Ultra Deck has an attractive natural appearance and is made from hard-wearing composite timber (also known as WPC).

WPC is the ideal alternative to traditional wood which requires staining or painting to maintain its original appearance. Further, Ultra Deck features a very low absorption rate which means that its strength is retained over its life cycle.

Our unique Composite Timber formula produces an extremely durable decking that is environmentally friendly, easy to install and requires minimal maintenance. Ultra Deck is available in Eco or Resist ranges to suit various budgets and project requirements.

Our narrower boards (Eco 146, Resist 150) have a more traditional appearance and closely resemble natural wood planks.

However, if your priority is maximising the speed of installation or span capability then our double width board (Eco 295) may be more suitable. All Ultra Deck composite timber boards are reversible to allow the installer to choose from two attractive finishes.

Ultra Deck boards are reversible, with a 10 year warranty, and suit most pontoon structures.

What are the differences in performance between Dura Deck Eco and Resist

What Are Composites?

Composite materials are products made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with different characteristics to those of the individual components.

What Are Wood Plastic Composites?

Wood-plastic composites (WPC) are composites made of wood fibre/wood flour and thermoplastic materials.

Why Choose Ultra Deck?

Ultra Deck is manufactured from a unique combination of wood and plastic and our highly developed unique composition combines the traditional appearance of timber with the durability of an engineered composite.

Made from an innovative blend of up to 87% recycled hardwood and plastics, Ultra Deck Composite Timber helps to conserve the earth’s resources whilst reducing the amount of waste sent to landfill.

Ultra Deck’s Unique Composition

Using state-of-the-art product design, proprietary product formulas and precise manufacturing techniques, Dura has been able to achieve an additional 60% extra strength versus similar designs from competitors. This added strength helps prevent long term failure caused by permanent deflection (otherwise known as ‘sag’). Our unique design enables the same span to be used whether you plan to install Ultra Deck residentially or commercially.

Load Performance Explained

We take our warranty seriously and as such, our deck boards have been designed with a unique ‘Vortex Void’ structure to optimise their strength over the warranty period in all conditions, and for all applications.

4S Slider Explained

The 4s rubber slider test imitates the heel of a shoe or foot to determine the level of slip resistance. The 4s slider test method is specially designed to replicate everyday footwear across a surface. The four S’s stands for: STANDARD SHOE SOLE SIMULATOR

The 4s slider test should not be confused with the pendulum 5s slider or TRL (Transport Road Laboratory) test, which is designed for testing slip resistance on a roading surface. The results gained from a 5s slider/TRL test are significantly higher than the 4s slider test. The 4s slider test can be relied upon in a court of law where a personal injury claim may have been made. This test measures the floors slip resistance values against the recommended health and safety minimum value of ‘36’ and proves to insurance companies, slip accident claimants (genuine or fraudulent), and personal injury lawyers, that a safe floor environment has been provided.

Eco 146

Designed and tested to pass BS EN 13501 Class Cfl-s1 for ultimate peace of mind. This range exceeds the performance of almost all of its direct competitors.

Resist 150

Engineered to resist the ignition of fire the Resist range has been rigorously tested for consumer piece of mind and confidence. The co-extruded 360° outer armour protects the core, increasing its defensive properties against fire. Resist achieves Bfl-s1 according to BS EN 13501, giving you confidence this range is the best in class performer.

Eco 146

Latest technology deployed to ensure the colour fade over time is minor, providing a deck that always looks like new.

Resist 150

Protected by the outer armour, the Resist range is even more colour stable than Eco and other co-extruded WPC decking boards on the market.
