Acoustic R2.7 Insulation Batts

The acoustic performance of a batt is determined by the density (kg/m3) rather than the R-value. Some manufactures choose not to disclose the density of their products; however, a higher R-value of wall insulation generally indicates better sound proofing qualities. Excessive exposure to unwanted outside noise can lead to stress, sleep disturbance and has been linked to many other health complications. Road traffic is one of the biggest sources of noise pollution. Persistent noise within the home – for example music, tumble dryers, kitchen appliances etc. – can also have a negative impact on quality of life in the home.

Where To Install Acoustic R2.7 Insulation

There are two primary reasons to consider installing sound insulation in your home. The one is to reduce outside noise such as traffic, aircraft, barking dogs etc. – from entering the building interior. Typically, this means installing high density thermal and acoustic insulation in the external wall of the home, which forms an effective sound barrier. Sound insulation is also often useful within the internal walls of the home. Use common sense when considering this additional investment, and think long term, keeping in mind that it’s far easier and cheaper to install sound insulation during the new building project. Media/TV rooms, studios, bedrooms, bathrooms and laundries should be first on the priority list.
