Fletcher insulation has established itself as a trusted name in the Australian insulation market, offering thermal and acoustic solutions backed by over 90 years of manufacturing history. As one of Australia’s leading insulation manufacturers, the brand brings genuine local expertise to both residential and commercial developments across the country.
When homeowners and builders think about creating comfortable, energy-efficient spaces, Fletcher consistently ranks among the top choices. The company’s commitment to quality and innovation has made it a preferred supplier for Australian homes and development projects alike.
Fletcher Insulation’s range spans multiple categories, each designed to address specific thermal and acoustic needs. The product lineup includes several genuinely well-known lines that have become household names in Australian building.
Pink Batts represents the most recognisable product, delivering reliable thermal protection across R1.5 to R7.0 while maintaining installation characteristics that both professionals and confident DIYers appreciate. FirmaSoft Wall and Ceiling insulation batts are made to Fletcher’s proprietary low-dust formula, using up to 80% recycled content, and are perfectly balanced — soft and comfortable to handle, with a firm fit for easy installation. Soundbreak adds dedicated acoustic performance for noise control between rooms.
For fire-rated separating walls in NCC Class 1 multi-residential buildings, Fletcher Protect brings stonewool insulation into the range, purpose-built where compress-filling with mineral wool is required, delivering strong fire performance alongside genuine acoustic benefits.
Wall insulation represents a critical component of any building’s thermal envelope. Multiple Fletcher product lines address this need, each tailored to different construction methods and performance requirements.
Soundbreak provides dual benefits, addressing both thermal comfort and noise control in a single product, particularly valuable in urban environments where traffic noise and neighbour sounds can impact living comfort. For interior applications, Pink Partition insulation helps create quieter, more private spaces within buildings — especially valuable in office environments and multi-family residential buildings where comfort directly impacts occupant satisfaction.
Roof insulation plays perhaps the most crucial role in maintaining comfortable indoor temperatures, with uninsulated ceilings responsible for a significant share of a home’s heating and cooling losses.
Pink Batts ceiling insulation offers multiple R-values to suit different climate zones and building designs, providing reliable thermal protection that translates into genuine cost savings over the long term. Sisalation and Permastop handle roof and wall wrap applications, protecting the building envelope during and after construction.
Pink Batts ceiling insulation is the standard choice, arriving pre-cut to standard Australian joist spacing for quick, efficient installation — manageable for confident DIYers or straightforward for a professional install. Choose your R-value based on climate zone: R5.0–R6.0 for cooler regions like Melbourne and Canberra, R3.5–R4.0 for milder areas like Sydney. FirmaSoft and the wider Pink Batts range use a low-dust formula that minimises airborne particles during handling — worth knowing if you’re installing yourself in a confined roof space.
Standard stud cavities take Pink Batts at R1.5–R2.5 HD, fitting standard Australian wall framing without on-site cutting. Where noise control matters as well as thermal performance — party walls, home offices, media rooms — FirmaSoft or Soundbreak cover both needs in a single product.
Soundbreak is purpose-built for noise transmission between rooms, particularly valuable in urban environments where traffic and neighbour noise affect comfort. For interior partition walls in offices or multi-family buildings, Pink Partition delivers the same acoustic focus in a format designed for internal, non-structural walls. Both products focus on sound transmission specifically, rather than temperature control — for environments where concentration, privacy or noise comfort matter more than heating and cooling.
Fletcher Protect is the product to specify for NCC Class 1 multi-residential separating walls requiring compress-filled stonewool insulation — combining fire performance with genuine acoustic benefit in one installation.
Work through these factors in order to land on the right product for your project:
Application — Are you insulating a ceiling, wall, roof, or internal partition? Each has a different Fletcher product suited to it, covered in the application breakdown above.
Required R-value — Driven mainly by climate zone and whether it’s a new build or retrofit. Cooler regions typically need R5.0–R6.0 in the ceiling; milder areas are usually well served by R3.5–R4.0. Always check current local building code minimums for new builds.
Thermal vs acoustic requirement — If temperature control is the only priority, Pink Batts covers it. If noise transfer between rooms or from outside matters too, Soundbreak, FirmaSoft, or Pink Partition are built for that dual purpose.
Available cavity or ceiling space — Standard batts need standard cavity depth. Confirm your framing dimensions before ordering to avoid a mismatch between batt thickness and available space.
Fire requirements — Only relevant for multi-residential separating walls under NCC Class 1, where Fletcher Protect’s compress-filled stonewool construction applies specifically.
Building and compliance requirements — New builds need to meet NCC 2022 7-star NatHERS requirements; check your project’s specific obligations before finalising your product choice.
Once you’ve identified the right product and R-value for your project, browse our complete Fletcher Insulation range to compare available products and find the right solution for your walls, ceilings, roofs or acoustic application.
