Naichr Wall & Ceiling Board Installation
​
Naichr wall and ceiling boards are installed using standard plasterboard-style dry-lining methods to suitable framing or battens.
​
Boards are fixed using screws and Bostik Wallboard Gold adhesive, with screw fixing as shown in the Naichr technical sheet. Where board joints do not land on studs or framing, use stitching battens / backing battens to support the joint.
​
External corners should be finished with suitable ali corner beads that allow panel to fit into beading, to eliminate flushing. Final surface finishes may include suitable mineral, lime-based coating systems, depending on the project requirements.
​
More detailed installation guides, fixing layouts and joint details are being added. Contact KOSP for the latest Naichr board technical sheet or project-specific advice.
Naichr board corners and wall junctions can be finished in two ways, depending on the desired look of the project. For a conventional finish, aluminium beads can be used and flushed in a similar manner to standard plasterboard systems. For a more natural architectural finish, proud timber beads or future Naichr beading options can be used to highlight external corners, internal corners and top-of-wall details, this can be a stronger system on corners . This gives designers and builders the choice between a clean blended finish or a visible feature detail that adds warmth, character and a distinctive natural appearance to the wall system.
​
Naichr 8 mm board sits in the same broad supply-cost category as specialist MgO, fibre cement and structural board products, while offering a natural hemp-based internal lining option.
Some MgO and cement-based boards can be dusty, abrasive and uncomfortable to cut or handle, particularly where reinforcing mesh or mineral fibres are present. Naichr board systems are intended to provide a more natural internal lining option with easier handling, cleaner installation and a warmer architectural finish.
Naichr Boundary Fencing Installation
​
Naichr boundary fencing is designed as a modular post-and-panel system for fence heights up to approximately 1.8 m, subject to site conditions, wind exposure and final engineering requirements. Before installation, set out the fence line and position posts to suit the required panel size. The Naichr system is designed around generally equal panel spacing, with post centres allowing approximately 5 mm clearance greater than the panel width, helping avoid small cut panels at the end of a run where possible. On last panel you may need to trim panels or rails to the required size
​
Post holes should generally be dug to a minimum depth of 600 mm, with final depth to suit soil conditions, fence height and wind loading. Naichr posts can then be positioned level and true. Posts may be set using suitable concrete or stabilised backfill methods, depending on project requirements. Unlike timber posts that can shrink, rot or create water traps inside concrete footings, and unlike metal posts that can corrode over time, Naichr posts are designed to be resistant to moisture damage, rot, rust and termites.
​
Installers may set all posts first where they are confident with the layout, or work progressively panel by panel. Once posts are secure and aligned, Naichr panels or rails slide into the receiving channel of the post. Panels are then seated into position and secured with stainless steel screws as required.
​
Where the fence line is on sloping ground, the bottom panel may be cut to suit the required angle. This may alter the visible fence height at one end of the panel or create a gap beneath the panel depending on the fall. A practical method is to run a tight string line approximately 150 mm above the ground, lifting the line where the slope changes direction. The fall can then be measured using a level or laser. For example, if the total fall is 400 mm over five panel bays, divide 400 mm by 5, giving an average fall of 80 mm per panel. This means one end of a panel may sit close to the ground while the other end may have an approximate 80 mm gap underneath, depending on site condition, this will allow you to know what the gap is and take required steps to cover gap a product that suits ,bricks or make a small concrete or timber plinth
​
After completion, level disturbed ground where practical, remove excess soil, and wipe down any soil, cement or residue from the Naichr posts, panels and rails. Final details may include end posts, corner posts, top finishes, caps or trims depending on the selected Naichr boundary fencing system.

​
More technical articles are being added, including, moisture control, thermal performance, acoustic performance and building systems. Contact KOSP for project-specific advice.
Why Modular Post-and-Panel Fencing Works
Modular post-and-panel fencing systems are designed to make installation cleaner, faster and more consistent. Instead of building a fence piece by piece on site, posts are positioned first and panels or rails are then fitted into the post slots to create a straight and repeatable fence line.
​
Naichr boundary fencing uses this approach with posts designed to hold panels or rails in the female section of the post. This helps simplify installation, reduce on-site cutting where panels are set out evenly, and create a strong, clean fencing system.
​
Because Naichr posts are not timber or steel, they are not affected by rust, rot or termite attack in the same way as conventional fencing materials. This supports long-term durability, especially around concrete footings and ground contact areas where many traditional fencing systems can fail over time.
​
More technical articles on fencing design, post spacing, slope installation and outdoor durability are being prepared.

Naichr Boards vs Conventional Plasterboard
​
Naichr wall and ceiling panels are designed as a natural internal lining option for projects seeking alternatives to conventional plasterboard.
​
Naichr panels are designed as a durable, impact-resistant internal lining option for projects where stronger wall and ceiling surfaces are preferred over conventional plasterboard. They are suited to homes, commercial interiors, modular buildings and high-use areas where everyday knocks, bumps and long-term performance need to be considered.
​
While plasterboard is widely used in standard construction, Naichr boards are suited to projects where natural materials, durability and sustainable building outcomes are important.
​
Naichr boards can be considered for healthy homes, renovations, commercial interiors, modular buildings and projects looking for more natural interior lining systems.
​
More product comparisons are being added, including hemp panels, insulation, acoustic systems, blocks, renders and conventional construction materials. Contact KOSP to discuss the best product option for your project.
Naichr Boundary Fencing vs Timber & Steel Fencing
​
Timber and steel fencing systems are common, but both materials have long-term maintenance considerations. Timber posts can shrink, rot, split or attract termites, especially where they are set into concrete or exposed to moisture. Steel posts can be strong, but they may corrode over time if protective coatings are damaged or if they are exposed to harsh ground and weather conditions.
​
Naichr boundary fencing is designed as a low-maintenance alternative using Naichr posts and panels or rails that are resistant to rust, rot and termite damage. The modular slot-in post design also allows panels to be installed in a clean, consistent way, helping create a neat boundary fence with a more modern finish.
​
For projects where appearance, durability and reduced maintenance are important, Naichr boundary fencing provides a practical alternative to conventional timber and metal fencing systems.

Hemp Board Panels Australia — Why Naichr Is Different
Australian construction has relied on the same familiar internal wall and ceiling lining materials for decades.
But building products are changing.
Naichr is developing a new generation of hemp-based wall and ceiling panels designed to provide a tougher, more durable and more sustainable alternative for modern Australian construction.
Made predominantly from hemp shiv fibre with a natural resin binder, Naichr panels are designed for use on internal walls and ceilings in residential and commercial buildings.
What Are Naichr Hemp Board Panels?
Naichr wall and ceiling panels are made from approximately 90% hemp shiv fibre, with the remaining content comprising natural resin.
The result is a lightweight hemp-based panel designed around familiar building and installation methods.
For a standard 2400 mm × 1200 mm panel, the current Naichr panel weight is approximately 10.7 kg.
That equates to around 3.7 kg per square metre, making the panel relatively light and easy to handle on site.
Why Look Beyond Conventional Plasterboard?
Plasterboard has been used successfully in Australian buildings for many years, but it also has limitations.
When exposed to significant moisture or water damage, conventional gypsum-based linings can soften, deteriorate and lose strength.
Ceilings damaged by leaks or storms may require complete replacement.
Naichr is being developed to provide a tougher alternative.
Its hemp-based composition is designed around:
-
water resistance
-
resistance to deterioration
-
resistance to rot
-
resistance to twisting and buckling
-
termite resistance
-
improved durability
-
long service life
-
resistance to everyday impact and damage
Rather than simply recreating another plasterboard-style lining, Naichr is being developed as a new type of natural-fibre construction panel.
Designed for Walls and Ceilings
Naichr panels can be used as internal wall and ceiling linings.
The aim is to make adoption straightforward for builders and installers already familiar with conventional sheet products.
This includes compatibility with common fixing and finishing methods, while providing the benefits of a hemp-based panel.
Water and Moisture
One of the major areas of development for Naichr is improved resistance to moisture.
Conventional wall and ceiling linings can be vulnerable when exposed to water from:
-
roof leaks
-
plumbing failures
-
storm damage
-
condensation
-
accidental water ingress
Naichr panels are designed so they do not readily soften or turn mushy when exposed to moisture.
That can provide an important durability advantage in both residential and commercial applications.
Mould and Indoor Environments
Moisture and mould are major concerns in Australian buildings.
No building product should be treated as a substitute for proper ventilation, waterproofing, drainage and maintenance.
However, selecting materials that are more resistant to moisture damage can form part of a healthier building strategy.
Naichr is being developed for use in wall and ceiling systems focused on durability, moisture management and healthier indoor spaces.
Termites and Rot
Traditional timber-based products can be vulnerable to termites, while many other natural materials can deteriorate when repeatedly exposed to moisture.
Naichr panels are designed to resist termite attack and rot, helping support a longer service life.
Australian Grown. Australian Manufactured.
One of the most important parts of the Naichr story is where the material comes from and where the products are intended to be made.
Naichr products are being developed around Australian-grown hemp and Australian manufacturing.
That provides an opportunity to:
-
support Australian farmers
-
create local manufacturing jobs
-
strengthen domestic supply chains
-
reduce reliance on imported finished building products
-
develop products suited to Australian construction conditions
-
grow a new natural-fibre building-products industry
Australia has the land, agricultural capability, construction knowledge and manufacturing skills to develop more building products locally.
Naichr is part of that opportunity.
Hemp Board Panels for Australian Construction
Searches for terms such as hemp board panels, hemp wall panels and hemp ceiling panels are increasing as architects, builders and homeowners look for alternatives to conventional materials.
Naichr is being developed specifically for this emerging market.
Potential applications include:
-
internal wall linings
-
ceiling linings
-
residential construction
-
commercial interiors
-
renovations
-
sustainable developments​
More Than One Product
Naichr is not being developed as a single isolated panel.
It forms part of a broader range of hemp-based construction products being developed for the Australian building industry.
The objective is simple:
Replace more conventional building products with practical, durable natural-fibre alternatives.
Not products that require builders to completely change the way they work.
Products designed to be realistic replacements for materials already used every day.
Why This Matters
Sustainable construction will only become mainstream when sustainable products are also practical.
They need to be:
Easy to specify.
Easy to transport.
Easy to install.
Durable.
Competitive.
Available at scale.
Suitable for modern construction.
That is what Naichr is being developed to achieve.
Hemp Board Panels Australia
Naichr represents a new direction for Australian wall and ceiling linings.
A hemp-based panel designed around durability, natural materials, practical construction and Australian manufacturing.
The building industry has relied on the same materials for a long time.
Perhaps it is time to ask:
What should come next?
Australian Grown. Australian Manufactured. Built Naturally.

WHAT ARE VOCs — AND WHY DO THEY MATTER IN YOUR HOME?
WHAT ARE VOCs — AND WHY DO THEY MATTER IN YOUR HOME?
When choosing building materials, most people look at strength, appearance, price and durability.
But there is another question worth asking:
What is this product releasing into the air inside the building?
VOCs — Volatile Organic Compounds — are chemicals that can be released into the air from some building products, finishes, adhesives, paints, sealants, furnishings and manufactured materials.
Some VOCs may only be noticeable as an odour. Others can contribute to poor indoor air quality, particularly when several emitting products are used together in a tightly sealed building with limited ventilation.
​
WHERE CAN VOCs COME FROM?
Depending on their formulation, VOC emissions may come from products such as:
• Paints and coatings
• Adhesives and sealants
• Manufactured boards
• Flooring products
• Cabinetry and furniture
• Synthetic finishes
• Cleaning products
• Some insulation and lining systems
This doesn't mean every manufactured building product is unsafe.
It means the materials selected for an indoor environment deserve consideration beyond simply how they look when the building is finished.
​
WHY INDOOR AIR QUALITY MATTERS
Modern buildings are becoming increasingly airtight to improve energy efficiency.
That can be a very good thing — but it also means ventilation and material selection become increasingly important.
If indoor materials release unwanted compounds, those emissions can remain within the occupied space unless the building has adequate ventilation and air exchange.
That is why architects, builders and homeowners are increasingly considering low-emission and natural-material building systems.
​
NATURAL DOESN'T AUTOMATICALLY MEAN ZERO VOC
This is important.
A product being natural or bio-based does not automatically prove that it has zero VOC emissions.
Binders, coatings, adhesives and finishes all need to be considered as part of the complete product.
Where a manufacturer makes a specific low-VOC, zero-VOC or emissions claim, it should ideally be supported by appropriate testing.
​
WHY KOSP IS FOCUSED ON NATURAL BUILDING SYSTEMS
KOSP's approach is to develop and supply building systems that make greater use of natural and bio-based materials.
These include:
• Naichr hemp-based building panels
• IsoHemp hemp blocks
• Gramitherm natural insulation
• Clay building products
• Lime and natural renders
Naichr wall and ceiling panels are being developed predominantly from hemp shiv fibre and bio-based binders, with the objective of creating practical natural-fibre alternatives to conventional lining products.
As development and testing continue, specific performance and emissions claims should be based on verified test results rather than assumptions.
​
HEALTHIER BUILDINGS NEED A COMPLETE APPROACH
Healthy indoor environments don't come from one product alone.
They come from combining:
Thoughtful material selection.
Ventilation.
Good design.
And products selected with indoor air quality in mind.
At KOSP, we believe sustainable construction should consider not only the energy used by a building — but also the environment we create for the people living and working inside it.

36 dB Noise Reduction
36 dB Noise Reduction — Naichr Natural-Fibre Acoustic Panels
Noise is becoming a bigger issue in modern living.
Traffic, trucks, machinery, construction, commercial activity and increasingly dense residential areas can all affect the comfort of homes, workplaces and outdoor spaces.
That is why acoustic performance needs to be considered as part of good building design.
KOSP is developing Naichr natural-fibre acoustic panels as a practical alternative to more conventional noise-control systems.
Our current Naichr acoustic panel system has achieved approximately 36 dB sound reduction, demonstrating the potential of hemp-based materials in applications where noise control is important.
What does 36 dB reduction mean?
A reduction of 36 dB represents a substantial change in sound transmission through a barrier system.
In practical terms, reducing unwanted noise by this level can make a noticeable difference to the comfort of spaces affected by road traffic, machinery or other external noise sources.
Acoustic performance will always depend on the complete system, including panel thickness, installation method, joints, supports, overall wall construction and the type of noise being controlled.
For that reason, Naichr acoustic panels should be considered as part of a complete acoustic barrier system rather than simply as an individual sheet product.
​
Where can Naichr acoustic panels be used?
Potential applications include:
-
boundary walls
-
residential developments
-
roadside noise barriers
-
commercial projects
-
workshops
-
industrial areas
-
plant and machinery enclosures
-
internal acoustic separation
-
infrastructure projects
-
other noise-sensitive environments
-
​
Natural-fibre construction with acoustic performance
Naichr acoustic panels are being developed using predominantly hemp-based natural-fibre materials.
The objective is to combine practical acoustic performance with a more sustainable material approach.
Rather than relying only on traditional steel, concrete or mineral-based acoustic systems, Naichr is being developed to provide another option for projects looking for both performance and lower-impact materials.
​
Designed for durability
Acoustic barriers can be exposed to demanding conditions, particularly when used outdoors.
Naichr panels are being developed with durability, moisture resistance and long service life in mind.
The aim is to create an acoustic product that is not only effective at reducing noise, but also practical for long-term use in Australian conditions.
​
Australian-developed natural-fibre building products
The Naichr acoustic panel forms part of a broader range of natural-fibre construction products being developed by KOSP.
The long-term objective is to replace more conventional building products with practical alternatives based around Australian-grown fibres and Australian manufacturing.
This has the potential to support:
-
Australian manufacturing
-
local jobs
-
Australian agriculture
-
stronger domestic supply chains
-
more sustainable construction
-
future export opportunities
-
​
A quieter future, built naturally
Good acoustic design is about more than blocking sound.
It is about creating better places to live, work and spend time.
Naichr natural-fibre acoustic panels are being developed to help provide that outcome while supporting a more sustainable approach to construction.
