Pink® Soundbreak™ R2.5 Acoustic Wall Insulation (90mm)

Most homes use 90mm stud walls, and that’s where Soundbreak R2.5 fits. It’s a denser batt than standard insulation, built to absorb sound inside the cavity, so less noise passes through the wall. You also get a strong R2.5 thermal rating, which helps keep the room comfortable year-round. It’s made in Australia by Fletcher Insulation and backed by a lifetime warranty.

How much quieter?

Fletcher’s data sheet says a typical internal wall on 90mm timber studs with 13mm plasterboard each side achieves around Rw 32, and that adding Soundbreak in the cavity typically lifts it to around Rw 42. A 10-point increase is described as a doubling in perceived sound isolation. Results vary with the wall design and installation.

Installation tips

• Follow the Pink Batts installation guide for walls and the relevant building requirements. Pink® Batts Wall and Ceiling Installation Guide
• Cut batts slightly oversize so they friction-fit between studs.
• Fill the cavity fully, without compressing the batts, and avoid gaps at the corners and edges.
• Wear gloves, long sleeves and a dust mask when cutting.
• Check the NCC requirements for your climate zone.

FAQ

Will Soundbreak soundproof my room? No. It reduces noise transfer, but results depend on the whole wall system, including plasterboard and sealing.
Why is it green? Fletcher now makes Soundbreak in a distinctive “Serene Green” colour to tell it apart. Performance is the same, and older stock may be pink.
How many packs do I need? Measure the wall area, subtract windows and doors, divide by the coverage per pack and allow a little extra.
Can I collect in store? Yes, click-and-collect is available at checkout.
