5" treated tongue and groove cladding is a popular choice for exterior timber projects where durability and a clean, interlocking finish are required. Manufactured from softwood and pressure treated for outdoor use, these boards are designed to withstand exposure to the elements.
The tongue and groove profile allows each board to lock neatly into the next, creating a strong and continuous surface that helps reduce gaps and improve weather protection. This makes the cladding suitable for a wide range of garden and outdoor buildings.
