7,818kg of offcuts recycled in just 6 months. That’s a Mammoth Difference.

We’re turning what would otherwise go to waste into something useful again.

Through our insulation offcut take-back initiative, we’ve recovered 7,818kg of insulation offcuts in just six months, nearly 8 tonnes diverted from landfill and given another life.

It’s a practical step towards reducing waste in our industry, and a result we’re proud to be building on.

Reduce Thermal Bridging with Ceiling Batten Insulation

Mammoth® Ceiling Batten Insulation is designed to improve the thermal performance of skillion and truss roofs by insulating the ceiling batten space - helping to reduce thermal bridging through rafters and truss bottom chords.

Made from 100% polyester, Mammoth batten insulation is available in blanket and friction-fit section options. The friction-fit sections are typically installed between 35mm or 45mm timber ceiling battens, while in rondo systems, the framing can be suspended to allow a 45mm blanket to be laid over the top.

The ceiling batten cavity is often an underutilised space that can contribute significantly to the overall thermal performance of a building. For projects with larger roof cavities, Mammoth Ceiling Blankets may be suitable, while Mammoth Skillion Sections are designed for roof spaces with limited clearance.

Looking for insulation solutions for suspended or exposed ceilings?

Mammoth® insulation blankets provide a cost-effective and efficient solution for suspended ceiling applications in both commercial and residential buildings. Easy to install over ceiling grids, rondo systems, and other ceiling structures, they deliver reliable thermal performance where it's needed most.

For projects featuring exposed ceilings, Mammoth also offers semi-visual insulation solutions including Skillion Sections, Carpark Liner and Panel Absorber products. These options can provide both thermal and acoustic performance while helping reduce reverberation within large open spaces. Custom sizes, colours and finishes are also available to suit your design requirements.

Mammoth Skillion Insulation - designed for modern roof designs, built for lasting performance.

Every skillion roof is different, which is why Mammoth offers a range of insulation solutions to suit your project.

Whether you're designing a new build, undertaking a retrofit, working towards H1 compliance, or dealing with limited roof space, the right insulation system depends on the construction details. Factors such as rafters with purlins, vented battens, ply overlays, and target R-values all influence the best insulation solution.

Did you know Mammoth blankets can be double layered to reduce thermal bridging and maximise thermal performance?

Mammoth® Ceiling Blankets can be installed as a single or double-layer system to help meet NZ Building Code requirements. Manufactured in roll form, the second layer can be installed perpendicular to the first, covering the top of joists or truss bottom chords to minimise heat loss through these structural elements.

Designed to fit snugly between joists and trusses, Mammoth ceiling blankets help create a more energy-efficient home while delivering long-lasting, reliable performance. Read more at mammoth.co.nz

Warmth, comfort, and sustainability - all in one.

Mammoth® Ceiling Blankets are designed for new and existing roof cavities, delivering reliable thermal performance with R-values up to R4.0, or R8.0 when double layered. Made from recycled polyester fibres, they won't sag, settle, or irritate during installation, ensuring long-lasting performance for years to come.

Plus, every 100sqm of Mammoth ceiling blanket insulation can use up to 7,400 recycled PET plastic bottles* - helping turn waste into warmth while supporting a more circular economy. Read more here at mammoth.co.nz
