Dura Cladding | Resist

Co-extruded composite timber cladding with a Class B fire rating

Dura Cladding Resist is made with up to 78% recycled content, is FSC® Certified and offers a natural wood cladding appearance with a 15 year warranty but without any of the maintenance headaches associated with traditional wood.

With safety at the forefront of Dura’s product innovation, Dura Cladding Resist complies with Building Regulations for buildings below 18 metres in height and achieves a fire rating specification of B-s2 d0 – in recognition of its low smoke volume and the absence of droplet production in the event of a fire.

In choosing the Dura Cladding Resist System you can be confident that you are selecting a composite timber cladding plank that has been rigorously tested and is designed for the real world. For more information on our range of tests, please consult our Technical Installation Manual.

Dura Cladding Resist comes in 6 different colours, now includes NEW SLIMLINE aluminium trims and can be complimented by Dura Deck.

Dura Cladding Resist (FR) Colours

Our Dura Cladding Resist planks are available in six great wood-look colours. Free samples are available on request so you can appreciate the stunning reversible surface finish for yourself. Please note that colours shown are representative only; actual colours may vary slightly. Whilst Dura Cladding Resist is designed to resist fading, you should expect a minimal amount of initial colour lightening as the product weathers after install, which typically occurs in the first 3 months.

Our manufacturing process results in a high level of colour consistency although some variation in colour may be apparent across boards from different production batches.

6 Reasons To Choose Dura Cladding Resist

Fire Performance

The UK’s first co-extruded composite timber cladding with Class B Fire Rating and tested in accordance with genuine install methodology, Dura Cladding Resist achieves superior fire resistance to any other co-extruded cladding on the market. Engineered to resist ignition of fire and tested to BS EN 13501 Class B s2 d0 to satisfy current fire legislation.

Fade Resistant

Unique outer armour protects against fade so that your cladding always looks like it did when it was new. With reversible planks for maximum versatility, you can choose from either a woodgrain or grooved appearance.

Stain Resistant

The revolutionary outer armour protects the cladding surface from common stains, such as tree sap, providing a low maintenance and long term weatherboard building cladding solution.

Resists Expansion

Dura Cladding Resist features a rate of expansion less than half of its competitors. This means the cladding looks great in all climates.

Easy Installation

An easy to install fire rated composite cladding solution with simplified, low profile aluminium trims. Features pre-drilled slotted fixing holes in the cladding planks and hassle-free fixing screws.

Environmentally Friendly

Dura Cladding Resist is FSC® certified, meaning its kinder to the environment thanks to its recycled content, long-life cycle and recyclability.

As the UK’s first co-extruded composite timber cladding rated to a Class B fire rating and tested in accordance with genuine install methodology, Dura Cladding Resist achieves superior fire resistance to any other co-extruded cladding on the market.

British Standards and European codes use different grading systems to class fire performance of materials, resulting in confusion for the industry. Dura Cladding Resist is designed to cut through the noise. Some competitors may reach Class B when tested specifically with certain fire rated barriers but fail when following their own install guide (due to lack of airflow).

Our test was conducted with a void to replicate a genuine site install, rather than being fixed to a fire rated barrier. Dura Cladding Resist features a co-extruded 360° outer armour which protects the core of the plank, increasing its defensive properties against fire.

Customers can have confidence that Dura Cladding Resist has been certified and tested by a UKAS accredited body, satisfying current fire legislation; with testing carried out in an environment to closely resemble that of an actual installation for the avoidance of doubt.

Understanding European classification (BS EN 13501): Dura Cladding Resist – B s2 d0

The standard includes Dura Cladding Resist seven classification levels, from A1 to F, with A1 representing the highest level of performance and F representing the lowest level. Dura Cladding Resist achieves Class B – the best on the market.

The ‘s’ part relates to total smoke propagation, during the first ten minutes of exposure. These determine a ‘smoke’ index which affects visibility in case of a fire. The lower the number the less smoke propagation.

The ‘d’ part relates to ‘flaming droplets and particles’ during the first 10 minutes of exposure. The index determines the level of risk from burning droplets and consequently potential fire spread. d0 = none  d1 = some  d2 = quite a lot

When considering the suitability of cladding materials for your project it is critical to first understand the latest regulatory guidance issued by HM Government’s Ministry of Housing, Communities & Local Government.

For buildings below 18 metres including dwelling houses or domestic properties, a minimum fire rating specification is required by law. This applies to both protected areas such as stairwells or other refuge points, and unprotected areas such as property boundaries or the boundaries with adjacent buildings.

The standard to which external cladding materials must comply is known as EN BS 13501 and is the latest iteration of fire standards and improves on previous tests such as BS476 which were limited in both scope and classification. Current guidance regarding dwelling houses and other buildings below 18 metres require a minimum classification of Class B-s3 d2.

Dura Cladding Resist has successfully achieved the superior classification of B-s2 d0 – in recognition of its lower smoke volume and the absence of droplet production in the event of a fire. These attributes, combined with its limited contribution to flame spread mean that should the building be under attack from fire, firefighters’ visibility would be less impeded, leaving them able to expediently deal with extinguishing the fire. In addition, the unique composition of Dura Cladding also prevents spontaneous re-ignition when the source of the flame is removed – further enhancing its safety properties.

Please note that it is the responsibility of the client and contractor to ensure that your planned design is fully compliant with Building Regulations. For further guidance on fire safety, please refer to the latest government documentation which can be found here.
