We will soon be undertaking major renovation work on a property. Can you please advise why the loose fluffy type of insulation material works better for both sound and heat installation compared to the kingspan/celotex type boards in relation to INTERNAL walls in the house under ground to first floor ceilings?
I would've thought that the boards are better because they are more compressed /dense and will therefore have higher sound insulation properties as well as heat insulation properties within the rooms?
