About Capiworld: Thermal and Acoustic Materials Made from Recycled PET and Natural Fibre

Capiworld manufactures ECO-AEROGELS™ thermal and acoustic building materials from two unexpected resources: post-consumer PET bottles and agricultural fibre. Every product is made for one purpose — to control heat and sound inside buildings without introducing respirable mineral fibre or chemical emissions into the spaces people live and work in.

Capiworld Australia Pty Ltd is the Australian arm of Capiworld Company Limited, supplying the full ECO-AEROGELS™ range to builders, installers, architects and specifiers across Australia.

Post-consumer PET bottles are sorted, washed and flaked, then extruded into polyester staple fibre. The fibre is opened, carded and cross-laid into an open, low-density web, which is bonded by heat alone before being cut, faced or laminated into finished batts, panels and rolls.

This is the proprietary ECO-AEROGELS™ process. Its open fibre structure holds a high proportion of still air — and still air is what resists heat flow and dissipates sound energy.

Stage	What happens	Result
1. Feedstock	Post-consumer PET bottles are sorted, washed and flaked	Clean recycled PET flake
2. Fibre	Flake is extruded and drawn into staple fibre	Polyester staple fibre
3. Web forming	Fibre is opened, carded and cross-laid	Open, low-density web
4. Thermal bonding	The web is bonded by heat — no chemical binder	Stable batt or panel
5. Finishing	Cut to size, faced or laminated as required	Finished product

 

Because Polycycle and PureSpace products are bonded by heat, there is no binder in the finished product. That means no formaldehyde-based resin to off-gas into the room, nothing to break down over the service life, and no curing smell to wait out. In emission testing to ISO 16000 and ASTM D6007, formaldehyde and TVOC were not detected.

The Agribase line applies the same web-forming principle to agricultural fibre recovered from pineapple leaves and banana pseudo-stems — by-products that are otherwise burned or left to rot in the field. As natural fibre does not melt, a bio-based binder is used in place of thermal bonding.

The properties below apply to the Polycycle and PureSpace ranges. Each is a measured result tested to a named standard. Agribase values are listed on the Agribase product pages.

Property	Result	Test standard
1. No respirable mineral fibre	100 % polyester fibre — no gloves, mask or protective suit required for installation	—
2. Bonded by heat alone	No chemical binder · formaldehyde not detected (< 3 µg/m³) · TVOC not detected (< 20 µg/m³)	ASTM D6007 · ISO 16000-3/-6/-9/-11
3. Surface burning characteristics	Flame Spread Index 0 / Smoke Developed Index 70 (Class A, US IBC) · AS/NZS 1530.3 indices 0/0/0/1	ASTM E84-23c · AS/NZS 1530.3
4. Dimensionally stable	No delamination · will not sag, settle or deteriorate in service	ASTM C167
5. Moisture and mould resistant	Water vapour sorption 0.32 % by weight · no fungal growth · low corrosion to steel	ASTM C1104 · C1338 · C1617
6. Circular by design	60–90 % recycled content · recyclable at end of life	—

Fire performance note: Class A under ASTM E84 is a US test classification describing the tested surface-burning behaviour of the finished product. The material is an organic polyester fibre and is not classified as non-combustible. AS/NZS 1530.3 results are indices from that test method and are not a Group Number under AS 5637.1. Confirm the requirements for your building with your certifier or fire engineer.

ECO-AEROGELS™ materials start life as a used bottle or a farm by-product, perform for decades inside a building, and can be recycled again at the end of service. Polycycle and PureSpace products carry a 50-year warranty under the Capiworld warranty policy. Manufacturing is covered by an ISO 14001:2015 environmental management system, no chemical binder is consumed in the PET lines, and site off-cuts can be recycled through the same route as the product.
