Rocksil RS3 or Owens Corning 703 are more or less equivalent. 40mm and 70kg/m3 would work fine too. The difference installing any acoustic treatment compared to the untreated room will be huge so don't worry too much about the specifics of the panel material you use, Mineral wool of around 60kg/m3 and 50-100mm thick seems to deliver the best overall bang for buck combined with ease of use but all of those things have been used successfully as well as various forms of foam, hemp matting sheep's wool and any number of other materials.

Try looking for Knauf Earthwool as well, it's the same stuff with a different brand name.
As Sam says, anything around 60 is good, everything is a compromise somewhere so don't worry too much about the fine details.

Sam and Drew have covered it really, but it might be worth a mention that from a practical point of view it'll probably be better to end up with slightly higher density rather than lower. Once you start getting down below 60kg/m3 then you'll find that it doesn't support itself in the frame quite as well and will need extra bracing/mesh to keep it in shape.

A good point, RW3 is rigid enough to be self supporting :thumbup:

Hey Guys,

I just wanted to thank all of you for the advice.

I used wood that was about 3.8 cm thick and about 11cm wide. They came in 4 meters long and I just cut them down to the size I needed. Not the best wood in the world but the price was right, it wasn't too heavy and it was easily available to me

For the Rockwool - I went with Rock plus Premium Nu - it was the best I could find,here in France, 10 cm thick and about 65K on density

For the panels: I just built the size I needed, drilled some holes on the side, and added about 4 cm of space behind the panel and another 1.5 cm from the panel to the walls.

I couldn't have done it without your help and I just wanted to say thanks to everyone.

Nicely done, and isn't there a real feeling of satisfaction when you can DIY something? 8-)
