Construction Method Of Perforated Gypsum Board For Suspended Ceiling

First, stick a layer of AFC-10mm vibration-damping pad and a layer of 3mm sound insulation felt on the original suspended ceiling. Use elastic hooks for suspension reinforcement for shock absorption and install light steel keels. 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.
