About our Thermo Radiata Sauna Wood Cladding 

Thermo radiata pine is a stylish dark brown wood type with very few to no knots. It does not secrete resin when it gets hot, making it comfortable to lean against in a sauna. The low-density structure and resistance against splitting or splintering makes it a great choice for sauna walls and ceilings. Thermo radiata pine has unique, striped grain colour and patterns, creating a beautiful look into a room where a darker aesthetic is desired.

Information on our STS4 Profile 

Choosing sauna panels is all about your personal preference and we have styles to fit the atmosphere and interior specs you wish to create. The STS4 profile gets its name from the 4mm gap between each board. The STS4 panels have slim, angular grooves, which make this sauna wood cladding a great choice for a modern sauna where a symmetrical, strong aesthetic is desired. The STS4 profile is a popular choice in contemporary saunas.

Shipping Information on Sauna Timber 

Depending on the size and quantity of your sauna timber order, the shipping costs may vary and will be calculated at checkout. Shipping costs also differ between UK Mainland, Highland and Island postcodes. Many of our timber products will be shipped using a palletised shipping service due to their big and bulky nature and may require a kerbside drop or handballing off the freight vehicles. Please take time to read our Shipping and Delivery Information carefully before placing an order for our thermo radiata cladding. 
Please note that due to certain constraints of our shipping networks, we usually ship timbers of up to 2400m lengths, beyond those lengths the costs for shipping will increase quite significantly. If you do require longer timber lengths, our shipping calculator will indicate associated costs for such shipping. 

If we do not have your required length, but have a longer length available, to avoid higher shipping rates, it is worth considering our cutting service. You will still need to purchase the full length, but for a small fee, we can cut this down to your desired length to help reduce shipping costs. The off-cut will be added onto the pallet. 
For longer lengths or our cutting service, please call or email our Customer Service Team who will be happy to arrange alternatives (+44 (0) 20 8050 2895 or
