Description T&G Shiplap Tanalised-16x125x3.6m (12×119) Size: 16 x 125 (12×119) Length: 3.6m Our T&G Shiplap Tanalised (pressure treated) Timber is a high-quality, pressure-treated cladding board that combines durability with a smart, traditional finish. Designed with a tongue and groove profile and an overlapping shiplap edge, this timber offers both a secure fit and enhanced weather resistance – ideal for a wide range of construction, landscaping, and garden projects. Each board is tanalised (pressure treated) to provide long-lasting protection against rot, fungal decay, and insect attack, making it perfectly suited for outdoor use. Shiplap cladding is most commonly used for sheds, summerhouses, garden rooms, workshops, fences, gates, and garages, providing a clean, uniform look while helping to protect structures from the elements. The tongue and groove joint allows the boards to slot together securely, while the shiplap profile encourages water runoff, reducing the risk of water ingress. This makes the timber not only attractive but also highly functional in all weather conditions. Easy to work with and install, our T&G Shiplap Tanalised (pressure treated) Timber is a popular choice with both professional tradespeople and DIY enthusiasts.
