A WALL SHOULDN’T JUST STAND THERE.
Most walls are assembled from multiple layers, with each material expected to perform one particular job.
H**p blocks approach the wall differently.
IsoH**p blocks can contribute to insulation, thermal inertia, moisture regulation, vapour permeability and acoustic comfort.
And they continue doing those jobs every day the building is occupied.
Your walls experience afternoon heat, cool nights, indoor humidity, cooking, showers and changing weather.
A vapour-open h**p-and-lime wall can interact with those changing conditions as part of a correctly designed breathable building system.
Combine it with compatible lime or clay finishes and the entire wall can work together.
So perhaps the question shouldn't simply be:
“What is my wall made from?”
Ask:
“What is my wall actually doing for the building?”
Because a wall shouldn’t just stand there.
It should work.

NOT ALL INSULATION IS DOING THE SAME JOB.
Most insulation is compared by R-value alone. But once it is installed inside a wall or roof, other characteristics can become just as important.
How does it manage moisture? Is it vapour permeable? What about acoustic comfort, indoor air quality, embodied impact and the experience of the installer cutting and handling it?
The comparison chart looks at Gramitherm alongside wood fibre, h**p fibre, cellulose, glass wool, polyester, spray foam and Rockwool across some of the factors that influence real building performance.
Every insulation has strengths and applications where it may be appropriate. The purpose of the comparison is not to pretend one number tells the whole story — it is exactly the opposite.
Gramitherm stands out because it combines strong thermal performance with excellent breathability and moisture regulation, very good acoustic performance, low embodied impact and comfortable installation characteristics.
Insulation is more than an R-value. The material behind the number matters.
We’ve published a more expanded explanation of the comparison in the KOSP Knowledge Centre, covering what each category means and why the complete wall or roof system should be considered.

WE’VE BEEN SOLD INSULATION AS A NUMBER. BUILDINGS DON’T LIVE ON NUMBERS.
A high R-value does not automatically mean a comfortable house at 4 pm on a 40°C day.
R-value is important, but it does not tell the whole story about how a building will actually perform through a long, hot afternoon.
R-value tells us how strongly insulation resists heat flow.
It does not tell us how much heat a material can absorb, how long it can hold that heat, or how quickly outside temperatures begin affecting the inside of the building.
Gramitherm grass-fibre insulation has a thermal conductivity of approximately 0.040 W/mK and a specific heat capacity of around 2,232 J/kg.K.
That heat-storage capacity contributes to thermal inertia and phase shift, helping slow the movement of daytime heat through the building envelope.
Gramitherm is also vapour permeable and hygroscopic, allowing it to contribute to moisture regulation within a correctly designed breathable wall or roof system.
So next time someone talks only about R-value, ask another question:
What will this house actually feel like at 4 pm on a 40°C summer day?
Energy ratings matter.
But real comfort comes from how the whole building performs.
Buildings are lived in — not just rated.

WHAT WILL TODAY’S INSULATION CHOICES MEAN FOR OUR GRANDCHILDREN IN 50 YEARS?
Think about the insulation being installed in a house today.
In 50 years, it may still be sitting inside those walls and ceilings.
That means the choices we make now can continue influencing energy use, carbon emissions and building performance long after today’s builders and designers have moved on.
For years, insulation has mainly been judged by the energy it saves after installation.
But what about the environmental cost of manufacturing it?
That is where materials such as Gramitherm® change the conversation.
Gramitherm begins with grass — a renewable plant material that absorbs CO₂ while it grows.
And once installed, it provides much more than thermal resistance.
It contributes to summer heat protection, moisture regulation, acoustic comfort and healthy indoor air quality.
No insulation product on its own is going to save the North Pole, South Pole or the climate.
But that is not the point.
The point is that millions of individual decisions made throughout the building industry add together.
A lower-carbon wall here.
A natural insulation system there.
A building designed to use less heating and cooling for decades.
Those choices accumulate.
The homes we build today could still be standing in 2076.
So when we choose a building material, perhaps we should ask:
What will this choice mean for our children and grandchildren 50 years from now?
At KOSP, we believe sustainable construction means thinking beyond the next project.
It means thinking about the world those projects leave behind.
Build for today. Think about tomorrow.

WHAT DID YOUR INSULATION COST THE PLANET BEFORE IT EVEN REACHED THE WALL?
For decades, insulation has been judged mainly by R-value.
That matters.
But R-value only tells us how the insulation performs after it is installed.
It does not tell us how much energy and carbon were used to manufacture it in the first place.
Glass wool and polyester can both reduce heating and cooling demand, but they still begin life with an upfront manufacturing footprint.
Gramitherm® starts from a very different place.
It is made from approximately 70% grass fibre, 20% recycled jute fibre and 10% synthetic binder, with an overall bio-based mass of about 86%. Gramitherm
The grass absorbs CO₂ while it grows, and Gramitherm’s environmental data shows a negative production-stage carbon balance.
So before it has saved one kilowatt-hour of heating or cooling energy inside the building, it has already started from a far lower-carbon position.
But carbon is only one part of the story.
Gramitherm also offers:
Excellent thermal insulation — λ 0.040 W/mK.
Summer heat protection — around 9 hours of thermal phase shift at 240 mm.
High heat capacity — 2,232 J/kg.K.
Moisture regulation — it absorbs and regulates humidity.
Vapour openness — vapour diffusion resistance factor of 2.
Acoustic comfort — reported sound absorption of 99% at 1000 Hz.
A+ indoor air quality — very low VOC emissions.
Resistance to fungal contamination under tested high-humidity conditions.
Versatile use in walls, floors, ceilings, attics and roofs. Gramitherm
Then there is installation.
Glass wool is a man-made vitreous fibre product created by melting glass and forming it into fibres. Safe Work Australia recognises inhalable fibre and dust exposure during handling and sets workplace exposure guidance for glass wool. Safe Work Australia
Gramitherm is a soft, semi-rigid grass-fibre panel that is lightweight and easy to cut and fit.
That means a cleaner and more comfortable installation environment, without the same mineral-fibre dust issues associated with glass wool.
That matters to installers.
And it matters in homes, schools and workplaces where these materials remain hidden inside walls and ceilings for decades.
So perhaps the real question is no longer:
“What R-value am I buying?”
It should be:
“What material am I putting inside this building, how was it made, how will it perform, and what will be left behind in 50 years?”
At KOSP, we believe insulation should reduce operational energy, lower embodied carbon, regulate moisture, improve acoustics and contribute to healthier buildings.
Gramitherm — natural insulation doing far more than simply insulating.

Watch for our follow-up: what today’s insulation choices could mean for the planet our grandchildren inherit in 50 years.

e often think of a wall as structure, insulation and a finished surface.

But the materials selected for that wall can influence much more — thermal comfort, moisture movement, acoustics and the way a building responds to changing indoor and outdoor conditions.

That is why KOSP is increasingly focused on complete wall systems rather than individual products.

H**p blocks, natural fibre insulation, clay-based panels and our developing Naichr wall and ceiling systems all approach the building envelope differently from conventional lightweight construction.

The interesting question for architects, builders and designers is no longer simply:

“What material can we use?”

It is:

“What do we want the wall to actually do?”

As construction moves toward healthier, lower-carbon and better-performing buildings, we believe that question is going to become increasingly important.

IT’S NOT ROCKET SCIENCE — SWAP THE BRICK FOR A H**P BLOCK

WA is dealing with clay brick supply constraints right now, and HIA has confirmed shortages are affecting the market.

At the same time, IsoH**p blocks are available in thicknesses from 75 mm through to 360 mm, so there is a wide range of options for internal walls, external walls, insulation and high-performance construction.

Here’s how I’d do the three posts.

WA BRICK SHORTAGE? IT’S NOT ROCKET SCIENCE — SWAP THE BRICK.

WA builders are dealing with clay brick supply constraints.

But building a wall doesn’t have to mean waiting for the same old material.

IsoH**p h**p blocks come in thicknesses from 75 mm to 360 mm, giving builders and designers options for internal walls, external walls, post & beam infill and high-performance wall systems.

You’re still building a solid wall.

You’re simply replacing a conventional clay brick with a h**p-based block that can bring additional benefits into the wall itself.

Depending on the block thickness and wall system, IsoH**p can provide:

• thermal resistance
• thermal inertia and phase shifting
• acoustic performance
• vapour permeability
• humidity regulation
• natural lime-rendered finishes
• solid wall construction
• fire performance as part of tested wall systems

The 360 mm IsoH**p block, for example, has published dry thermal resistance of around R5.37 m²K/W and a phase shift approaching 24 hours.

So when brick supply is tight, why simply wait?

Swap the brick. Build a better-performing wall.

WHAT IF YOUR WALL PANEL STARTED IN A PADDOCK, NOT A FOREST?
Most wall and ceiling panels begin with conventional raw materials and long-established manufacturing systems.
Naichr is taking a different path.
Our h**p-based panels are being developed from rapidly renewable natural fibre for applications including:
• Internal walls
• Ceilings
• Flooring
• Partitions
• Cabinetry
• Furniture
• Interior fit-outs
• Acoustic applications
H**p can be grown in a fraction of the time required to grow plantation timber, giving natural-fibre building products the potential to become part of a much more renewable construction supply chain.
But the story is not only about where the material comes from.
A modern building panel also needs to be durable, practical, moisture resistant, easy to work with and suitable for real construction applications.
That is exactly where the Naichr range is heading.
Naichr is being developed around Australian-grown fibre and Australian manufacturing, with ongoing product development and testing supporting the next generation of natural-fibre building materials.
Maybe the future of construction does not start in a quarry or a forest.
Maybe some of it starts in a paddock.

WA BRICK SHORTAGE? KOSP HAS H**P BLOCKS. NO Brick Shortage Here

WA’S BRICK SHORTAGE SHOULD MAKE US ASK A BIGGER QUESTION:

Why are we still relying so heavily on one way of building?

Western Australia remains one of the most brick-dependent housing markets in the country, while current construction activity continues to put pressure on both brick supply and bricklaying trades.

That pressure is being felt through longer lead times, constrained labour availability and ongoing program risk for builders and developers.

At KOSP, we believe this is exactly why the industry needs to broaden the materials and systems it considers.

IsoH**p h**p blocks are available for WA projects and provide an alternative to conventional brick wall construction for:

external walls
internal walls
post & beam infill
residential and commercial projects
breathable, natural wall systems

H**p blocks also bring thermal performance, thermal inertia, humidity regulation and acoustic comfort into the wall itself.

The point is not that one material should replace everything.

The point is that Australia needs more building options, stronger supply chains and less dependence on a narrow range of conventional materials.

When there is a shortage of the material everyone relies on, the smartest response is not simply to wait longer.

It is to ask:

What else can we build with?

NEED TO REDUCE NOISE?

KOSP is developing Naichr acoustic panels designed to provide a practical, natural-fibre solution for noise control in residential, commercial and infrastructure applications.

Our current acoustic panel system has achieved approximately 36 dB sound reduction, helping reduce unwanted noise transmission while using predominantly h**p-based material.

Potential applications include:

• Boundary and privacy walls
• Residential developments
• Commercial buildings
• Workshops and industrial areas
• Roadside and infrastructure noise barriers
• Internal acoustic separation
• Other noise-sensitive environments

Unlike conventional heavy acoustic products, Naichr panels are being developed around natural-fibre materials with durability, moisture resistance and long service life in mind.

The aim is simple — effective acoustic performance without relying solely on traditional steel, concrete or mineral-based systems.

Naichr forms part of KOSP’s growing range of Australian-developed sustainable building products.
