November 26, 20214 yr Hi We are renovating a bungalow and just starting to get down to some finer details regarding insulation. Obviously I would like to insulate the property as well as I can. Exterior insulation is not possible in our design, so we are planning to install 50mm PIR on the internal walls, however the cavity between the bricks is only 70-80mm and I'm almost certain there is some form of blown insulation in there (I could see some white fluffy insulation when I took a window board off) My question is how effective is this insulation? Is there a way of improving this insulation further during the build? Many Thanks

Looks like you have a blown mineral fibre, e.g. https://www.knaufinsulation.co.uk/products/supafil-40 With a thermal conductivity around 0.04W/m.K it is good enough that their is no cost effective replacement or anything you can do to improve it.
