TerraTuff™ Capped Composite Decking

TerraTuff™ 360° Capped FortiShell – Premium Composite Decking for Nordic Conditions

Choosing a deck is not only about how it looks on installation day. For homeowners, architects, developers and professional buyers, the real value comes from how well it performs, how little maintenance it requires and how attractive it remains over many years.

TerraTuff™ 360° Capped FortiShell by Green Plank is premium Composite Decking developed for buyers who want the warmth and character of wood without making ongoing maintenance part of the ownership experience. It brings together natural aesthetics, long-term durability, material traceability, good slip resistance and extensive colour flexibility in one engineered decking system.

For professional buyers, TerraTuff™ offers more than an attractive surface. Its combination of traceable raw materials, European-made installation components, long service life, low maintenance requirements and project colour options makes it a strong choice for residential developments, hospitality projects and demanding architectural applications.

Designed with challenging Nordic conditions in mind, TerraTuff™ combines an engineered WPC core with advanced 360° FortiShell protection. Depending on the specific formulation, the core can contain up to approximately 70–75% beech hardwood fibre, combined with virgin HDPE (prime HDPE) or carefully selected European-sourced recycled HDPE (rHDPE), together with functional additives sourced from Europe or the USA.

The result is a durable, wood-inspired outdoor surface designed to deliver a balance of appearance, performance, easy ownership and long-term value.

Why Buyers Choose TerraTuff™

A premium terrace should continue to create value long after installation. TerraTuff™ is designed around the factors that matter when comparing decking solutions for long-term use:

• Natural wood-inspired appearance with a solid, premium feel
• 360° FortiShell protection around the profile
• Up to approximately 70–75% beech hardwood fibre
• 100% traceability of declared raw materials
• Virgin HDPE or selected European-sourced recycled HDPE
• Surface developed with a focus on good slip resistance
• Low-maintenance surface with no routine oiling, staining or painting normally required
• 7 standard colours and up to 32 project colours for qualifying orders
• Selected systems engineered for support spacing up to 600 mm c/c
• Colour-performance protection up to 25 years for applicable systems
• Warranty up to 50 years for selected products and applications

For homeowners, this means more time enjoying the terrace and less time maintaining it. For architects, it means greater design freedom. For developers and professional buyers, it means a product designed around durability, documentation and lifecycle value.

360° FortiShell Protection

One of the defining features of TerraTuff™ is its advanced 360° FortiShell technology. The protective outer layer surrounds the profile, creating an additional barrier between the WPC core and direct exposure to moisture, dirt, stains, UV radiation and everyday wear.

This technology is designed to improve long-term surface performance while preserving the natural character and refined appearance expected from a premium outdoor product.

TerraTuff™ is therefore well suited to residential terraces, premium housing developments, hotels, restaurants, roof terraces, pool areas and selected commercial or public outdoor environments.

Up to 70–75% Beech Hardwood Fibre

TerraTuff™ is based on a carefully balanced Wood Plastic Composite formulation. Depending on the product specification, the core can contain up to approximately 70–75% beech hardwood fibre.

The beech fibre contributes to the profile's rigidity, natural character and wood-like feel. It is combined with virgin HDPE or selected European recycled HDPE, depending on the particular formulation.

Functional additives sourced from Europe or the USA support properties such as UV stability, oxidation resistance, pigmentation, processing performance and effective bonding between the wood fibre and polymer matrix.

The overall performance comes from the balance between hardwood fibre, HDPE, functional additives, profile engineering and the protective FortiShell layer.

100% Traceability of Declared Raw Materials

For Green Plank, quality is also about transparency. TerraTuff™ therefore offers 100% traceability of its declared raw materials.

This gives architects, project developers, contractors, distributors, retailers and professional buyers greater transparency regarding the wood fibres, polymers and functional additives used in the product.

A Natural Feel Inspired by Premium Timber

TerraTuff™ is designed to provide the substantial and refined feel often associated with premium and tropical hardwoods while offering the practical advantages of modern WPC technology.

Its material composition, density and textured surface create a robust, natural character underfoot. At the same time, it requires significantly less routine maintenance than many conventional timber terraces.

The result is an attractive wood-inspired outdoor surface without the same recurring need for oiling, staining or painting.

Good Slip Resistance for Outdoor Living

Slip resistance is an important consideration for any outdoor terrace, particularly in regions where surfaces are regularly exposed to rain and moisture.

TerraTuff™ features a textured surface developed with a strong focus on good slip resistance under normal outdoor conditions.

This makes it suitable for residential terraces, hotels, restaurants, balconies, walkways and poolside environments where the surface may regularly become wet.

Where a project requires a specific slip-resistance classification or compliance with a particular standard, performance should be confirmed using current test documentation for the relevant TerraTuff™ profile.

Easy Installation with Concealed Fixings

TerraTuff™ is designed for straightforward installation using compatible plastic or steel clips and suitable screws.

The concealed fixing system minimises visible screw heads across the main deck surface, helping to create a clean, consistent and professional finish.

Clips and screws are manufactured in Europe and selected to work as part of the Green Plank installation system.

Developed with a Focus on a Lower CO₂ Footprint

TerraTuff™ has been developed with a focus on efficient material use, traceable raw materials and long service life. In versions incorporating European recycled HDPE, the reuse of polymer material can also contribute to more resource-efficient material utilisation.

Specific claims regarding a lower CO₂ footprint should be supported by applicable product, LCA or environmental documentation. A meaningful environmental assessment should consider the complete lifecycle, including raw materials, transportation, maintenance requirements and expected service life.

Engineered for Nordic Conditions

Nordic weather places significant demands on outdoor building materials. Rain, snow, frost, moisture, summer sunlight and repeated temperature changes can affect a terrace throughout the year.

TerraTuff™ has been developed with these conditions in mind. Its combination of an engineered WPC core and protective 360° FortiShell cap makes it particularly well suited to Scandinavian, Nordic and Northern European environments.

Long-Term Colour Performance – Up to 25 Years

The FortiShell surface is engineered with a focus on high UV resistance and long-term colour stability.

For applicable TerraTuff™ systems, colour-performance protection of up to 25 years may apply in accordance with the relevant product specification and applicable warranty or colour-performance terms.

As with all materials exposed to outdoor conditions, minor natural changes in shade may occur over time. These should be distinguished from excessive or abnormal colour loss.

7 Standard Colours – Up to 32 Colour Options

TerraTuff™ is available in 7 standard colours selected to complement contemporary Scandinavian and international architecture.

For qualifying projects and appropriate order volumes, the product can also be manufactured in up to 32 different colours.

This gives architects and designers greater freedom to coordinate the terrace with façades, windows, roofing, outdoor furniture, landscape design and the overall architectural concept.

Support Spacing Up to 600 mm c/c

Selected TerraTuff™ systems can be engineered for support spacing of up to 600 mm centre-to-centre (c/c), depending on profile, loading requirements, application, substructure and installation conditions.

A wider permissible support spacing can contribute to a more efficient substructure and simplified installation. The current Green Plank technical data sheet and installation instructions for the specific profile should always determine the final installation requirements.

Easy to Clean and Low Maintenance

TerraTuff™ is made for people who want to enjoy their outdoor space rather than spend unnecessary time maintaining it.

The protective FortiShell surface is easy to clean and maintain. Routine cleaning helps keep the deck looking attractive, while regular oiling, staining or painting is normally unnecessary.

Up to 50-Year Warranty

TerraTuff™ is designed as a long-term premium outdoor solution.

For selected products and applications, it may be offered with a warranty of up to 50 years, subject to correct installation, intended use and the applicable Green Plank warranty terms.
