How it works
Jeanius Insulation sits within wall, ceiling, or underfloor cavities where recycled denim fibers trap air to moderate heat and dampen sound. The natural properties of denim provide excellent thermal resistance while creating a quieter, more comfortable indoor environment.

What Builders and Homeowners Say About Working With Respirabuilt.
Dan Miles
Ima and Will at Respirabuilt are your natural building experts, leading the way on creative solutions that close the gap on traditional materials and processes. The whole process has been excellent but most refreshingly the post sales support has been exemplary. Despite being remote Will has been able to jump on video calls to walk myself and our builder through some of the more nuanced or trickier situations. Worth opening a dialogue if you're thinking about building with hemp.
David Wright
After losing our home in the 2019 bushfires, we rebuilt with hempcrete for greater resilience. The unrendered internal walls have a beautiful sandstone-like texture with natural layering patterns. Temperature stays comfortable even in the high 30s without any air conditioning or heating. Visitors are immediately drawn to the aesthetics. It's a resilient, sustainable home that accentuates our bush site in a way a standard build never could.
Jamie Triplett
Just finished a build in Lake Tyers, using hempcrete cast and block method supplied from the Respirabuilt team, the wall came up great. Thanks Will for the advice and knowledge to get us started. Regards Jamie Triplett
Beatrice D.
Respirabuilt supplied and installed hemp blocks for our new bungalow — we were so impressed with both the product and their workmanship. Will provided complimentary consultation to our builder throughout, making the process seamless. The 120mm blocks were perfect for our inner city block. We now enjoy wonderful thermal and sound insulation and healthy indoor air. Will and Ima are so passionate and knowledgeable — helpful, responsive and always available. I can't recommend them highly enough!
Chris Nunnock
We used Respirabuilt hempcrete blocks in a block and cast build. Will and his team were invaluable from planning through construction. As an owner builder, the two-phase wall approach made the project very manageable. Now in fitout, the thermal performance has been amazing — consistently impressing everyone who visits.

We Build To A Higher Standard
Insulation is a decision you live with for fifty years
Most insulation choices are made under pressure — late in the build, with a contractor pushing whatever's cheapest on the truck that morning. Then you live inside that decision for decades.
Jeanius is for the builds where someone said let's do this properly. It's specified by architects who care about indoor air quality. Installed by builders who don't want to itch all afternoon. Chosen by homeowners who've read enough to know the difference between insulation that just hits a number on a spec sheet and insulation that actually contributes to a healthy home. Not to mention, it has the best sound insulation on the market.

Frequently Asked Questions
What is Jeanius made from?
Jeanius is made from recycled denim fibres. It's a natural, breathable insulation that diverts textile waste from landfill while delivering unbeatable thermal and acoustic performance.
What R-values are available?
Walls: R2.5 (90mm) and R4.0 (140mm). Ceilings: R4.0 (200mm) and R6.0 (240mm). We'll match the right spec to your build during the quoting process
Is it safe to handle without gloves or a mask?
Yes. Unlike glass wool or rock wool, Jeanius doesn't itch and doesn't release respiratory irritants. Most installers handle it bare-handed. Standard dust precautions are still recommended for ceiling-cavity work, but the chemical-itch experience of conventional insulation isn't part of the deal.
Is it fire-rated for Australian builds?
Yes. Jeanius is independently tested to AS/NZS 1530.3, meeting Australian fire performance requirements for residential and commercial applications.
How does denim insulation compare to fibreglass or rockwool?
Jeanius sits at a small premium per m². The trade-off: no itch, no chemical binders, better acoustic performance out of the box, full breathability, and a sustainability story you can put straight into your project
Where can I buy recycled denim insulation in Australia?
Buy direct from Respirabuilt. Jeanius is Australian made. Pick up free in Melbourne (Altona), collect from a Sydney or Brisbane depot, or have it delivered to your site, with install guides included. Build your own quote with our calculator.
