SILVALarch™ Channel Profile
Hugely popular in contemporary architecture thanks to its combination of durability and style, SILVALarch™ channel cladding will add a sense of depth and texture wherever and however you use it.
Whether indoors or out, or installed horizontally or vertically, the tongue and groove joint makes for easy installation, and the bold shadow line of the channel profile adds an element of modernity to almost any façade.
Made From Only the Finest Siberian Larch
Produced from the highest quality Siberian Larch from the Irkutsk region of Russia, the slow growth of the trees in the region makes for a very tight grain, and relatively few, well-interspersed tight knots. SILVALarch™ is produced from consistently high-quality wood fibre that far exceeds the official industry 'GOST 26002-83' grading standards.
Kiln Dried to a Uniform Moisture Content
In kiln drying SILVALarch™ to a moisture content of 16-18% (+/-2%), the boards dry uniformly which not only makes them more dimensionally stable, but lets you immediately coat them and install with minimal acclimatisation on site. Find out about the benefits of kiln drying.

SILVALarch™ is graded numerous times at source and then again at Silva Timber during the production process.
SILVA AB is the highest grade (comparable sawn grade ‘Unsorted’) containing the largest amount of mostly clear timber.
Our most popular grade SILVA BC (comparable sawn grade ‘Sawfalling’) allows slightly more knots and other natural characteristics than AB.
SILVA C (comparable sawn grade ‘Fourths’) is an economical grade that includes more frequent knots and a greater number of larger knots.
Siberian Larch – the ‘Tree of Eternity’
Siberian Larch is a sustainable, old-growth timber that has been used in construction for centuries. Today it is used extensively throughout Europe, primarily for external applications such as cladding and decking, and for other uses including flooring, bridges and even Olympic velodrome tracks. Its remarkable qualities and unique performance characteristics have led to it being referred to as the 'Tree of Eternity'.

Delivery charges vary based on the products you have ordered, the location of your delivery, the value of your order and the delivery service you require.
For charges and services, please click here.
Our economy delivery service uses our own delivery vehicles and is available in selected postcode areas only. Orders are grouped with others within specific regions and scheduled accordingly. This allows us to provide a significantly lower delivery rate. We endeavour to despatch your order as quickly as possible, however the date can vary depending on other orders in your area, up to a maximum of 14 days. Feel free to contact our customer support team on T: 0151 541 5485 for an estimated delivery date prior to ordering.
If you require your order urgently we are able to deliver via an independent haulier within 5-7 working days (factory coated orders may take a little longer). Once your order has been placed online, a member of our customer support team will contact you by phone to arrange a convenient delivery day and discuss your requirements. Deliveries usually take place between Monday & Friday between 8am and 6pm.
Deliveries to Northern Ireland, Orkney Islands, Argyll & Bute, Isle of Wight, the Isle of Man and Shetland Islands use our specialist delivery service. Delivery charges are calculated by the number of pallet spaces taken up by the load.
A pallet space is 1.22 metres or part thereof. The number of pallet spaces taken is determined by the longest item on the order. For example, if you order 2.44 metre long deck boards you will be charged for 2 pallet spaces.
Deliveries using this service usually take place 3 - 5 days after we receive your order (factory coated orders may take a little longer). We will contact you by phone to arrange a convenient delivery day. Deliveries usually take place Monday to Friday between 8am and 6pm.
A Saturday delivery service is available on request and subject to availability (additional charges will apply). Please contact our customer support team on T: 0151 541 5485 for a quote.
Smaller items like screws or wood finish are delivered using a reliable express parcel service. Our standard leadtime for this service is 2-3 days. Next working day delivery is also available on smaller items ordered before 11am.
Although rare, an additional charge may be payable should the delivery company require to attempt more than two deliveries of the same order.
Deliveries are often made on large vehicles. Please let us know in advance if there are any access restrictions; for example narrow streets / farm tracks, parking restrictions, road works etc which may affect delivery. Failure to notify us, in advance, of any access restrictions may result in additional delivery charges and / or an inability to fulfil the delivery.
To keep delivery charges to a minimum, goods are manually offloaded from the delivery vehicle. Someone must be on-site to sign for the delivery and to assist with the offload. If your order contains large lengths of timber you may need additional people on hand to help. As with most companies delivering building materials, delivery obligation ends at the kerbside.
If you would prefer to arrange your own haulage or collect in person please let us know. Collection is from either our Widnes (Cheshire) or Harmondsworth (W. London) branch. We can schedule in your collection so that your goods are picked and packed in advance and our warehouse team can assist in loading your vehicle promptly.
As orders may need to be processed, picked and packed from multiple locations we are unfortunately unable to offer a 'Click & Collect' service.
Customers will be contacted to arrange a convenient date and time for collection.
What time will my delivery arrive?
We appreciate that you may be taking time off work so we suggest that you request a call either on the morning of the agreed delivery date or one hour before delivery - whatever suits. Just enter your request in the 'Special Instructions' box on the order page.

For smaller items such as screws, nails, wood care products and shingles that are in stock, we aim to have your order with you within a few working days, with a next day delivery service available to most UK regions. Due to the nature of our larger items, such as deck boards, cladding and fencing, our picking and delivery times can vary. Once your order is placed a member of our sales team will contact you to arrange a suitable and prompt date of delivery.
What happens with my order?
Once an order is placed, it is keyed into our CRM system and added to the schedule for the operations team to pick. Customers are contacted the day after their order is placed to arrange a convenient delivery date.
