At CladdingKing, we supply Tradeline PVC Window Boards for homeowners and trade professionals looking for a reliable, easy-to-install solution that performs in both interior and exterior environments.

Featuring a crisp square-edge profile and a bright white finish, this 225mm wide board complements both contemporary and traditional properties. Its robust 9mm construction resists moisture, warping, rot and UV exposure, ensuring dependable performance year after year.

Suitable for Multiple Applications

The Tradeline PVC Window Board is suitable for a wide variety of projects, including internal window sills, window reveals, fascia capping and general finishing work. Its waterproof construction makes it ideal for bathrooms, kitchens, utility rooms and wet rooms, while also providing reliable protection when installed externally as a fascia cover board.

Durable Waterproof uPVC Construction

Manufactured from high-quality uPVC, this window board will not absorb moisture, swell, crack or rot like traditional timber alternatives. The durable surface resists scratches, stains and fading, helping maintain its clean white appearance without requiring painting, sealing or regular maintenance.

The smooth finish creates a modern appearance while providing a robust surface capable of withstanding everyday use in busy homes and commercial properties.

Simple and Efficient Installation

The lightweight construction makes handling and installation quick and straightforward. For internal applications, simply cut the board to the required length using a suitable uPVC saw before fixing it to the existing surface with Decorwall Megabond Adhesive or a quality grab adhesive or caulk.

When used externally as a fascia capping board, we recommend securing the board using white polytop or plastic top pins to provide a strong and professional finish.

Ideal for Roofline and Window Renovations

The 9mm thick PVC board offers excellent protection when used as a fascia capping board, covering existing fascia boards while helping prevent moisture ingress and prolonging the life of your roofline. It also creates clean, low-maintenance window reveals that eliminate the need for ongoing painting or repairs.

Maintenance is effortless, requiring only an occasional wipe with a damp cloth to keep the surface looking clean and bright.
