Construction Method Of Perforated Gypsum Board For Wall

First, stick a layer of AFC-10mm vibration damping pad and a layer of 3mm sound insulation felt on the original wall, build a light steel keel, fill the keel cavity with a layer of afc-35 sound insulation cotton or a layer of AFC-40kg sound insulation cotton, and then seal the afc-488 sound insulation board. Then use afc-9.5mm perforated gypsum sound-absorbing board for exterior decoration to achieve the effect of "external sound insulation and internal sound absorption". Use sticky powder and white glue caulking tape to paste the joints.
