Eurocell

Achieve flawless, professional coverage on extra-wide window sills with this 4 pack of 250mm White uPVC Capping Boards — the perfect choice for modern renovations, wide reveals, and bay window upgrades where consistency, durability, and visual impact matter. With 12 metres of total coverage included, this bundle is ideal for large domestic projects, commercial installations, or full-property refurbishments requiring a uniform, high-quality finish. Each board measures 250mm in depth, 9mm in thickness, and 3 metres in length — offering extended reach that reduces the number of joints and minimises installation time. The 250mm width is ideal for deep frames, wide reveals, or boxed-out sills where standard widths are simply not enough. Whether you’re capping over old timber or finishing a new build, these boards deliver exceptional coverage and clean lines. Manufactured from premium-grade, UV-stable white uPVC, the boards are engineered for performance in all conditions. They won’t warp, fade, yellow, or crack — even after prolonged exposure to sunlight, temperature changes, or humidity. The smooth, bright white surface is factory-finished and completely low-maintenance — no sanding, painting, or sealing required. Once installed, the boards stay looking new with only the occasional wipe clean. Despite their wide format, the slim 9mm profile keeps the boards lightweight and easy to handle, while still providing reliable structural strength. They’re specifically designed to cap directly over existing or damaged sills, helping you avoid the mess, cost, and labour of full removal. Perfect for experienced tradespeople and confident DIYers, these boards save time while delivering a crisp, seamless finish throughout the property.
