Haven™ Hollow Close Composite Fence by Green Plank is a modern fencing system created for homeowners, architects, landscapers and professional projects looking for the warmth of wood with the practical advantages of Wood Plastic Composite technology.
Designed as a close-board Composite Fence, Haven™ can create a strong sense of privacy around gardens, terraces, patios, swimming-pool surroundings and residential or commercial outdoor spaces. For projects where privacy needs to be combined with a more open architectural character, the fencing system can also be designed with glass sections.
The Haven™ hollow fence profile measures 161 × 20 mm and weighs approximately 2.10 kg per linear metre. Its engineered hollow construction reduces unnecessary weight while maintaining the substantial appearance expected from a premium Composite Fence.
Depending on the current product specification, Haven™ contains approximately 55–60% beech hardwood fibre, selected European-sourced recycled HDPE (rHDPE) and functional additives sourced from Europe and/or the USA.
The complete fencing concept can be combined with aluminium or galvanized-steel fence posts manufactured in Europe, creating a practical system for modern residential and professional landscaping projects.
Privacy is one of the main reasons homeowners choose a fence. Haven™ has therefore been designed as a close Composite Fence system that can create a visually continuous barrier between a private garden and the surrounding environment.
Without glass sections, Haven™ can be configured as a full privacy fence, subject to the selected system configuration and installation requirements. This makes it particularly suitable for gardens, terraces, property boundaries, outdoor dining areas and spaces where greater visual separation is desired.
The result is a clean, contemporary fence without the regular painting and oiling normally associated with traditional timber fencing.
Not every part of a garden needs complete visual screening. Haven™ offers designers greater flexibility by allowing compatible glass elements to be incorporated into selected fence configurations.
Combining composite boards with glass can create an attractive balance between privacy and openness. Lower or selected sections can use the Haven™ Composite Fence boards, while glass elements can help preserve light, views and a more spacious feeling.
This can be particularly attractive for terraces, patios, contemporary villas and properties where the landscape or surrounding view is an important part of the architecture.
Glass specification, thickness, safety classification, fixing method and structural design should always be selected according to the relevant project requirements and local building regulations.
Haven™ contains approximately 55–60% beech hardwood fibre, depending on the current product specification.
The wood fibre contributes to the profile's stiffness, natural character and warm wood-inspired appearance. It is combined with recycled HDPE to create a balanced Wood Plastic Composite formulation designed for long-term outdoor use.
A high-quality Composite Fence is not determined simply by maximizing the percentage of wood fibre. The quality and consistency of the polymer, functional additives, fibre preparation, profile engineering and manufacturing process all contribute to the performance of the finished product.
The polymer component of Haven™ uses selected European-sourced recycled HDPE (rHDPE).
When correctly formulated and processed, HDPE forms the polymer matrix surrounding the wood fibres and contributes to the profile's structural integrity, moisture resistance and suitability for outdoor applications.
Using recycled HDPE also gives existing polymer material a new, long-life application rather than relying exclusively on virgin resources.
Modern Wood Plastic Composite technology requires more than wood fibre and polymer. Haven™ therefore uses selected functional additives sourced from Europe and/or the USA.
Depending on the formulation, these can support processing, UV stability, oxidation resistance, pigmentation and the interaction between the wood fibre and polymer matrix.
Material transparency matters increasingly to architects, professional buyers, distributors and environmentally conscious homeowners.
Haven™ therefore offers 100% traceability of its declared raw materials, providing greater transparency around the beech fibre, recycled HDPE and functional additives used in the product.
For professional buyers, this makes it easier to understand what is actually inside the Composite Fence rather than making a purchasing decision based only on appearance and price.
The Haven™ fence board has a profile dimension of 161 × 20 mm and weighs approximately 2.10 kg per linear metre.
The engineered hollow construction is designed to reduce unnecessary material and profile weight while retaining the strong visual character required for a modern privacy fence.
The lower weight also makes individual boards easier to handle during transport and installation compared with heavier solid alternatives.
A fencing system depends on more than the boards themselves. Haven™ can therefore be combined with aluminium or galvanized-steel fence posts manufactured in Europe.
The post system provides the structural framework for the fence while the composite boards create the visual surface and privacy.
Depending on the project, aluminium can provide a clean contemporary appearance, while galvanized steel can be selected where the particular system or structural design calls for it.
Post spacing, foundations, anchoring and structural requirements should always be determined according to fence height, wind exposure, ground conditions, system configuration and current Green Plank installation documentation.
A fence is a major visual element of a property, so colour selection can have a significant influence on the overall architectural character.
Haven™ is available in 7 standard colours, providing homeowners, designers and architects with the flexibility to coordinate the Composite Fence with decking, cladding, façades, garden furniture and other exterior elements.
Whether the project calls for a contemporary grey tone, a warmer wood-inspired appearance or a darker architectural finish, the Haven™ colour collection provides options for different styles of homes and landscapes.
Haven™ is designed to have the warm visual character associated with wood. Like many wood-fibre composite products, the surface may undergo a small and natural colour evolution during approximately the first six months after outdoor exposure.
This initial settling of the colour is part of the natural weathering behaviour of a wood-containing composite surface and should not automatically be interpreted as a product defect.
The exact appearance and degree of colour evolution can vary depending on colour, sunlight, orientation, weather exposure and local environmental conditions.
Outdoor fencing in Northern Europe can face demanding conditions throughout the year – rain, moisture, snow, frost, summer sunshine and repeated temperature changes.
Haven™ has been developed with these conditions in mind. Its combination of beech fibre, recycled HDPE, functional additives and engineered hollow profile is intended for long-term outdoor use when the Composite Fence is correctly designed, installed and maintained.
Correct foundations, post installation, drainage, expansion allowances and installation details remain essential to achieving reliable long-term performance.
One of the practical advantages of Haven™ is its low-maintenance character.
Unlike traditional timber fencing, the Composite Fence does not normally require regular painting, staining or oiling to maintain its everyday appearance.
Routine cleaning can generally be carried out using water, a suitable mild cleaning product and a soft brush when necessary.
This makes Haven™ particularly attractive for homeowners, housing developments, hospitality projects and other applications where reducing long-term maintenance work is important.
Haven™ combines an engineered hollow construction with European-sourced recycled HDPE and traceable declared raw materials.
The system is developed with a focus on efficient material use, long service life and a lower CO₂ footprint. Any specific or comparative carbon-footprint claim should be supported by the applicable product, LCA or environmental documentation.
A fence should be considered a long-term part of the property rather than a short-term decorative addition.
Haven™ is therefore developed as a long-life Composite Fence system. Selected Haven™ products and applications may be covered by a warranty of up to 30 years, subject to the applicable Green Plank warranty terms, intended application and correct installation.

Haven™ gives homeowners and designers the freedom to decide how private – or how open – an outdoor space should feel.
For maximum screening, Haven™ can be configured as a close Composite Fence with a visually continuous board arrangement. For more open spaces, compatible glass elements can be introduced to bring additional light and visual connection to the surrounding landscape.
This flexibility makes Haven™ suitable for contemporary homes, garden boundaries, terraces, patios, residential developments, hospitality environments and architectural landscape projects.
The combination of 7 standard colours, European-made aluminium or galvanized-steel posts and optional glass elements gives architects and designers the opportunity to treat the fence as an integrated part of the building and landscape rather than simply as a property boundary.
Haven™ combines approximately 55–60% beech hardwood fibre, European-sourced recycled HDPE, traceable declared raw materials, an engineered hollow profile and European-made metal posts in a versatile fencing concept.
The result is a modern Composite Fence designed to deliver privacy, architectural flexibility, easy maintenance and a warm wood-inspired appearance for long-term outdoor spaces.
