As part of the kitchen refurbishment I am looking to insulate the floor whi ch at present is a suspended T&G floor on 100mm joists. I am looking at fix ing 25 X 25 battens to the bottom of the joists and dropping 75mm foam insu lation in between the joists. Any advice regards preferences between Kingsp an or Celutex or is it just a case of whichever I can get at the best price ?
