波哥繼續請教一下

Thanks 波哥，since the contractor will provide 5/8 drywall on the two side of the room, I will consider OSB next time just to alleviate the back and forth with current contractor. But I'm considering wether to add soundproof cotton for sound insulation, according to your advice, it doest make much difference correct?

• 像這個東西，三寸厚的棉氈，需要GUT牆然後重新做DRYWALL。 很貴，你看值不值得了。光材料就是三塊錢一尺。 -borisg- ♂ (178 bytes) () 03/23/2024 postreply 20:29:15
