Vacuum Coated Cladding - Coloured Finish

Russwood’s vacuum coated cladding guarantees a consistent, high quality finish and optimal long term product performance.

Due to the increasing popularity of painted cladding, as an alternative to natural weathered timber, Russwood are now manufacturing vacuum coated cladding at our in-house state-of-the-art coating facility; the first of its kind in Scotland. By treating the timber under factory-controlled conditions we can guarantee that the application will be of a consistently high standard, and that the resulting end-product will offer enhanced aesthetic and durability properties as well as a reduced maintenance cycle.

Currently, many of our customers paint their cladding on-site but, as you can see from the following comparison table and independently commissioned test results, ordering cladding pre-coated brings a number of significant advantages.


  Russwood vacuum-coating On-site paint application
Paint type Primer and top coat are water-based and environmentally friendly Any paint can be used therefore the suitability and environmental credentials are not guaranteed
Primer type The primer (translucent only) contains fungicide to protect against blue stain On-site primer is unlikely to contain fungicide therefore the risk of blue stain is higher
Paint colours Any opaque RAL colour and a range of 48 translucent shades from Teknos, are available Any paint can be used therefore the suitability and environmental credentials are not guaranteed
Coating thickness 1 coat of biocidal primer (translucent only) and 2 top coats in a shade of your choice ensure that the wood is protected and the finish even on all sides Difficult to monitor the quantity and quality of primer and top coat used
Initial costs Russwood charge a set price, quoted upfront, for coated cladding; this includes all preparation, coating, drying, storage and delivery. Labour, painting equipment and scaffolding (if required) costs will be incurred, plus the potential cost of project delays due to adverse weather conditions should be taken into consideration.
Ongoing costs Vacuum-coated timber is more durable than on-site painted timber so maintenance costs are lower After the paint is applied it will require frequent re-application, at considerable cost
Finish & Durability
Weather conditions required for application Coating is applied under factory conditions, to timber which is dried to the optimum moisture content of 16-18% (+/- 2), so weather is irrelevant In order to avoid the adverse effects of excess moisture dry weather conditions are required for a number of days.
Sealing Boards are coated on all four sides Often, only the front face is coated, leaving the back and ends of the boards uncoated and therefore exposed to the elements
Resistance to elements Product is water-repellent, stain resistant and UV-protected Durability properties vary and are dependent on factors such as application conditions, on-site expertise and paint quality
Aesthetic properties Consistently applied vacuum coating guarantees a flawless finish Inconsistencies in application may lead to a less-than-perfect end-result
Maintenance required Although re-application will be required, the initial coating will last longer than if it was applied on-site Coating will require frequent re-application
Advice & Delivery
Time take from order to finished product Approximately four weeks After delivery, completion will be entirely dependent on weather conditions
Advice available Timber, detailing, profile and fixing advice is part of the standard Russwood service This will be dependent on the timber cladding experience of the on-site team

As you can see from the above, the benefits of vacuum coated cladding are manifold, not only for clients but also for architects, builders and other sub-contractors.  Russwood offer a selection of different timbers (Scotlarch®, Siberian Larch, Natural Cladding® Western Red Cedar and Accoya® wood), all of which can be vacuum coated for orders of more than 50m2

Weathering and durability performance testing

Russwood has conducted extensive trials in partnership with the Forest Products Research Institute at Edinburgh Napier University to compare the weathering and durability performance of our vacuum coated cladding against a brush coated alternative.

Three species were tested – Accoya®, ScotLarch® and Western Red Cedar.  As expected, the independent set of results confirmed the significant benefits of vacuum coated cladding. To view the full test report, click here.

Our vacuum coated cladding is available in any opaque RAL Colour – if you advise us of the RAL number, or specify this in the H21, then we will happily supply any of our cladding coated with this shade.  Alternatively, for a translucent finish in Scotlarch®, SILA®, Western Red Cedar and Natural Cladding®, we can supply 24 Teknos colours - to see the comprehensive range please take a look at the PDF below;

For architects, we may also be able to offer a Colour Matching Service – please call us to discuss use of this service for your project.


We are happy to provide samples of most species with a vacuum coated finish in a non-specific colour.  However, for samples of cladding coated with specific colours we will charge £35 + VAT per sample (this is because, due to the extensive range available, we do not hold stock of all colours and therefore must order in customised samples).

What our customers say about vacuum coated cladding

  • Bernard Planterose, North Woods Design

    “The vacuum coated Scotlarch® supplied for the project exceeded our expectations both in the beautiful subtlety of its translucency and the smooth consistency of its finish. Added to its local origins, its low embodied energy and the long-term fixation of carbon in its solid timber, it is harder to imagine a more environmentally sound cladding material at this time. Only time will tell in such an extreme environment, but we feel very confident that a combination of larch and factory applied coating will ensure an exceptionally long life for this cladding, given even a little regular maintenance, and we will certainly be using it again in the near future.”
