Quick fire questions part 2 – CIJA? | Ep.24

In this quick fire round of Can I Just Ask…, we rattle through four of the questions people ask most often about insulation. What’s the best type? How thick does it need to be? Can you install it yourself? And does insulation actually help with mould? We talk through why wood fibre performs so broadly across the external envelope, typical thicknesses for internal wall, external wall and roof applications (and the U-value thresholds that sit behind them), why a competent DIYer can make a genuine saving tackling insulation on a retrofit or self-build, and how a warmer internal surface helps reduce the risk of surface mould. A fast, practical run through the questions that come up time and again. Watch the full quick fire round below.
