Pradeep, plywood or Gypsum has little do with heat reduction . It is the air layer between the actual ceiling and the false ceiling that does bring the temperature down. So as long as you are having a gap of 4-6 inches between the two ceilings it shouldn't matter. Gypsum would be more cost effective. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore

I Understand. That's a common concern with my clients. But if you choose to have a 3-inch false ceiling, it will not kill the height. you need a minimum of 3 inches for the electrical conduits to pass. And as for the unhygienic environment, it is only created if you have a tray ceiling for cove light. If you install a plain ceiling after a thorough cleaning, there will be no hygiene problem. I hope this helps you all the best

Basically vox is used for outdoor area and gypsum is used for interior so depends where uh want to apply😀

This is living area and I want to hide this beam depth effectively without decreasing the ceiling height. It should be look in a good manner what type of ceiling would be applied which is economical with the normal thickness of ceiling. Location - Mumbai
