Soffit Starter Trim (J-Trim) – for 9mm Soffit Boards, 2.5m & 5m

Soffit starter trim, also known as J-Trim or U-Edge Trim, is used to create a clean and secure edge for 9mm soffit board installations. It slots over the edge of the board, holding it neatly in place under the roofline while covering any exposed cut edges.

Made from low-maintenance, durable UPVC, this trim is designed to match the full range of soffit and fascia colours for a consistent finish across your roofline. It’s ideal for both new builds and refurbishment projects.

Available in 2.5 metre and 5 metre lengths, and stocked in all matching colours: White, Black, Rosewood, Anthracite Grey, Light Oak.
