The natural beauty and versatility of wood along with its environmental and practical benefits make timber a popular choice for external and internal cladding. It can be combined harmoniously with other materials such as glass, stone or steel and allows you to creatively design the exterior of your building. A wide choice of different cladding styles allows you to create just the visual effect and properties you are looking for. We can produce timber cladding from sustainable and locally sourced larch, Douglas fir and spruce.
Species and weathering
- Larch cladding :
The natural durability of larch out of doors makes this timber an excellent and cost-effective alternative to hardwood cladding. Resins in the wood create a high resistance to rot and decay. This is why it is generally used untreated, although it is also suitable for optional pressure treatment. A conservative estimate of its lifespan is 30-40 years but it can last up to double that time. We use our own larch for cladding whenever possible. The strong grain live knots in the wood add to the characterful look of larch cladding. The colour of larch timber ranges from orange to red-brown shades. As larch cladding weathers, it changes to a beautiful silver-grey and blends in with its natural surroundings. If however you want to conserve the original colour of the wood, we recommend the application of Osmo UV oil (see section below on weathering). Prices for our larch cladding start at £11.00 + VAT per m² for feather edged and waney edged boards.
- Treated and untreated spruce cladding :
Spruce is an inexpensive softwood alternative for external cladding. It is know as non-durable in external conditions and is usually pressure treated but there are cases of untreated spruce lasting over 80 years. A conservative estimate of it’s lifespan is 25-35 years but if applied right untreated spruce can be as durable as any other softwood. To extend its lifespan is important to ensure untreated spruce is not in contact with the ground, well detailed and ideally protected with an overhang.
The colour of spruce is a light yellow, treatment with preservatives adds a green tinge. The live grain and knots in the wood add to the characteristic look of spruce cladding.
- Weathering : When uncoated timber is exposed to the elements, it will weather to a silver-grey shade. This is a natural process and should not be confused with decay. As the main cause for weathering is the exposure to UV radiation from the sun, the process can be greatly slowed down by applying UV protection. This is why we would recommend the application of Osmo UV oil if you would like to retain the original colour of the timber. UV oil slows the rate of weathering by a factor 12 compared to uncoated timber. For more information see our range of Osmo Natural wood finishes.
Feather edged cladding Feather edged cladding is machined from a single long rectangular piece of wood which is cut at an angle to make two accurately tapered boards. This offers the advantage of cutting down on the amount of wood needed to cover the same area compared to non-feather edged cladding and it also sits tighter to the building. The downside is that the thinner tapered edge of the wood is slightly less durable. Feather edged boards typically taper from 25mm to 10mm, they are laid horizontally with a 15mm overlap for 150mm wide boards.
Waney edged cladding Waney edged cladding gives your building a stunning natural look. One edge retains the outside shape of the tree whereas the other edge is square cut. The width of the boards is usually between 150 and 200mm and the most common thickness is either 20 or 25mm.
Profiled cladding Our profiled cladding comes in various styles, some of which use overlapping boards, others Tongue & Groove boards. T&G boards have the advantage of speeding up the installation process. They counteract the natural shrinkage and swelling of the wood and help to wind proof the building. Overlapping boards also provide excellent weather proofing and allow for movement in the wood. The partial overlap of the boards allows for hidden fixing application. The horizontal boards of shiplap cladding create an attractive shadow effect, whereas loglap creates the visual effect of a log cabin. Our profiled cladding typically comes in two thicknesses: 20mm (ex 1’’) and 15mm (ex 3/4’’).
Parallelogram cladding This style of cladding creates a contemporary and elegant look. The distance between boards is variable. This allows for variation between the facades without compromising the overall coherence of the building. Parallelogram cladding can be installed horizontally and vertically.
Board on board cladding The vertical lines of board on board cladding create a striking yet classic look. Alternating top and bottom boards create a facade that is rich in contrast. The optical effect of board and board can be reinforced by varying the width of the boards.
- Board and batten cladding This cladding style uses wide boards spaced apart with a small gap which is covered with a narrow board or ‘batten’. There are no set board or batten widths so we can adapt to your requirements to create the effect you want. The vertical lines of alternating bottom board and batten create a striking yet classic look.
