Damping acoustic panel installation: 1.) Install the dragon skeleton (keel square wooden keel, light steel keel, etc.) 2.) noise filled cotton 3.) seal insulation boards, hand-cut noise damping composite boards, saw or sheet generally available handsaw to complete. If large plates be on-site cutting, we recommend using an electric saw tooth disc. Cutting blade is diamond saw. On round or curved cutting can be constructed using electric jigsaw. Available drill or hole saw any more than 10mm from the edge of the plate surface hole drilling or prescribing. (Before sealing insulation board, first posted a layer of insulation blankets better) 4) sealing and fixation. Use caulking gun peripheral smear acoustic panels along a width of about 5 mm soundproofing sealant, then the acoustic panel pushed to close the adjacent walls, floor, wall, it is extruded from the gap at the excess sealant applications scraper timely scrape. Fixed noise barriers, should be the only Ke acoustic panel with the original wall staggered as possible.
