Earthwool R2.7 SHD Acoustic Insulation Batts
Knauf Earthwool Sound Shield insulation is an effective solution for reducing the transmission of external noise into homes. Typically installed in external walls, it is also highly effective in reducing sound transmission between different rooms and offices. An R-Value of 2.7, known as ‘super hi-density’, is popularly used in internal walls around home theatre rooms and TV rooms. It fits tightly into a standard 90mm wall cavity and can also be installed in ceilings, particularly in buildings located beneath a flight path. It can be installed alone or in combination with an additional layer of thermal insulation, depending on the required R-rating.
Environmentally Friendly Glasswool
The Earthwool Acoustic Insulation Batt range is a newer, safer, softer and more environmentally friendly insulation solution made from glasswool. These batts are a perfect option for DIY homeowners who wish to save money on power bills, maintain a consistent indoor temperature, and soundproof their homes. The R2.7 Earthwool Sound Shield is specifically designed to fit 90mm timber and metal frames, making it an ideal choice for homeowners looking for a cost-effective soundproofing solution.
The sound insulation range of Earthwool Insulation, as well as the entire product line, is composed of glass-wool insulation that is made primarily from sand and recycled glass bottles. Knauf has developed a revolutionary binder technology that utilizes ECOSE to bind together the extra-long, microscopically thin strands of glass fibers. This new technology eliminates the need for added colorants or harmful chemicals, resulting in practically no smell from the insulation. With its natural earth brown color and soft texture, Earthwool may seem like it comes from a sheep’s back, but it is actually a premium glasswool product designed to provide comfort and performance to both homeowners and insulation installers.
Reduce Noise with Sound Insulation
Consider the following questions when deciding if you need acoustic wall insulation:
- Which internal rooms are a priority? Typically, walls between adjoining bedrooms, bathrooms, and laundries are given priority.
- What is the thickness of the wall studs? This determines the maximum achievable R-value and sound insulation benefits.
- How much does noise transfer matter? If you have children at home, it may be worthwhile to upgrade to acoustic insulation.
- What about outside noise? If barking dogs, lawnmowers, and traffic noise are a concern, consider installing Earthwool acoustic wall insulation in outside walls.
A single layer of insulation installed in a standard 90mm stud can achieve a maximum R-value and kg density of R2.7. These are available in 430mm and 580mm widths to fit standard vertical stud spacing of 450mm and 600mm respectively. Acoustic insulation performance is rated in kilograms per cubic meter, and Earthwool Super HD has a solid 27kg p/m3 rating, providing exceptional thermal and acoustic performance. This makes it a popular choice for TV rooms and home studios.
Reduced Transport and Storage Costs
Earthwool Insulation is packaged in compression packed bags, which reduce the need for storage space and make them more affordable and easier to transport. The acoustic insulation batts come in durable, white poly bags that include easy-to-follow instructions for installation. If you plan to install the insulation yourself, it is important to first review Knauf’s DIY Safety Instructions and Precautions. Knauf Earthwool R2.7 Soundproofing Wall Insulation offers a cost-effective solution for thermal and soundproofing needs. The Knauf Insulation batts are odourless, fire-resistant, rot-proof, non-hygroscopic, vermin-resistant, and do not promote the growth of mould or fungi.
Choosing Acoustic Wall and Sound Insulation
If you are planning to build an acoustic wall or renovating an existing one, sound insulation should be one of your top priorities. Earthwool offers a range of Sound Shield Insulation batts with different thicknesses and densities to suit various wall cavities and acoustic requirements.
