What Are Acoustic Insulation Rolls?
Acoustic roll stops the transmission of sound. Often referred to as acoustic partition rolls, these rolls are often installed in wall and ceiling partitions. Unlike a lot of insulation products that protect against heat loss, acoustic rolls are made to reduce sound transmission. With acoustic rolls, you can reduce the volume of noise from both inside and outside your home.
Acoustic roll is made from fibreglass, which is also called glass wool and have a high acoustic performance. Recycled glass is spun into fibres and processed into an acoustic roll. Pockets of air are trapped between the fibres. Still air is a good insulator, and energy cannot easily transfer through still air to other materials. Thousands of pockets of air reduce the transmission of sound from one room to another. Acoustic roll can also protect your space from unwanted outside noise, while maintaining a good thermal conductivity.
Sound insulation rolls are light and flexible. They are 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 install acoustic roll in partition internal walls and floors.
Knauf Acoustic Insulation Rolls
The minimum density of acoustic rolls in the Knauf range is 10Kg/m3. We recommend Knauf acoustic insulation rolls for people who want to high acoustic performance to reduce sound transmission in separating internal walls, detail walls, internal floors, and commercial metal stud partitions. You can protect your spaces from unwanted sound pollution with ease when you choose Knauf rolls.
These acoustic partition rolls are easy to install. 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.
Some of the main benefits of Knauf acoustic roll is summarised below:
● Rated A1 (non-combustible) on the Euroclass scale
● Friction fits between studs
● Pre-cut for ease of installation
● Made using Knauf’s ECOSE technology, making them soft to touch
● It's manufactured density provide assured compliance with sound related building regulations
Isover APR Insulation
Isover is one of the most trusted manufacturers of acoustic insulation. Like Knauf rolls, Isover acoustic partition roll APR are ideal for people who want to reduce sound proof transmission between rooms in their own spaces and the outside world. They 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 a lifetime of performance.
Some of the main benefits of Isover acoustic rolls are summarised below:
● Up to 86% recycled content
● Global warming potential of less than 5
● Rated A1 (non-combustible) on the Euroclass scale
How Do Acoustic Insulation Rolls Work?
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 or the outside world.
SoundProof Insulation Rolls Density
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.
Frequently Asked Acoustic Insulation Roll Questions
Are Acoustic Insulation Rolls Fire Proof?
Acoustic insulation rolls are fire-resistant. They are rated A1 on the Euroclass scale. The Euroclass scale regulates the classification of insulation materials across Europe. It measures materials against a range of different tests to assess where they land on the scale. An A1 classification means that the material is non-combustible and has the highest level of fire performance available on the market.
Are SoundProof Insulation Rolls Water Resistant?
One of the main benefits of soundproof 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.
How to Cut Acoustic Insulation Rolls?
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, aprons, and masks as an added layer of protection against any accidents.
Mark your measurements on the roll before you begin cutting. Once you are happy with your outline, you can cut fibreglass insulation with shears, a utility knife, or a carving knife.
How to Install Acoustic Insulation Rolls?
Acoustic insulation rolls are lightweight and easy to handle. As the name suggests, acoustic insulation rolls come in a blanket that is rolled up. People who want to place the full length of acoustic insulation between floor joists can simply roll out the sheet and secure it in place.
You should follow all the standard procedures that you would when installing other insulation rolls. The first step to installing insulation is checking your surroundings. It is important to ensure that your space is free from leaks and rot. If your joists are not structurally sound, the chance of accidents increases. Once your space is safe, rolls push fit between the joists and lay across the top of them in the opposite direction.
Installing acoustic insulation rolls in stud walls is more complicated. First, cut the rolls to the correct size. The rolls should be snug against the studs but not tight. We encourage customers to use a vapour barrier over the rolls to prevent condensation.
Always consult with a professional before installing any insulation product yourself.
While acoustic insulation rolls are effective at sound reduction, insulation slabs - such as Rockwool RWA45 100mm - have higher densities and therefore provide superior acoustic performance.
