ThermoSpruce Multi-use Decking Boards

Exteriors – Interiors – Decking – Joists – Soffits – Flooring – Wall panels

Our Benchmark ThermoSpruce Decking, sourced in Scandinavia, offers a softwood solution with exceptional rot resistance and longevity combined with rustic knots and a naturally light colour. When installing, it’s important to ensure that the heartwood (the side of the board closer to the centre of the tree) is facing downwards.

Multi use applications of this visually attractive, low maintenance high durability timber include decking boards (20mm and 42mm) and decking joists (42 x 150mm) for long life decking. Our 20mm X 140mm decling boards are ideal for facings and soffits offering a durability class 1 rot free life of many decades.

We can offer our ThermoSpruce Decking with the Nordic Swan Ecolabel. Wood that carries this Ecolabel comes from responsibly managed forests, is chemical free and offers great durability in outdoor conditions.

For a long life deck use our 42 x 140mm joists – our thermowood timber will ensure sub structure integrity over decades unlike chemically impregnation treated timbers that will start to rot in a few years.

When deciding on the quantity to order be sure to allow for cutting waste (normally allow +10%) and to allow for gaps (i.e.: decking) or board joints/overlaps (i.e. T&G) as appropriate. QEH will ship the requisite number of boards. Where end matching is offered, board joins do not necessarily need to align with joists or battens. Check Thermory installation instructions carefully.

It takes more than just a good-looking product. At Quality European Hardwoods, our ThermoSpruce Decking is designed, treated and milled with the perfect outdoor experience in mind. Each board is naturally beautiful, expertly modified and highly functional – the perfect mix of art and science.

Our Decking boards undergo intense thermal modification, which gives them unrivalled durability and stability that runs all the way through to the core.

Our Decking solutions are easy to install and provide the long-lasting comfort and visual appeal for which our products are so well known. Expand your living space and move one step closer to nature.
