Soundproof Acoustic Insulation

What Is Acoustic Insulation?

Acoustic insulation, otherwise known as soundproof insulation, is all about adding mass; and layers upon layers of dense materials. When sound waves travel through the air, they pass from material to material in vibrations. The more mass that a sound wave has to travel through, the fewer vibrations that will reach the other side of the material. A dense insulation roll or slab can dampen sound waves and cause them to dissipate, so you can no longer hear noises from other rooms, or outside.

The material that you choose to insulate your space with also has an impact on the volume of the noise that you hear. Glass mineral and rock mineral are the two most popular choices for noise insulation that can reduce noise pollution in your home. 

Rockwool RWA45 Slab

When it comes to soundproofing your home, Rockwool Acoustic insulation is simply unrivalled. Rockwool Insulation is the UK's leading manufacturer of sustainable, non-combustible stone wool insulation. With 0ver 80 years in the game, they prioritise quality and care at every corner. Rockwool’s RWA45 range is made from rock mineral, which absorbs sound and provides excellent sound isolation between floors and internal walls.

These high-quality acoustic and thermal insulation resin bonded slabs not only do a cracking job of soundproofing, but they also feature phenomenal fire resistance properties - as proven by their outstanding Euroclass A1 non-combustible rating. RWA45 is also water repellent - promising maximum protection for the lifetime of your build.

Each slab contains layers and layers of dense materials for maximum sound absorption. They have a density of 45kg/m3, making them excellent for people who want sound-deadening insulation.

All the products in the RWA45 range are cut into 1200mm by 600mm acoustic insulation slabs. They can fit between standard stud partitions and joists with ease.

Acoustic Insulation Rolls

Acoustic insulation rolls are designed to improve your quality of life by dampening sounds from one level to the next.

Knauf Insulation is one of the most trusted manufacturers of sound-deadening insulation rolls. The acoustic roll in the Knauf Earthwool range is made from glass wool fibres (fiberglass insulation). Glass, unlike rock, is a good conductor of sound. The manufacturing process helps to create a material that is resistant to sound transmission.

When it comes to acoustic insulation, it pays to invest in dense, thick rolls. 100mm Earthwool acoustic rolls are the thickest sound-deadening rolls in the Knauf Acoustic insulation range. Made from glass mineral wool, they contain thousands of minuscule air pockets which trap sound as it passes through, muffling noise and thus reducing noise transmission. Knauf glass wool rolls have a minimum density of 10kg/m3.

Thanks to Knauf's innovative ECOSE Technology, this range of slabs is a lot softer and fluffier than its glass mineral cousins. Rolls in the Earthwool range are 1200mm and have perforations at 600mm for ease of installation. Like the Rockwool slabs, Knauf rolls are rated A1 (non-combustible) on the Euroclass scale.

Acoustic rolls are often perforated to standard measurements. You can simply roll the product out into your pre-measured floor space. Rolls are also ideal for uneven walls. They are flexible, meaning you can manipulate them to fit around pipes and even roof beams.
