I dont think u can use this golden laminate sheet on gypsum ceiling , i m not a expert though. In the ceiling of one of the room i have used mdf sheet and used the same golden laminate to highlight the border.

yes two fan, but yet not decided on design of living area, sheet work going to start soon, framing is already done 5' below RCC, tow points for fan and one point in between them for chandelier. pl suggest few good designs

well narrated, however, if you can add a photograph too ... it would have been more helpful to provide a suggestion

Hi Mr. Nitin, I am working as a Technical Sales engineer in one of Indian leading Acoustic Company. Everyday I receive minimum three calls for the same problems which you stated here. There two types of Sound transfer First is through Air borne like person Voice, speaker, sound horn. Second is through Structures like person knocking the door, neighbour people jumping the floor, elevator noise, etc. Yours problem comes under second type. This problem in ceiling concrete floor occurs due to lower steel usage and thickness of the concrete. The exact solution for this problem is to install the acoustic underlayment GETZNER AFM 23 under the Flooring tiles, which is specially designed for this kind of issue. But, it should be done during the construction stage of the building only. It can not be done after construction. If you use Acoustic panels and ceiling tiles, this products will reduce only the noise transferred though Air borne. So there is no solution reduction of this structural borne noise currently. Please don't spend your precious money in Acoustic Ceiling tiles or Wall Panels. Best regards, Bala Vishnu Murugesan
