thinking about strutting the outter walls (cavity walls) putting fibreglass insulation and then drywalling them. My question is would I need to remove the woodchip before doing this or can I do it over the top of it? I just wasn't sure if it would change thermal properties of wall causing wood chip to mold or anything like that behind the drywall?
Thanks in advance for any advice
