uPVC interior window sills: Elegant style meets functional performance

Our quality uPVC interior window sills add a great decorative touch to rooms while also providing a durable, stable surface for plants and objects alike.

Available with a smooth, semi-glossy white or marble board cover, the sill elegantly complements a range of different interiors.

Thanks to the UV, scratch, and water resistance of the window board surface, the chosen white or marble cover is particularly durable, meaning its texture, vibrance, and form will be durably retained for years to come. 

Alongside its beautiful yet durable white or marble window board finish, a uPVC window sill from windows24.com also contributes to insulation. The innovative plastic material is manufactured with multiple chambers, for example, which creates a thermal core and helps to prevent heat from escaping. Low maintenance is also a plus. Thanks to the sill's sleek board materials any dirt or water can be easily wiped away, for example.

At windows24.com we are specialists in made-to-measure products and window sills are no exception. In our user-friendly configurator customers can set the sizes for the sill's length and depth by inputting the requirements into our minimum and maximum ranges. This ensures that the product will be perfectly tailored to your building. The colour board cover can also be selected here, as can two optional closing edges or caps. Able to be easily attached to the sill's ends, the length of these caps can be precisely adjusted and will match the chosen window board colour to round off the design by creating a continuous form.

A further key advantage of ordering a uPVC window sill from windows24.com is that the product can be easily self-installed. The process is made simple thanks to our step-by-step guides, requires some adhesive, and means customers save on professional assembly costs for a lightweight, user-friendly product.
