Our house is an Edwardian semi. There is part cellar and part crawl space under the ground floor. There are plenty of air bricks below the ground floor joists and floorboards. My understanding is that it's not always a good idea to put cavity wall insulation in as it can prevent air circulation, trap condensation, etc and cause damp problems. Am I correct?
What about newer additions to the house then? There is a brick built extension and adjoining that an orangery. Assuming they have concrete floors and damp proof courses put in when they were built, are we okay to put cavity wall insulation in these more modern areas?
