The Eurocell Black Ash 40mm Soffit Joint (5m) is designed to create a neat, consistent joint between flat soffit boards, helping maintain straight lines and a uniform finish across the underside of the roofline.
Manufactured from rigid uPVC and finished in a Black Ash grained foil, the joint is colour-matched to Eurocell Black Ash soffit boards and trims. It is typically used where multiple boards meet across wider soffit areas, allowing for controlled movement while keeping joints clean and visually consistent.
The 40mm profile provides sufficient coverage to conceal board edges and fixings, improving the overall appearance of the soffit installation. Once fitted, the joint requires no painting or treatment and remains stable in exposed roofline conditions.

Typical Installation Use
Soffit joints are fitted between adjacent soffit boards on wider roof overhangs, porch canopies, and boxed soffit areas. Once the boards are cut to width and fixed in place, the joint is used to cover the meeting edge, helping maintain straight runs and a professional finish across the elevation. The Black Ash finish ensures the joint blends seamlessly with darker fascia and soffit systems.
