19 x 125mm (14x119mm fin) Shiplap Redwood

Our Shiplap Redwood cladding is a premium timber cladding solution that brings classic horizontal weatherboard style to external walls. Precision-machined from sustainably sourced redwood, this profile offers natural warmth, rich grain definition, and long-lasting performance when correctly specified and installed. Its overlapping shiplap design gives superior weathertightness, helping keep rain and driving wind out while creating a clean, linear aesthetic.

The 19 mm thickness and 125 mm face width with a 14 × 119 mm finished exposure make this Redwood shiplap an excellent choice for residential and light commercial façades, extensions, garden buildings, and timber frame reveals.
