I had to cut into the cavity wall of our bungalow some time ago and found a very loose packing of flock which suggests that the insulation is not that effective so is it possible to actually measure how effective a buildings insulation is and if so what sort of organisation does it?
I'm sure that I read somewhere that one should not just drop insulation in between the loft joists and then board over it. Is that a fact and if so how does on insulate a loft and board it?
