Thermopine® exterior cladding
Our Thermopine cladding is made from Scots Pine which is heat treated to enhance stability and durability. It has prominent figuring, with round and splay knots that are made structurally sound during production.

Species
Scots Pine
Origin
Northern Scandinavia
Appearance
Prominent figuring with an abundance of knots
Appearance
Prominent figuring with an abundance of structurally sound butterfly and round knots, some of which display cracks and chipped-off edges after machining. Brushing creates texture and turns knots into a feature. An occasional dead knot cannot be ruled out.
Grade
Follows our stringent in-house grading process, with every board graded by hand
Grade
Thermopine® is the heartwood of Scandinavian Scots Pine, thermally modified to create a dimensionally stable timber free from resin. Re-graded in-house to our own exacting standards, meaning less sorting, less wastage and less time lost on site.
Modified timber
Yes
Modified timber
Scots Pine is thermally modified using only heat and steam. No chemicals or hazardous substances are used.
SiOO:X coating
Suitable for coating with SiOO:X
SiOO:X coating
Thermopine® can be factory coated in-house with SiOO:X Wood Protection.
Durability
Exceptional durability
Durability
Exceptional durability (Class 2 – 3 BS EN 350-2).
Stability
Very stable
Stability
Thermal treatment results in substantially reduced swelling and shrinking of the timber, reducing dimensional movement by up to 50%. This makes Thermopine® a very stable timber.
Coatings
Thermopine® is highly versatile and pairs well with either SiOO:X or our water-based oil systems. Paint is also available for projects requiring a fully opaque finish. All coatings are applied factory in-house.
Surface finishes
Recommended surface finishes depend on the coating system and your project specification. Please contact our Specification Team for further information.
Fire retardant
Select profiles are suitable for treatment with Burnblock®, please contact our Specification Team for further information.
Sustainability
Sustainably sourced from well managed forests. EPD available.
Weathering
If left uncoated, Thermopine® will weather to grey over time, however due to its superior coating performance, boards are most commonly supplied coated.
Density
Low – classified by BS EN 350-2 as approximately 420 Kg/m³ at a moisture content of approximately 6-8%.
Application
Thermopine® is our most versatile cladding product, thanks to its wide range of stock sizes and excellent price-performance ratio. Various lengths, including fixed lengths, available from stock.
See how Thermopine® compares with other species.
Uncoated Thermopine is a uniform dark honey-brown colour which quickly weathers to grey — but we most commonly supply it coated with SiOO:X, painted or finished with our water-based oils.
Since Thermopine doesn’t shrink and swell like unmodified wood does, coatings can last up to three times longer than on non-modified timber. We factory coat the timber boards on our premises, ensuring quality control and further enhancing adhesion and longevity compared to on-site application. The thermal treatment has the added benefit of making Thermopine cladding resistant to wood-destroying organisms, and gives the timber the same durability classification as oak.
Finishes
Learn more about our range of cladding surface finishes; from smooth, planed boards, to textured finishes specifically developed to enhance coating performance.
Planed
Planed boards are run through our planing mill to create a smooth, dressed finish.
Brushed
To create this effect, wire brushes are used to pull out the softer spring wood, exposing the harder summer wood, thus accentuating the grain and creating a beautifully textured surface.
Microtex®
A fibrous surface finish designed to provide optimal performance of SiOO:X coatings.

Coatings
Thermopine can be factory coated in-house with our range of coating systems to suit your project vision, including our water-based oils, paint systems and SiOO:X Wood Protection for a weathered appearance at an accelerated rate. Thermopine can also be fire retardant treated with Burnblock®, which is compatible with SiOO:X Light Grey or Mid Grey coatings.
Oil
A range of matt finishes which highlight the natural beauty and variation of timber.
SiOO:X
SiOO:X Wood Protection eliminates differential weathering and provides a consistently weathered tone.
Paint
A traditional coloured paint finish in opaque and translucent options.
Recommended fixings
How timber is fixed is fundamental to its long-term performance, influencing both its appearance and durability. Each Russwood species, profile and layout combination has a recommended fixing system, with detailed drawings available to help ensure the timber performs and looks its best for years to come. These are the recommended fixings for use with Thermopine.
