                              Understanding Acoustic Insulation

                              At its core, Acoustic Insulation is designed to absorb, dampen, or block sound waves. This technology is not just for recording studios or luxury apartments; it's a practical solution for anyone aiming to minimize noise intrusion or contain sound within a specific area.

                              The Benefits of Acoustic Insulation

                              The primary advantage of installing Acoustic Insulation is the significant reduction in both external and internal noise levels. This can lead to:

                              • Protection from external noise
                              • Comfort and privacy
                              • Reduction of sound transmission and vibration passing through building elements
                              • Applications for both renovation projects and new builds
                              Acoustic Insulation

                              How much insulation do I need?

                              Building acoustics focus on sound transmission mainly through the perimeter wall, as well as internal walls, floors and ceilings.

                              Transmission loss (TL) or Sound Reduction Index (R) express the effectiveness of blocking sound, which is frequency-dependent.

                              This is expressed in decibels (dB). The higher the loss, the better the insulation works as a barrier to unwanted noise.

                              The amount of acoustic insulation roll, slabs, granulates or panels required will depend on the material you choose, the size of the area being insulated and how much direct, flanking and other sound transmission there is.

                              Add An Extra Layer or Replacing with Sound Resistance Plasterboard

                              This racket-reducing technique requires a significant investment of time and money, but it’s one of the most effective ways to quiet a room. Cover the existing walls and ceiling with an extra layer of 13mm Gyprock Soundchek plasterboard. And as extra protection against noise transmission, seal the new drywall with acoustic caulk.

                              Or more thoroughly, demolish the existing partition wall and replacing with 1 layer or 2 layers of 13mm Gyprock Soundchek. This high density plasterboard has improved sound transmission properties to help maintain the peace when used in residential and commercial walls and ceilings.
