发帖数: 5681 | 1 这房子不正常。 几年前我看过这种的房子。 结果是builder偷工减料而且又没有申请
city permits. 结果下一个买家要interior wall 全拆地才可以通过inspection for
city permits. 你应该问一下卖家这个房子有没有all permit from the city.
假如你真的想买， 可能要注射insulation foam。 每两尺在墙上打一个洞， 注射
insulation foam。 房顶就用隔离棉。 |

的outlet给拆了， 看外墙里面有没有insulation. 小心不要电到自己。 |

有便宜点的换insulation contractor and contact.

发帖数: 11 | 4 60年代的ranch，attic上是原来的insulation，一团团的，看着很脏，想着要不要把原
来的insulation换了。
问了个contractor，要好几千的样子。就是不知道这钱值得花吗？
不知道有没有换过的同学来说说，换了以后能凉快很多吗？
家里有几件房朝南。去年装了空调，今年好像开过一次，某周末下午家里80多度的时候

发帖数: 1246 | 5 最大的可能是crawl space太潮，以前的insulation全都烂了，所以卖之前换掉为了有
个好卖相，但如果潮的问题不解决，将来还是要烂的，除非用那种有铝膜的insulation
，会比较耐久。 |

Foam insulation has history of damaging shuttle

NEW ORLEANS -- The foam insulation that peeled off as the Columbia lifted off
Jan. 16, striking the shuttle's left wing, has been a headache for NASA

发帖数: 110 | 7 march meeting回来，最大的感觉就是toplogical insulator现在火的不行，大有取代
graphene之势，老板现在也盘算着想趟这淌水，但我总有个疑问，这东西以后前途真的
大么？
我们组做凝聚态实验，graphene目前也做的挺顺手，虽说graphene也是个成功的炒作，
但也算是一步步逼近工业应用了，而且本身物理上可以研究的也很多。toplogical
insulator就不太熟悉，打听了一下，目前做实验的形势就是：材料难找,transpot实验
难做，很多高水平的组在抢做实验的credit。
还是看一下形势再说吧，何况graphene估计还能火个一两年。。。 |

不是可能是肯定跟garage有关, 而且很有关系.
你LD说得没错, vaulted ceiling上面就是屋顶, 你跑attic里家insulation,肯定对主
卧没啥帮助的.
偶觉得,你在你的主卧加个电暖气比较实用,简单些, 再加个加湿器平衡下湿度就成了. |

发帖数: 5901 | 24 By the way, be careful with fiberglass insulation. I'm still feeling itchy in my throat after like a week. That stuff isn't much safer. Actually, I think cellulose is way better than fiberglass. I wish I had it in my house, but it isn't.
When look at stats, don't just be assured by the low fatality rate. You can be very miserable and ... alive. |

发帖数: 5901 | 25 Of course not. It's just that last night I discovered this particular case
about fiberglass insulation. I can see lots of people here know even less
about the danger of fiberglass than I did (before I made this discovery). |
|
j***b
发帖数: 5901 | 26 I also judge from the way an argument is made.
For example, those argue against cellulose say that it can't be guaranteed that every single bag of the insulation is well treated with chemical so that it won't burn. This is typical fear tactic. This argument can be used in anything. So anything is unsafe if this argument is valid.
I also love the way wiki is always discredited left and right. Like it's just a useless website. |

发帖数: 5901 | 28 Actually, if you compare cellulose against fiberglass, the fact is that
fiberglass insulation has no reason to be still in the market. Cellulose
simply does everything better than fiberglass. |
