Simply put, acoustic roll is an insulation roll which inhibits the transmission of sound. Unlike the majority of insulation products (which are purposed to protect against heat loss), acoustic rolls, as the name would suggest, are designed to reduce the volume of noise from both inside and outside your home. Otherwise known as acoustic partition rolls, these rolls are primarily designed for use in walls, floors and partition walls.
Acoustic roll is made from fibreglass (otherwise known as glass wool) and exhibits high acoustic performance thanks to its manufacturing process. The way in which recycled glass is spun results in a product that is packed with tiny air pockets. These pockets trap sound and prevent it from getting through the material.
Sound insulation rolls are light and flexible, making them easy to handle and even easier to install. We recommend acoustic rolls for people who want to reduce sound transmission between adjacent and horizontal rooms in their homes. You can also install acoustic roll in partition internal walls and floors.
The minimum density of acoustic rolls in the Knauf Insulation range is 10Kg/m3. We recommend Knauf acoustic insulation rolls for people who want to reduce sound transmission in separating internal walls, detail walls, internal floors, and commercial metal stud partitions.
Knauf Earthwool acoustic roll is 1200mm wide and pre-cut to create two 600mm wide rolls. This pre-perforated style means that the acoustic roll can easily fit between studs or joists at 600mm centres, which greatly reduces preparation time and maximises on-site effiency.
Some of the main benefits of Knauf acoustic roll are summarised below:
Isover glass mineral wool roll offers high acoustic insulation to meet acoustic requirements in all domestic and non-residential applications. Isover is one of the most trusted manufacturers of acoustic insulation. Like Knauf rolls, Isover acoustic partition roll APR is ideal for people who want to prevent noise bleeding from one room to the next. The rolls can fit between standard stud and joist spacings with ease and provide excellent acoustic performance.
Isover acoustic rolls are covered by the SpecSure Warranty. If you use the rolls as part of British Gypsum drywall and acoustic floor systems, you are guaranteed lifetime performance. Another testament to Isover's durability is the fact that the thermal conductivity of mineral wool products does not change with time. Experience has shown the fibre structure to be stable and the porosity contains no other gases than atmospheric air.
Some of the main benefits of Isover acoustic rolls are summarised below:
Sound waves travel through the air before they hit a surface. The waves are either reflected or absorbed based on the type of surface that they hit. The density of the surface also impacts the outcome.
When sound waves hit Isover APR insulation or Knauf acoustic insulation rolls, the fibreglass absorbs the sound. The sound waves are trapped in the pockets of still air and are broken down before they can transfer to other parts of your home.
Each roll has a minimum density of 10Kg/m3. The denser the roll, the more it will absorb sound waves. If you want to reduce the transmission of sound from one place to another, you need to create as many barriers as possible. Barriers, like a dense glass mineral wool roll, will absorb the sound.
Acoustic insulation rolls are fire-resistant and rated A1 on the Euroclass scale. The Euroclass scale regulates the classification of insulation materials across Europe. An A1 classification means that the material is non-combustible and has the highest level of fire performance available on the market.
One of the main benefits of sound proof insulation rolls is that they are water-resistant. They are non-hygroscopic, which means that they will not absorb moisture. You do not have to worry about fungi, rot, or bacteria when you choose Knauf or Isover APR insulation.
Popular acoustic roll brands like Knauf and Isover pre-cut their rolls. If you need to create different shapes and sizes, you can use a few different methods. Cutting fibreglass insulation is an easy process, but you should always take proper safety precautions. Always consult with a professional before cutting insulation. We recommend using safety goggles, an apron, and a mask.
Mark your measurements on the roll before you begin cutting. Once you are happy with your outline, you can cut fibreglass insulation with a serrated knife, or a carving knife.
