Hello Everyone.....I am new to the site and have just started my HT room planning. I have cold laminate floors above my future HT room which will be in the basement below. Has anyone ever put a layer of Safe and Sound WITH a layer of thermal insulation in the ceiling joists? I understand that safe and sound has no R value. I also plan on doing ceiling tile with fiber optics for a star ceiling so double drywall will not be in the plan. Is my thinking nutz or has anyone done this yet? Thanks in advance for anyones' advice....

Conrad

From what I've read here...there's no real benefit. Reach out to Ted at Soundproofingcompany. He's very straight forward and a great resource.

Safe and sound does not necessarily have a zero R-Value. Roxul just doesn't track the R-value because the purpose of safe and sound isn't necessarily for thermal comfort. It will have some thermal benefit in addition to the acoustical benefit.

Is it solipsistic in here, or is it just me?

It your floors are cold you should consider spraying foam in the rim joist area of ceiling joist assembly. Once you finish the room below The floor above will be as warm as the room below except for drafts coming in laterally around the perimeter of the house. The rim joist will be the weak link in thermal management.

As for your idea of using Roxul safe and sound with a suspended acoustical tile ceiling. It won't put a dent in containing the sub-woofer rumble of a Home Theater,

Thank you Jeff....this info is exactly what i was looking for. I sometimes don't understand the great lengths of sounding proofing , the AV guys get themselves into... If bass is going to bleed through star ceilings etc., why bother soundproofing?

Thanks again.

You can do a star ceiling it just needs to be inside a soundproof bunker.

Or look at a painted star ceiling that glows when charged by black lights. There are several here and they look amazing.
