Product description

Thermo Aspen Sauna Wood Cladding Kallio 120mm by Kärävä (Pack of 6)

Our Thermo Aspen Sauna Wood Cladding (Kallio)

Our Kallio sauna wood interior cladding is a sustainable and durable product which is produced in Finland by a family-owned company Kärävä that creates beautiful results in any sauna. The Kallio cladding profile has a tongue and groove design that is easy to install on the sauna wall. The deep grooves on the back of the cladding allow moisture to run down to the floor, allowing the wood to dry out after a steamy sauna session. This ensures the longevity of the sauna walls and ceilings.   

This cladding material is well suited for your next DIY project.

About our Thermo Aspen Wood Sauna Cladding

Our thermo aspen is created by heat-treating the soft timber. The natural heat treatment reduces moisture levels of the wood, giving it a tough and rot resistant structure, which does not secrete resin in high temperatures and the moisture rich environment of a sauna. Thermo aspen has a pleasant, toasted scent and a honey-brown colouration. The grain of thermo aspen sauna wood products is straight and knot-free, making it a comfortable and stylish timber choice for a sauna.

Information on our Kallio Profile

Choosing your sauna panels is all about your personal preference and we have styles to fit the atmosphere and interior specs you wish to create. Our Kallio profile has a tongue and groove design that is easy to install on the sauna wall. Kallio is a proprietary tongue and groove profile. Visually, it is a balance between the industry-standard STS4 profile and STP profile.

The profile can be used for interior features, exteriors when thicker 19mm cladding is used, and of course as a tongue and groove cladding option for your sauna. The Kallio profile timber has a 2mm radius on the two front edges and large grooves on the back face which allow water from the sauna to run down behind the cladding and onto the floor rather than sitting on battens or being trapped behind the boards. This means water is not sat in direct contact with the timber cladding and reduces the chances of your sauna developing issues with mould or rot.

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 Aspen 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
