Effortless Elegance and Durability: UPVC Window Sills and Cover Boards

Enhancing your home's aesthetics has never been easier, thanks to our exceptional UPVC Window Sills and Cover Boards. Crafted from high-quality UPVC, a preferred material for interior construction projects, these superior products outshine traditional alternatives in every way. They not only exude style and practicality but also eliminate the need for labor-intensive tasks such as sanding and painting.

The beauty of our window boards lies in their minimal maintenance requirements, ensuring long-term savings of both time and money. With built-in color fastness and UV stability, they stand strong against the sun's harsh rays, maintaining their allure without fading or UV-induced damage.

For a perfect blend of cosmetic appeal, robust performance, and affordability, our Window Sills and Cover Boards excel in every aspect. They outperform conventional options and offer a host of remarkable benefits. With an impressive selection of visually appealing finishes and swift delivery services across the UK, our window boards are the ideal choice for your project.

  1. White Window Board & Sill

  2. Anthracite UPVC Window Board & Sill

  3. Black Ash UPVC Window Board & Sill

  4. Rosewood UPVC Window Board & Sill

  5. Golden Oak UPVC Window Board & Sill

  • Class 1 fire and flame resistance rating

  • Scratch resistance

  • UV stability

Our window board products are perfectly suited for internal use, serving as ideal replacements for worn-out wooden window boards and sills. Whether for renovations or new construction, these products find a place in homes, including extensions, conservatories, and outbuildings.

Modern window sills and cover boards favor UPVC for good reason. Traditional wood-based alternatives demand regular maintenance, requiring sanding, painting, or staining every few years. Additionally, wood poses a fire risk and degrades when exposed to sunlight, leading to issues like cracking, peeling, and fading.
