Our 120mm x 12mm shiplap is a high‑quality, pressure treated timber solution designed to deliver durability, protection, and a clean, attractive finish to outdoor structures. Made from planed softwood, this cladding offers a smooth surface that enhances both appearance and performance.
Cut with precision tongue and groove edges, each board fits neatly together to create a strong, weather‑resistant profile with a consistent 110mm coverage. The overlapping shiplap design helps direct water away from the surface, making it an excellent choice for long‑lasting external cladding applications.
Ideal for sheds, garden rooms, garages, and gates, this treated shiplap cladding is built to withstand the elements. Pressure treatment helps protect the timber against rot, decay, and insect attack, ensuring a longer service life and reduced maintenance over time. To keep your cladding looking fresh and protected year after year, check out our range of preservatives and paints. Whether you’re upgrading an existing structure or starting a new project, this shiplap delivers both reliability and visual appeal.
