Window Sills & Cover Boards

Measure from the back wall to the front edge of your existing sill, then choose a board width that covers that depth properly. Many retailers sell uPVC window sill cover boards in multiple width options because the correct width is one of the main buying decisions in this category. If you are covering an existing front lip, make sure you account for the full depth and profile shape rather than measuring only the flat top surface. This is an inference from how these products are sold in multiple widths and from the way rounded profiles are described as covering the existing lip.

Yes. uPVC window sill cover boards are a practical choice for bathrooms, kitchens and other humid rooms because they are moisture resistant, easy to wipe clean and low maintenance. Unlike timber, they do not need painting and will not rot, swell or warp in the same way when exposed to everyday condensation and splashes. That is why they are commonly used where you want a cleaner, more durable finish around internal windows.

uPVC window sill boards are often the lower-maintenance choice because they do not need painting and are easy to wipe clean. They are also resistant to moisture, so they will not rot, swell or warp in the same way timber can over time. Timber can still suit some traditional interiors, but for a practical, easy-care finish, uPVC is usually the better option.

uPVC window sill cover boards, also known as window sill capping boards or window boards, fit over an existing internal sill to give it a clean, updated finish without removing the original underneath. They are a low-maintenance alternative to timber because they do not need painting and are resistant to moisture, staining and day-to-day wear. Square edge, bullnose and slim overlay options are available depending on the finish you want and the shape of the sill you are covering. This lines up with how specialist competitors describe the category and how they position uPVC as a practical cover-over solution.

Yes. Window sill cover boards are designed to fit over an existing internal sill, which is why they are often called capping boards. Most supplier guidance describes them as being fixed in place with a strong grab adhesive or no-nails style adhesive, making them a popular option when you want to cover a tired timber sill without a full replacement.

Square edge window sill boards have a flatter, sharper front profile for a cleaner, more modern finish. Bullnose, sometimes called hockey nose, has a rounded front edge and is commonly used where you want to wrap over and fully cover the existing sill lip for a neater finish. Competitor pages consistently describe bullnose as the profile that wraps around the front edge of the sill, while square edge is positioned as the cleaner-edged alternative.
