Firstly, calculate how many square metres your project will require, then add between 5 – 10% onto the figure calculated. This allows for wastage or on-site damage to the timber. It is worth noting that the inconvenience and extra costs incurred of not ordering enough timber can be quite significant.
The cladding is usually fitted once your windows have been fixed in, as this allows the ingo dimensions to be determined. However, the ideal stage to fix the cladding can vary depending on the type of construction - advice on this should be provided by your project architect.
To ensure that the correct species and profile of Russwood timber is purchased for your project, please speak to our technical team for advice on completing the NBS H21. This will ensure that the product is correctly specified, giving you the look that you desire.
On bearers, with the top of the pack covered, left open at the sides in order for air to circulate, and out of direct sunlight. Please ensure that the straps and stickers (smaller pieces of timber going cross ways at certain layers) are still in place until you're ready to use the cladding - this ensures adequate airflow throughout the cladding.
We always recommend that cladding is installed as soon as possible after delivery, ideally within two weeks. Even if suitable storage conditions are ensured, variables such as species, external environment and climate can have an effect on your cladding if stored for too long a period. Advice can be given on your choice of cladding when ordering if storage is necessary.
Generally 600mm centres will be the recommended distance, but this distance can on occasion be altered based on the thickness of cladding board or location of your project.
Pre-drilling may be required when nail fixing certain species. Our L-GoFix® screw does not require pre-drilling (except when using hardwoods) due to it's unique design characteristics, saving time on-site.
Yes. A screw generally gives better results in that more care is taken in positioning and finishing the screw head flush with the timber surface. As screws do not bend when they hit a knot in the fixing batton, from our experience, it takes the same amount of time to fix a facade with screws as it does with nails.
Yes, providing it is the appropriate stainless steel nail. It is also important that the nail is not overdriven into the board, as this will produce a “bullet-hole” effect which may compromise the durability of the board. The nail must be finished flush to the timber to prevent water ingress at the point of fixing which can severely shorten the longevity of the facade.
All fixings must be stainless steel in order to eliminate corrosive leaching which can be very unsightly. Our recommended fixing systems are detailed on our fixings page.
Unsightly iron rust stains will occur when non-stainless steel nails used to fix naturally durable timbers.
A solution of oxalic acid is ideal for removing stains after they occur, but prevention is infinitely preferable.
We would always recommend using a mechanical fixing method, as seen on our fixings page.
Secret fixing has evolved as a design solution, and should only be used with the relevant profiles, which are available only in certain compatible timbers. The main difference between face and secret fixing is an aesthetic one. However, secret-fixing with FassadenClip® will increase the longevity of the facade by improving ventilation.
Yes there is. It is important to ensure that, if a T&G profile is used, the groove faces down to avoid holding water. All of our profiled boards have a stress groove on the rear of the board, and will be printed to ensure that the front and back are not mixed up. In the non-profiled timber cladding, for board on board, any sapwood present (the lighter wood) MUST be placed at the rear of the cladding to maintain the natural durability of the wood.
There are numerous options for detailing corner and window/door reveals. It is important to choose the right one in order to ensure timber longevity, performance and the aesthetics. This is generally decided at the design stage as the detailing you choose must permit rapid drying of the end grain of your boards.
A moisture gap (or cavity) behind the cladding is the single most important factor in the success of the cladding installation, and a 20mm gap between the cladding and wall is the minimum that we would advise. The purpose of this cavity is to ensure air circulation behind the boards. This prevents a build-up of moisture from occurring which, if allowed, would compromise the durability of your cladding and cause unsightly staining of the timber.
No, the timber cladding we supply is inherently durable, meaning no protective coating is necessary if detailed and installed correctly. The decision to coat timber cladding is purely an aesthetic one.
Coatings can be applied onsite manually, weather permitting. We offer the option of vacuum coating, the benefits of which are described in full here. However, to summarise, this process will circumnavigate any need to wait for suitable weather conditions before application, and will provide a coated board with a smoother, longer lasting and more consistent finish.
It depends on various factors such as weather patterns, situation, location and aspect. As a general rule the more exposed to wind, sun and rain the cladding is, the quicker it will weather. Generally, weathering on exposed cladding will become noticeable within six months. For further information, go to our weathering page.
To see some examples of how cladding samples at Russwood have weathered over time, please have a look at our cladding gallery.
Yes. SiOO:X is a patented silicon technology which is a major step forward in offering timber with a consistently weathered appearance. From our factory coating facility we can produce pre-coated cladding which is ready to be fixed as soon as it arrives on-site, regardless of weather conditions. Alternatively, for on-site brush application we supply SiOO:X in 3, 5 or 25 litre tubs as well as 250ml sample pots, all of which can be purchased through our online shop.

This depends entirely on the nail. The appearance of stainless steel will remain constant, whereas galvanised and copper nails will change colour over time.
There are no absolute rules, as in both instances the requirements will vary according to external parameters. These parameters include, but are not limited to, the location of the project, how the cladding has been fitted and the type of coating used. Vacuum coated cladding (VCC) is proven to last longer than onsite painted cladding owing to the regulated consistency of the coating achieving greater than a 90 micron (dry coating) thickness - see independently commissioned test results here. We would advise that monitoring of your coating is an ongoing process, and that preventative measures are taken promptly as this will prolong the life of the existing coating.
Prices displayed on our on-line shop are all inclusive of VAT. The VAT element of personal quotations will be itemised.
Lead times for delivery can vary from a matter of days for stock items, to a few weeks for custom profiles and vacuum coated cladding orders. Please enquire about current stock levels and/or lead times before ordering to ensure your cladding arrives at the appropriate stage of your project.
We organise our own delivery, using a hi-ab off-loading service. On occasion we use an approved external haulier/courier who will always require off-loading assistance at the point of delivery. We advise on this whilst organising delivery in each instance.
We deliver all over the UK. However, it should be noted that, although we do all we can to minimise cladding delivery costs, it is regrettably the case that for small orders the cost of delivery to the South of England can be disproportionately high.
It depends on the location but it is always best to have someone on-site to sign for the goods.
Generally your order will be polythene wrapped, strapped and offloaded by hi-ab within Scotland. If your delivery is in England, an off-load facility will need to be organised as delivery will be by external courier. This will be confirmed by our haulage department.
Delivery costs vary and are dependent on location.
We offer advice on our cladding products as standard to our customers. We are happy to write the NBS specification for your project. We can also advise on the fixing, fitting and detailing that your project requires – please enquire when placing your order.
FSC and PEFC sustainability certification and Class B certificates of conformity for fire retardancy can be provided on request. To provide certification for stress graded timber a request must be made prior to order/purchase.
