Tradeline Square Edge PVC Window Board / Capping Board 150mm x 3m White

The Tradeline Square Edge PVC Window Board / Capping Board 150mm x 3m is a versatile finishing board designed for both internal and external applications. Manufactured from high-quality uPVC, it offers a durable, waterproof and low-maintenance alternative to traditional timber window boards and fascia boards. Whether installed as a modern window sill, fascia cover board or window reveal, it provides a clean, professional finish that stands up to everyday wear and changing weather conditions.

With its crisp square-edge profile and bright white finish, this board complements both contemporary and traditional properties while requiring virtually no ongoing maintenance.

Suitable for Multiple Applications

This versatile PVC board can be used as an internal window board, window reveal lining, fascia capping board or general finishing board. Its waterproof construction makes it particularly suitable for moisture-prone environments including bathrooms, kitchens, utility rooms and wet rooms, while also performing exceptionally well as an external fascia cover.

Durable Waterproof uPVC Construction

Manufactured from 100% uPVC, the board will not absorb moisture, rot, swell or warp like traditional timber. It also resists staining, scratches and everyday wear, making it a practical long-term solution for both domestic and commercial installations.

The durable white finish maintains its appearance without requiring painting, sealing or regular maintenance.

Simple Installation

Despite its strength, the lightweight construction makes handling and installation straightforward. For internal installations, simply cut the board to size using a suitable uPVC saw before fixing it to an existing surface using Decorwall Megabond Adhesive or a quality grab adhesive or caulk.

For external fascia applications, we recommend securing the board using white polytop or plastic top pins to achieve a secure and professional installation.

Perfect for Window Reveals and Fascia Boards

As well as creating modern window sills, the board is ideal for finishing window reveals with a clean, easy-to-maintain surface. When used externally, it provides an attractive fascia capping solution that helps protect existing roofline boards from weathering while instantly refreshing the appearance of your property.

Easy to Maintain

The smooth PVC surface requires only an occasional wipe with a damp cloth to remove dust and dirt. Unlike painted timber, it will not require sanding, repainting or specialist treatments, helping maintain its appearance for years to come.
