Western Red Cedar Cladding (18mm x 144mm) (136mm Cover)

Product Description Our Western Red Cedar PTGV1S Cladding (18mm x 144mm, 136mm cover) is a high-end timber solution designed to deliver both outstanding visual appeal and long-term performance. Manufactured from premium-grade cedar, this profile offers a refined, modern finish suitable for a wide range of external and internal applications. The PTGV1S (Planed Tongue & Groove V-Joint, one side) profile ensures tight, consistent board alignment while creating a subtle shadow line between boards, adding depth and character to the finished installation. Once installed, each board provides a 136mm cover, giving a clean and uniform appearance across the surface. Western Red Cedar is widely regarded as one of the finest timbers for cladding due to its natural resistance to decay, moisture, and insect attack, making it an excellent choice without the need for chemical treatment. Its low density also makes it easy to handle and install, while its natural oils help it withstand the elements over time. Left untreated, cedar will weather gracefully to a silvery-grey patina, or it can be coated to retain its warm reddish-brown tones depending on your design preference. Available in 4.88m and 5.18m lengths, these longer boards reduce joins and deliver a more seamless, professional finish—particularly important on larger elevations.

Another common rule in cladding: “what you don’t see matters as much as what you do”—proper battening, airflow, and fixings are critical to long-term performance.
