Loglap Board Green – 120mm x 18mm

Our Green Tanalised Loglap is the perfect solution for those looking to combine the structural integrity of a thick timber board with the classic appearance of a traditional log cabin. Unlike flat shiplap, Loglap features a decorative curved (convex) outer face that creates deep shadow lines and a robust, “chunky” feel to any exterior wall. With an 18mm finished thickness, these boards are significantly more substantial than standard cladding. This extra thickness provides improved thermal insulation, better sound dampening, and increased resistance to warping. The boards are pressure-treated with a green preservative, forcing protection deep into the timber to defend against rot, fungal decay, and insect attack for many years. We stock these boards in a wide range of lengths—3.3m, 3.6m, 4.8m, and 5.1m—allowing you to select the perfect size for your project. This versatility helps minimise waste and reduces the need for visible joints on longer spans, ensuring a professional and weather-tight finish. Log Cabin Aesthetic: The curved profile mimics the look of solid logs, providing a high-end, rustic finish to any garden structure. Heavy-Duty 18mm Thickness: Offers superior strength and durability compared to standard 12mm shiplap. Green Pressure Treated: Fully tanalised for long-term protection against the elements and ground moisture. Interlocking Tongue & Groove: Features a precision-engineered joint that ensures a secure, wind-tight, and easy-to-install fit. Multiple Length Options: Available in 3.3m, 3.6m, 4.8m, and 5.1m to suit projects of all sizes.
