    Re: Weather and sound insulation questions.

    For acoustic performance, Fiberglass = mineral wool = cellulose = polyester = cotton. If you have some insulation there now for crying out loud keep it. Just add more thermal insulation to what you...
  4. Re: Old Victorian with no subflooring on upper floors

    Have a look at this article to isolate that floor: http://www.soundproofingcompany.com/solutions/soundproofing_ceilings/

    Standard R19 is all that is needed for insulation.

    Re: Soundproofing an old factory ceiling

    You'll want dometing more massive for larger holes. Sound can pass through low-mass foam fairly easily. I'd suggest attaching heavier 5/8" drywall or plywood before adding insulation to the cavity...

    Re: Soundproofing an old factory ceiling

    Mass is about all you could do. Use drywall and framing, as this is about the least expensive source of mass

    Re: Soundproofing an old factory ceiling

    I agree. I would point out that these massive floors should hold back a fair amount of noise just due to their mass. The fact that you can hear things so clearly makes me think there are cracks and...

    Re: spray foam insulation decisions

    Small point here. Foam is better for thermal insulation but NOT for acoustic. Foam is too dense, and will couple the two outer surfaces of the wall.

    Re: Soundproofing

    I would suggest using the least expensive insulation available. Independent tests show they all work similarly as long as they are not compacted.

    Re: Soundproofing

    +1 Foam is great where the joist cavities meet the outer wall. Seals them so well. The balance of the ceiling should be fiber, which when sealed up behind drywall will work best.

    Hi Sunny,

    The cotton is no better than standard fiberglass from an acoustics perspective. There's no independent lab data that supports anything is much better than plain old fiberglass in a stud...

    Re: Insulating & Soundproofing a Ceiling

    Surprisingly, foam is not great to use in a sealed cavity for sound isolation. It's the best there is for thermal, however bad for acoustic. The issue is that there is insufficient surface area to...

    Re: Bathroom Renovation-Insulation Questions

    1. Foam is distinctly better for thermal isolation, quite bad for acoustic isolation.

    2. Mineral fiber is not better than fiberglass for in-wall damping of resonance.

    Re: Noisiest Ceiling Ever - Help!

    Well, the most expensive system would use pre-damped "soundproof" drywall, and that would be a waste of funds. So the most expensive isn't any better at all.

    Re: Insulation of basement ceiling

    That's not to say the vapor barrier is in conflict with sound isolation. If soundproofing is one of the goals, and paper is convenient to attach to the joists, then go ahead.

    Re: Soundproofing

    This is Part E of the new unified EU building code. Here in the US we'd do well to look at the seriousness with which Europe treats noise. Much better sound isolation standards.
