I live in a duplex and have tenants living above me. I had to open my ceiling up due to some water damage and now want to take the opportunity to soundproof my ceiling as best as possible. Can I use the Roxul R22 Insulation I have from a different project for the sound acustics in my ceiling? My rationale is the R22 insulation is almost twice the thickness as the 16.

Need your professional advice. Much appreciated.

ROXUL insulation is at the heart of a successful basement renovation project. It will keep things warm, dry and comfortable downstairs - and help maintain the peace and quiet on the main floor.

Roxul Safe and Sound is intended for sound proofing and works well. However, be acvised that it will not block everything because the sould is also trasnmitted through the floor joists. The space between the joists will muffle the sound with the insulaton but just know it's not a cure-all.

Hi Phil!

When the space in-between the floor joists is filled with sound absorbing material, it will deaden the sound transmission from the floor above, to a degree. What types of noise are you hearing that you don't want to hear? Wood is a sound transmitter itself, and you can't change that, so if that's the way the noise is being made- on the floor itself -not a lot of difference. I say this because I have had clients that thought it was a noise eliminator, which it isn't. It will however make a difference in reducing some airborne sound from above. Please see manufacturer's warranty for their sound advice - no pun intended!
