Our pressure treated shiplap cladding is expertly cut and machined from joinery grade Scandinavian redwood, giving a smooth, high-quality finish that’s both durable and visually appealing. Designed specifically for external use, this timber shiplap is a popular choice for garden offices, sheds, summerhouses, workshops and other outdoor buildings.

Each board is treated with Tanalith green pressure treatment, helping to protect the timber against rot, fungal decay and insect attack, even in exposed outdoor conditions. The classic interlocking shiplap profile improves weather resistance while delivering a clean, stylish appearance that can be painted, stained or left natural to suit your project.

At Dorchester Timber, we make your project easier with a free cutting service on all shiplap orders… simply provide your required sizes and we’ll cut your boards ready for collection or delivery.
