Question Will Roxul Safe N Sound make a difference ?

Hi everyone,

I am finishing my basement and 1 of the room will be my own personnal HT (HD Projector, 120 inch Screen, Onkyo 708, 5.1 speaker system (not purchased yet).

Since my ceiling is not yet completed, i was thinking of putting Roxul Safe N Sound on my ceilling. Since they are 3 inch thick, i was thinking of putting 2 layers.

My concern is as follow. Since my basement is not that big, I will leave everything open, my HT Room wont be closed, no doors. Will the ROxul make any difference ? Is it worthed to spend 300$ for this ?

Thanks for the advise.

Regards,

300 dollars sounds too high. Safe N Sound is the same thing as Mineral Wool insulation. I'd just get R19 and roll it with the paper toward the room on the ceiling you would get the same effect for far cheaper.

Agreed. The difference between Safe N Sound and standard fluffy insulation isn't that much honestly. Save your money for more important things.

On another topic - are you sure you want to leave the theater open? If you want to post a quick sketch with some dimensions, we'd be happy to take a look.

Re: Will Roxul Safe N Sound make a difference ?

Safe n Sound in my area is pretty close to the same price as regular insulation. It might be about 10% higher. I believe the difference between the Safe n Sound and regular Roxul is just that the former has been tested and rated for sound suppression.

As far as making a difference. It will deaden the sound transmission between the floors within your room. Sound will still flank through your open doors. I guess it depends on the floor plan above your theater and if you want to deaden the sound from above. Part of the goal of soundproofing is to stop noise from getting in to your theater.

If you can afford it, I would do it. you may add doors later on or finish the rest of your basement. It's a lot harder to retro-fit after the drywall is up on the ceiling. Even one layer of insulation will help.

Re: Will Roxul Safe N Sound make a difference ?

My issue is that my basement is not huge....so if i close it, it will look small...and my Wife (yes my wife ) dont want to go there and nothing I can say will convince her.

That being said, the kitchen will be upstairs so sound might not disturb but i still want to find a way to reduce it.

You guys really think that if I dont close it, it will make a really difference ?

Ill try and make a sketch (pretty basic) and post it here.

Thank you everyone for your help.

Most of us here have to deal with the WAF so we feel your pain.

Do you plan on drywalling the ceiling and walls or having a drop ceiling?

If you're going to drywall the ceiling, then yes - leaving it open vs closing it will have a huge impact.

Thanks bpape. That being said, with putting roxul and closing with gypse, sound will go up from the section after. Is that correct ?

If so, will it till reduce the sound ? How much? 40-50% ?

Thanks!

Re: Will Roxul Safe N Sound make a difference ?

Insulation and drywall will be pretty effective. Assigning a hard percentage is pretty tough to do. If you fir the drywall off the joists a bit, you're looking at being able to get around a 50db reduction or potentially a little more. That's an overall number though and it's different at different frequencies. The bass is the hardest to stop and the firring will help with that.

Also, to be clear, my post above was referring to walling off the theater rather than leaving everything open. Sound travels everywhere. Doesn't do much good to close off most areas and isolate them if you have big 'holes' in the room for sound to escape.
