家里要住老人，然后我自己也是觉轻的，目前的想法主要是想让二楼的主卧（Bed Rm1）和另一个大房间（Bed Rm 3）尽可能的安静，减少室外和室内的噪音干扰，二楼外墙是cladding材料，其他区域就正常即可
做完Basix给我的标配是如下：
-R2.0 Insulation to cantilevered floor to bedroom 1
-R3.5 Ceiling insulation throughout, excluding garage
-R2.0 Insulation between levels above garage (to rooms above)
-R2.0 to Internal walls of laundry, bathroom and upper bathroom
目前想的是给主卧的大窗户换成Clear Laminate 6.38mm/gap/4mm clear double glazing，这个报价是$1900
另外自己做了一些research，也不是太懂哈，大概看了一些就是说如果单单升级窗户其实效果有限，加隔音板隔音棉才是整体提升，所以考虑之后只有主卧换了双层玻璃，然后其他的这些就一起发给builder然后再做选择，以下是我发出去的3个问题，红色的是builder的回复：
1. Just another question with noise reduction, we have discussed glass wool (wall batts) before, is there any available upgrade on this e.g. to be installed thicker insulation.
Basix requires R2.0.
To upgrade from R2.0 to R2.5 is an extra $790
To upgrade from R2.0 to R2.5 high performance batts is an extra $2,240
Thicker batts, than the above, are not possible.
2. Would it be possible to use Gyprock Acoustic (soundchek) Plasterboard with Rondo furring channel to have better sound proofing.
Acoustic wall plasterboard, direct fix, in lieu of standard plasterboard to the external living area perimeter walls is an extra $1,710
Acoustic ceiling plasterboard, direct fix, in lieu of standard plasterboard to the living area ceilings is an extra $1,960
Extra to install and fix Ceiling Plasterboard to Rhondo furring channel to the living area ceilings is an extra $4,320 (note that this will reduce the ceiling height accordingly)
3. Or to have stud wall with installing acoustic insulation and acoustic PB
Thermal insulation is required to external walls for basix compliance. See the above for acoustic plasterboard costs.
请问大家觉得这个报价合理吗，这里面有哪几项是有必要升级的呢，或者可否只给这两个房间的insulation还有Gyprock做升级，再要一份报价，这样更划算些

有没有大神指点迷津啊

减少室内噪音还得换门。
有中央管道空调吗，换了门后小心在空调启动下每次开门都是体力活。
