Finish your roofline properly with the Eurocell Black Ash 25mm Soffit Starter Trim x 5m. This J Trim provides a secure, tidy channel for the edge of a soffit board, creating a clean and professional finish where the soffit meets brickwork or fascia.
Manufactured from long-lasting, low-maintenance uPVC, it won’t warp, split or fade, and only needs a quick wipe-down to keep it looking sharp. The Black Ash woodgrain finish colour-matches perfectly with Eurocell fascia and soffit systems, making it ideal for new builds, refurb work, and replacement jobs. Installers like it because it grips the soffit firmly, cuts cleanly, and gives the job a neat, consistent edge.

What is the Eurocell 25mm Soffit Starter Trim?
The Eurocell 25mm Soffit Starter Trim, often called a J Trim, is a 5m uPVC profile used as the first fixing point when installing soffit boards. It holds the board edge securely in place, ensuring a straight, stable line and a tidy finish along the roofline. Made from long-lasting, colour-matched uPVC with a Black Ash woodgrain finish, it integrates seamlessly with Eurocell roofline products and works with both hollow and solid soffit boards.
