  1. thanks guys...... when i have some spare time i will build a conventional room in a room so i can listen to movies and play sax and bass guitar without annoying close neighbours. i am also reluctant of adding too much weight onto my concrete slab as its only waffle construction.
  2. something to ponder .....if i had a room within a room within a room [with coolroom panels with a 2 inch gap between each ] would the rw be 27 or 48
  3. thanks for the comments so far. so far in my research ive discovered coolroom panels have a rw of 24 ie they reduce noise levels by about 24 db regardless of thickness a 2.4 mt x1.2 mt x100 mm thick panel weighs about 30 kg some of the plaster/ timber/ insulation/ green glue/resilient channel walls can achieve 55 to 60 db reduction , with optimised setup.
  4. hi guys .....just trying to understand why this wont work to reduce sound travelling out/in to a music and home theatre room .ie equal to standard quiet room construction..... room would be 3.6 x 6 mt x 2.3 mt high. one door [over engineered] panels are 1200 wide x 2400/ 3600 long x 100 mm thick https://www.ebay.com.au/itm/Sydneys-Cheapest-100mm-Thickness-Z-Lock-Sandwich-Coolroom-Panel-AU-Standard/362555370300?hash=item5469fbeb3c:g:owgAAOSwI7JcZNNo its a lot quicker to build than a timber / plaster/ insulation construction. help me to understand ..thanks. jeffp
