More Information

For a classic weather‑ready timber option that’s ideal for garden projects, fencing, cladding, and exterior builds, the Treated Shiplap Timber Board – 150mm x 22mm x 4.8m (Product Code: 0415002248ST) is a dependable pick for both trade pros and DIY enthusiasts at TJ O’Mahony. This long shiplap profile board gives you a neat overlapping finish that sheds water effectively — perfect for outdoor walls, sheds, fencing or timber structures that need a clean, cladded look.

Pressure‑treated for durability, this board stands up well to the elements and provides a solid base for staining or painting if you want to customise your finish. The extended 4.8 m length makes it efficient for longer runs and reduces the number of joints you have to deal with during installation.

Key Features:
- Treated Exterior Timber: Pressure‑treated to improve resistance against decay and rot for outdoor durability.
- Shiplap Profile: Designed for overlapping installation — helps water runoff and gives a clean, consistent appearance.
- Nominal Dimensions: 150 mm (width) × 22 mm (thickness) × 4.8 m (length) — plenty of reach for long runs.
- Versatile Use: Great for cladding, fencing, outbuildings, sheds and garden timber projects.
- DIY & Trade Friendly: Easy to cut, fix and finish — an efficient choice for site work or home improvements.

Before you start installing, make sure to allow for natural size variation — timber sizes are nominal and can be around 4–8 mm smaller after machining. Always pre‑drill fixings and use corrosion‑resistant screws or nails to maintain a tidy, long‑lasting installation.
