Hi,
Rockwool and mineral wool are same according to me. The glass wool is different than the mineral wool though. It is easily available, you will have to hunt at local hardware market sepcially shops or contractors dealing with insulation materials. Ducting insulators, oven manufacturers and air conditioning contractors are the people with whom you can check the availabilty. Please note that the glass wool is superior than mineral wool wrt density and insulating properties of the material, however for the said purpose rockwool should suffice.

All the best :)

Hi manu4panjab

listen carefully - you have a baby child and young family -

glasswool, rockwool, mineral wool - these are HEALTH HAZARDS - and i suspect, a deadly rose with different names.

PLEASE DO NOT PROCEED FURTHER!!

Yes Suri is right, try to avoid these materials. They are ok for industrial use but should be avoided inside the house due to health hazards.

Suri is absolutely right about these being health hazards. I have seen samples of all three and the least evil among them is glasswool. I just took out the sample of rockwool and mineralwool from its box and I started sneezing, they are also very itchy.

Having said this, I have still used glasswool in my Home Theater as it has the best acoustic properties. Buy from a reputed company like Twiga as they manufacture to very high quality standards. No amount of care is sufficient in handling glasswool. Flakes keep flying around. If you have to use glasswool, finish the work fast. Keep the room ready. Install the glasswool and close it with panels or boards the same day. Vaccum the room the same day. You can see on my HT thread that my carpenter is wearing gloves, air mask etc while working with glasswool. Ensure you also do the same.

I have a roll of acoustically transparent sheet of tissue like cloth made out of glasswool. Installing this on top of the glasswool prevents flakes from flying around when you open your panels for some maintenance work. Let me know if you need it and I'll send you some, I bought an entire roll and am still left with a lot.

ps: I read about the health hazards of glasswool etc, but I could not find any conclusive statement about its being a carcinogen (cause for cancer). But I also read somewhere that the facts may have been supressed as all American and European homes have been using fibre glass wool for their insulation(heat) needs. Any ideas??

When I was checking around, I heard some of these materials are at the verge of getting banned. In fact, I work for a company which is expanding its facilities very fast and I'm told that our facilities guys have decided against using these materials for insulation..

Currently, I'm taking help from the only AV dealer I have in my towm for acoustic treatment of the room similar to his listening room. He has used straw boards and I liked the overal experience there...

I came across this product on the internet.. thought you might find it useful.
It's called Ultratouch - it is made of recycled denim cloth - seems to be quite eco-friendly and kid-safe, and seems to have pretty good acoustic properties. Seems to be somewhat reasonably priced too.. though I don't know if it is available in India. It is also fire retardant and mold resistant.
