About our Alder Mouldings 

Alder is a popular wood choice in traditional saunas because of its natural qualities and a low risk of twisting and warping. Alder has a beautiful light brown colour with warm pink undertones. The subtle scent resembles that of freshly cut hay that many find pleasant in the sauna. Alder does not overheat and has water repellent properties, making it suitable to be used in hot and humid environments.

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 alder moulding.  
 
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 support@finnmarksauna.com).
