Question How do I improve insulation?
Hello everyone, I recently purchased a steel framed house in Hertfordshire and am finding it difficult understand how the ventilation works. Essentially I'm looking to remove the compressed straw like internal wall blocks and replace them with modern (probably Kingspan) material. I can only see one external air vent (see picture) and no internal vents at all other than the open wall cavity in the loft.
My question is, can remove all internal blocks and replace without compromising the steel frame? The house is believed to a Trusteel 3M Mark 2 constructed during the 1960s. Are there any articles where others have done the same thing? What is the best approach to get the best results?
Many thanks to anyone who can provide answers.
