White UPVC Capping Boards – 9mm, 2.5m & 5m Lengths

Our white 9mm UPVC capping boards are ideal for covering existing timber fascias, providing a clean, professional finish without the need for full replacement. Lightweight and easy to install, they’re perfect for refurbishment jobs where the underlying wood is still structurally sound.

These boards are also commonly used as external window sills, offering a low-maintenance, weatherproof alternative to traditional timber or painted finishes.

Made from durable, colour-fast UPVC, they’re designed to resist warping, cracking, and discolouration. All boards are colour-matched to our white fascia and soffit ranges for a consistent appearance across your installation.

Available in a wide range of widths from 150mm to 605mm, and in either 2.5m or 5m lengths.
