Designer profile
WOOD ELEMENTS collective features include; a straight-line edging process to ensure the cladding is machined to a fine tolerance; relief grooves which are designed to take the stress out of the cladding; a specially designed ridge locater connects with the overlap line controlling the expansion allowance for any timber movement.

Finish Options
Hurford's offer 3 finish options in Wood Elements:

• Dressed Face
• Sawn Brushed Face
• Shou Sugi Ban (Charred)

Designer Trims
WOOD ELEMENTS trims provide a streamline finish and play an integral part in ensuring a water tight finish. All aluminium trims are factory fitted with waterproof gaskets* , designed to decrease the on-site sealing process, and delivery of loose materials. WOOD ELEMENTS trims are available in a black powder coated chromate treated aluminium.

Design Elements & Fixing
Extreme care has been taken in all aspects of WOOD ELEMENTS Refined Architectural Hardwood Cladding. From the environment to milling and drying, profile and trim design and species selection. Each element plays an important role in the performance of the cladding system.

Double Dried Technology
All the timber used to manufacture WOOD ELEMENTS is air dried for up to 12 months to bring the moisture content down to “fibre” saturation. From this point the timber is kiln dried using double drying technology, developed by Hurfords to ensure significant added stability. This produces a finished product with a very narrow moisture variation.

Straight Line Dressed
When timber is milled and dried it builds stress and force, which translates into spring and bow. Steps can be taken during this process to minimise this. Hurfords uses a process to straighten the boards post drying to ensure the boards are straight and stay straight. This ensures that WOOD ELEMENTS can be easily installed and all shadowlines remain as they have been designed – straight.

Automatic Spacing System
The Automatic Spacing System allows expansion to be placed between the boards, which is automatic and doesn’t require any special tools or spacers to get right. The specially designed ridge locator controls the expansion allowance. This unique design feature takes out any pressure caused if the boards expand due to absorption of moisture.

End Matched
Utilising a specially developed end match system for external use, WOOD ELEMENTS end-match profile has a micro bevel edge designed to encourage water to drain away from the join. End matching the product means the boards can be fixed mid cavity batten, eliminating the need to dock and create volumes of waste, saving a minimum of 10% of the product that previously would have been thrown away. Not only does this save costs, it’s a better for our environment with less resource being used.

WOOD ELEMENTS is a cladding that has been designed with concealed fixing in mind. For fixing, Hurford’s recommend screwing along the pre machined “screw location” line which enables the board to slip over the secured row quickly and easily, creating a clear face finish.

Design Points
WOOD ELEMENTS is a natural product, a renewable resource, providing an environmental advantage over common building materials. Timber will only perform within the limits of its natural properties, when specifying, it’s critical that the characteristics and properties of the timber are considered and determine how they will respond to the environment they are placed in.

Timber Movement
Timber is a hygroscopic product, which means that it will absorb or lose moisture depending on the environment it is placed in. When timber is placed in a high humidity (moist) environment it absorbs moisture and expands, oppositely when timber is placed in a low humidity (dry) environment it sheds moisture and shrinks. 

Although all Wood Elements products are kiln dried it is important that local conditions are taken into account when planning. Consider the level of sun exposure, wind, rainfall and humidity in the area. Identify any possibilities of extreme conditions and alter the designs to suit. Allowances made at design stage can avoid potential problems later on. Our cladding profiles allow for 2.5mm expansion and 7mm contraction.

Maintenance for Dressed Face & Sawn Brushed Face

Considerations at design stage regarding the accessibility, positioning and finish should be discussed between the client and builder. The expected outcome will determine the level of maintenance required. 

The extent of maintenance can depend on two main points; 

1. The type of finish that’s applied - All external coatings need to be applied and maintained in accordance with the manufacturer’s recommendations. 
2. The amount of additional protection the façade has from the weather including the degree of sun exposure - Extra protection can include wide eaves, soffits, avoiding water traps, utilise balconies/ covered space or even glass panelling installed in front of the cladding. 

For a minimal maintenance option, consider allowing WOOD ELEMENTS to weather naturally. With this you should expect increased checking, fading and greying of the timber cladding. Greying affects the surface of the timber, if a change in appearance is decided WOOD ELEMENTS can be rejuvenated and finished to the new desired effect. 

Please note: An extensive process may be required to prepare the surface for rejuvenating and finishing, depending on the degree in breakdown of the surface fibres. WOOD ELEMENTS requires no structural maintenance once installed correctly.

Maintenance for Shou Sugi Ban (Charred)

It is well known that any timber left uncoated and exposed to direct or indirect sunlight will inevitably weather and grey off. Hurford’s Shou Sugi Ban Refined Architectural Cladding is no exception. 

Shou Sugi Ban is supplied pre-oiled with Feast Watson Timber and Deck Stain, Black Japan to assist in the protection from aging and colour change. During installation it is required you coat any sawn cut exposed ends with Feast Watson Timber and Deck Stain, Black Japan. Once Shou Sugi Ban Refined Architectural Cladding is installed, apply a second coat of Feast Watson Timber and Deck Stain, Black Japan to hide any imperfections that may occur during installation. 

Periodic maintenance, including reapplying a fresh coat of Feast Watson Timber and Deck Stain, Black Japan is required to maintain the dark burnt texture of the product. Leaving the product unmaintained or uncoated will lead to the dark Shou Sugi Ban to naturally fade and age, changing its appearance. This change in appearance will not affect the performance of the product. 

All of Wood Elements Cladding is 100% PEFC Certified.
