We use New Zealand made thermowood in our saunas, it’s durable, a better insulator and sustainable. 

Not all Sauna are created equal!

Our Thermowood (TMT) is sustainably sourced from North Island Pine, it has been heat treated for over two days, at around 210 degrees Celcius. There are no chemicals used in this modification, simply heat and steam.

Heat and Steam thermal modification.

This process removes moisture and resin, leaving a material that has a higher rot, moisture and mould resistance. The timber now has a much longer life and dimensional stability, making it perfect for applications that need resistance to warping.

Great outdoors.

Thermally modified timber is also much less prone to swelling when exposed to water, so perfect for use outdoors. It’s durability makes it a favourite with architects looking for high end exterior home cladding.

Thermowood is perfect for sauna construction.

The modified timber has reduced thermal conductivity of 20-25%, when compared with other non treated coniferous wood, such as regular pine or cedar. As it is great for keeping in heat, thermowood is perfect for use in outdoor saunas.

Built to last.

Thermally modified wood is a durable timber with a caramel tanned appearance.
