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.

Prominent figuring

Appearance

Prominent figuring with an abundance of structurally sound live round and splay knots, some of which display cracks and chipped-off edges after machining. An occasional dead knot cannot be ruled out.

RW214 profile and RW215 profile

Profile options

We offer Thermopine® decking in the RW214 profile, specifically designed for use with our SenoFix® hidden fixing system. For enhanced safety, Russwood Anti-Slip system can be integrated into the RW215 profile, maintaining the same clean, fixing-free aesthetic while improving slip resistance.

Stability

Very stable

Stability

Thermal treatment results in substantially reduced swelling and shrinking of the timber, reducing dimensional movement by up to 50% making Thermopine® a very stable timber.

Planed, wire brushed and Anti-Slip options

Surface finish

Thermopine® decking can be planed for a smooth finish, or wire brushed to create a beautifully textured surface. Russwood Anti-Slip system can also be factory-applied for added slip resistance, making it ideal for large commercial spaces and high-traffic areas where safety is a priority.

The decking boards have prominent figuring, and any visible round and splay knots are made structurally sound during production.  

Heat, steam and pressure treatment make Thermopine very stable: dimensional movement is reduced by up to 50% compared to non-modified timber. The wood doesn’t shrink or swell, substantially reducing maintenance and extending the decking’s lifespan. This thermal treatment also makes Thermopine resistant to wood-destroying organisms. 

Uncoated boards are a uniform dark honey-brown, weathering quickly to grey. Thermopine decking can be planed for a smooth finish or wire brushed for a beautifully textured surface. We sell this decking in the RW216 profile, a grooveless decking profile specifically designed for use with our SenoFix® hidden fixing system. It is fast drying, which means it isn’t affected by slippy green algae growth.  

For enhanced safety — particularly in high-traffic or commercial areas — we can integrate our patented Anti-Slip system, maintaining a clean, fix-free aesthetic while reducing the risk of slips.

Questions?

With a wide range of timber species, board profiles, dimensions, finishes and fixing options to choose from, the possibilities are almost endless – which is exactly why pricing isn’t one-size-fits-all. To give you an accurate price, we first need to know more about your project.

Get in touch with our sales specialists for up-to-date pricing tailored to your specification. We’ll talk through your requirements and guide you to the best solution for your project and budget. To compare our decking ranges, explore indicative price bands (£–££££) using our Compare Decking Tool.

Firstly, calculate how many square metres your project will require, then add at least 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 deck is normally the last part to be completed in a new build, unless it is needed for access whilst the project is under construction.

Russwood offer a range of innovative fixing systems for decking. These include secret fix clips, adjustable substructure supports, compensation strip for enhanced ventilation and precision milled stainless steel screws. In all instances we can advise on the appropriate number of fixings you will need in order to secure your deck.

Expert View

Thermal modification gives Thermopine® decking improved dimensional stability, long term decay resistance and freedom from resin exudation. This provides a stable, consistent substrate for the application of SiOO:X coatings.
