吹牛羊毛改造的内壁？
I have a client who is interested in getting loose fill mineral wool blown into the attic and interior wall and ceiling cavities (‘drill and fill’) of her 1986 builder-grade house, primarily for insulation in the attic and sound attenuation (noise between rooms and from plumbing). Absolutely does not want to pull off crown moulding/base/trim to add another layer of gyp. board or isolation clips.
I have suggested that this is probably a large cost for a fairly minimal STC improvement, and I’m unfamiliar with any modern blown mineral wool products. I can find one or two on google (roxul’s is discontinued, Rockwool, insul-fill). I’m also a bit concerned about weight on the gyp. when blowing it into a ceiling cavity.
我将开始召集代表对此做出的看法，但是我很好奇 - 除了纤维素或FG以外，有人做过钻孔吗？怎么走了？

A guy in my office had rock wool blown into his 1840s vintage antique 30+ years ago. It went reasonably smoothly, and has held up quite well. The only issue he had during the installation had to do with the framing anomalies, where the wall cavities were open to the floor joist cavities between floors, and a LOT of rock wool got blown between floor/ceiling joists before the contractor figured it out. The ceilings didn't sag from the weight, but the contractor spent a day figuring out how to block the joist bays without ruining the antique plaster ceilings. A 1980s house won't have those issues.
The technique doesn't vary too much from cellulose, and it's somewhat less dusty due to the fact that it doesn't come with or need fire retardents.
The density of open blown attic rock wool isn't dramatically heavier than fiberglass, and quite a bit lighter than cellulose, typically still well under 1lb per square foot @ R49. Open blown cellulose would roughly 2x that of open blown rock wool at any given R-value. Take a peek at this document:

如果目标是降低声音，请不要将其致密地包装到墙壁腔中，因为这会使它处于动态张力下，并从组件的一侧到另一侧进行更机械的耦合。分区墙中的新学校1磅密度玻璃纤维可能会更快，但是在房屋周围漂浮的空气纤维碎片的风险更大，直到墙壁密封为止。
嗨，Diyer在这里。
您提到管道噪音。我想，如果您在阁楼或爬网空间中裸露管道，将用较厚的橡胶果皮和粘液管面条隔离管道，更便宜，更有效。一段时间后，我更换了失败的1英寸的Poly Tube（我不跟你开玩笑），这是我的管道主，用1英寸铜，并用橡胶管绝缘覆盖。与泵相关的噪音从整个房屋中回荡变成非常适中的嗡嗡声。较少的热水温度损失或冷水管线缩合的奖励点。为了获得最大的好处，每次拉一个1/2孔管夹，以便您可以在整个运行中运行隔热材料并相应地尺寸。
另一个想法：她的热水器有一个膨胀箱吗？一个足够大的？一个足够新的？减压阀怎么样？我以前的房子两者都有问题，这引起了很多噪音，尤其是在灌溉运行时。替换服务寿命PRV确实减少了噪音。他们只有约10年的生活。扩展箱相同。这些是便宜又简单的物品，可能会有所帮助。
What's the insulation up in the attic look like in general? I can't believe that a modern depth of cellulose wouldn't address enough of ceiling transmission under the attic. Blow more cellulose?
什么是加热系统？强迫空气？跳管怎么样？有吗？我会先责怪那些。背对背供应怎么样？更多罪魁祸首。直接切入供应躯干线？那也会传播噪音。您确定没有螺柱湾回报吗？ I'd certainly be sure to identify those before blowing any stud bays? My old house had these. They also don't help with noise transmission but wall stacking after the fact is pretty destructive.
How about back to back outlets or switch boxes between hallways and bedrooms? Trying to address those might be inexpensive.
Can you tell if the interior door framing has a large void? Popping the door trim and using canned spray foam can really help reduce the noise coming around the door through the trim.
I think Roxul does an amazing job of reducing high frequency noise like voices or road noise (and not a ton for low frequency like bass etc) but it doesn't sound like you have any real opportunity to use Safe N Sound or Comfortbatt.
Instead of noise dampening the whole house, what about the central bedroom hallway (if it has such a thing)? Pop the trim and door trims in the hallway, comfortbatt all the bays, dampen around penetrations or piping. You wouldn't be addressing room-room but maybe that would provide common area-room noise.
这次即兴演奏的最后想法。在我的最后一个家中，我将一楼的地毯和油毡转换为硬木地板和瓷砖（带有水泥板）。我惊讶地发现，所有质量和强度都严重抑制了噪声的传播。我特别惊讶地摆脱地毯改善了声音情况。当然，现在有些噪音反弹，但是该建筑商1960年代的房屋的一般吱吱作响和纸张稀薄的噪音传播消失了。我什至没有使用软木塞衬里，绿色胶或ditra。质量层确实可以帮助某些声音。
I don't really address your question but I hope those ideas help figure out what will really help your client.
