Our exterior shiplap cladding is machined in the UK from quality Scandinavian redwoods. The lap allows for some board movement which occurs when timber responds to different weather conditions. After machining the boards are pressure treated with new generation Tanalith-E preservative.
Tanalith treatment helps to protect the timber against decay and fungal attack and provides an increased service life to products made with standard dip treatment. Our redwood shiplap cladding carries the Manufacturers 15 year Treatright warranty.
