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 or breathable 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.

Naichr Wall & Ceiling Boards
​
Naichr wall and ceiling boards are natural hemp-based internal lining boards designed for walls, ceilings and healthy interior building systems.
They provide an alternative to conventional internal lining materials and are suited to projects where natural materials, breathability, durability and sustainable construction are important.
Naichr boards can be used in:
Internal walls
Ceilings
Renovations
Healthy homes
Commercial interiors
Modular buildings
Breathable wall systems
The boards are designed to work with suitable framing, insulation, breathable coatings and natural finishing systems as part of a complete interior wall or ceiling solution.

Naichr Boundary Fencing Systems
Naichr boundary fencing systems are designed as modular post-and-panel fencing solutions for residential, rural and boundary applications. The system uses Naichr posts with female slots that allow panels or rails to slide neatly into position, creating a clean and consistent fence line.
​
Naichr fencing is suited to projects where durability, low maintenance, natural materials and long-term outdoor performance are important. Unlike conventional timber or metal fencing systems, Naichr posts are designed to resist rust, rot and termite damage, making them a practical option for Australian conditions.
​
The system can be used for boundary fencing, garden fencing, rural-style fencing, screening, privacy areas and outdoor feature fencing.

Breathable Wall & Ceiling Systems
​
Breathable wall and ceiling systems are designed to help manage moisture movement through a building assembly, rather than trapping moisture inside walls and ceilings.
​
Naichr wall and ceiling boards can form part of a natural internal lining system when used with suitable framing, insulation, breathable coatings and mineral or lime-based finishes.
​
This approach can support healthier indoor environments, improved moisture control and more sustainable building design when correctly specified for the project.

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.

​
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, breathable wall systems, 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.

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.
