Golden Oak UPVC Capping Board – 3m Long, 1 Pack (150mm to 300mm Depth Options)

Refresh your interior window sills with the warmth and elegance of our Golden Oak UPVC Capping Board. This 3-metre long, 9mm thick board replicates the look of natural timber while providing the benefits of a fully waterproof, low-maintenance surface. Designed to be installed directly over existing timber or MDF sills, it offers a fast and cost-effective upgrade without any need for full removal or structural alterations.

The realistic Golden Oak woodgrain finish adds a traditional touch to modern interiors, making this product ideal for heritage properties, period homes, or any setting where character and durability are both essential. Its UV-stable and moisture-resistant surface ensures long-lasting visual appeal in kitchens, bathrooms, utility rooms, and conservatories.

Each 1 Pack board comes in a full 3-metre length, reducing the number of joins and improving the final appearance. Choose from six practical widths – 150mm, 175mm, 200mm, 225mm, 250mm, and 300mm – to suit your window sills perfectly.
