Made from high quality Redwood Thermowood with a fine sawn finish, our Redwood Thermowood Cladding options are suitable for domestic, commercial and agricultural cladding projects. Thermally treated timber has undergone first a kiln drying process and afterwards a thermal treatment for up to 48 hours and 260 degrees celsius. This process modifies the cellular structure of the material and will prevent degradation via insect attack, rot, weathering etc for many decades. The process changes the colour of the timber to various shades of brown depending on material, our Scandinavian redwood fifths end up a nice light chocolate brown.

Made from high quality Nordic Pine with a fine sawn finish, our Painted Kiln Dried Nordic Pine Cladding options are suitable for domestic, commercial and agricultural cladding projects.

Our Green (Fresh Sawn) Oak Cladding is ideal for where you require an elegantly rustic finish to your cladding project as well as long lasting protection from the elements.

Freshly sawn on site, these boards contain varying in size sound knots, sometimes some colour variation, fissures and areas of tight/straight perfectly grained oak. With a 30%+ moisture content, as the oak acclimatises to the changing temperatures, your boards will expand and contract. All of these natural characteristics of freshly sawn oak are what gives our Character Grade Oak Cladding its classically natural rustic charm, making it one of our most popular cladding choices.

Air-dried (seasoned) Oak has been dried since the tree was felled, either by spending 3-5 years exposed to air or by accelerated drying inside a kiln. This process reduces the moisture content to approximately 20-30% compared to that of our other oak cladding, making it more stable than a fresh sawn cladding product and less prone to shrinkage.

Due to the higher grade of oak used, you will experience less sap, fewer/smaller knots and a tighter/straighter grain. Being a natural living product, you may also experience some colour variation and when in place, some natural movement as the timber adjusts to the changing seasons. These characteristics are to be expected and will give a beautiful natural distinctive appearance.

British Larch/Douglas Fir has striking colour variations from pinks, browns to creams depending on which part of the tree it is cut. There are some dark brown knots that can loosen as the wood dries, this occasionally results in resin patches that may ooze a little at first and sometimes during subsequent hot summers. If left untreated larch cladding fades to a silvery grey over a period of time and as nature does its work.

As well as being a very strong and very hard-wearing wood, due to its super high resin content, English Larch can prove to be twice as durable as common pine. Highly suitable for cladding buildings in a traditional style and offers a cost-effective alternative to our oak cladding options.

If stability, durability and beautifully grained natural cladding is required then there are few better choices than this very slow grown, incredibly dense softwood. Due to its high resin content, Siberian Larch is one of the most naturally hardy of all softwood species and highly durable without any treatment. It offers almost the same characteristics of oak at a more affordable price.

Our Siberian Larch is kiln dried to an 18% moisture content, making it ideal and ready to fix for use in both internal and external applications.

Treated English Softwood Featheredge Cladding is suitable for cladding stables, barns, pergolas and effectively any timber framed structure. It is an economical way of covering large areas.

The timber is pressure treated green with Tanalith 'E' to protect against fungal decay and insect attack. You will need to ensure that any cut ends are re-sealed with an appropriate treatment.
