Configure nowAt windows24.com we offer three types of internal window sills: uPVC, Werzalit compact and Werzalit exclusiv. Find out more by clicking the buttons for the boards below or read on for a detailed overview.
At windows24.com we offer one window sill made from uPVC as well as two Werzalit boards made from sustainable wood. As the most affordable option, uPVC is particularly low-maintenance and insulating thanks to its innovative structure and smooth customisable UV-resistant, watertight surface. The two wooden sills, on the other hand, come with the choice of a sleek bevelled or integrated overhanging front edge and feature a configurable surface coated in tightly bonded melamine resin.
Although stone and aluminium are popular window sill materials, for an indoor window sill uPVC and compressed wood still impress the most. Where exterior sills can benefit from the weight and sheer robustness of stone to protect them from the elements, a key function of interior window sills is to seal the window and prevent heat from escaping outside. With interior chambers or a dense form, uPVC and compressed wood provide best provide this necessary insulation. Thanks to quality metallic finishes or marble decors, the look of stone or aluminium can, nevertheless, still be achieved on the surface while the core remains perfectly tailored to the practical properties required for interior sills.
The surface of an internal window sill should serve both a decorative and functional purpose. Thanks to our range of choice and the professional manufacturing processes behind our products, internal window sills from windows24.com provide just that.
Available in a classic white or elegant marble smooth semi-glossy finish, our uPVC sills brighten and complement interiors, for example, while the inherent watertight, UV, and scratch-resistant nature of the sill's modern surface ensures the coating will hold durably for years to come.
Our Werzalit internal window sills then also impress with quality colour finishes. Here multiple layers of a robust melamine resin coating are fused onto the wooden core under high temperatures.
This forms a tight bond and produces a particularly watertight, UV, scratch, and limescale resistant surface that comes in multiple colours and retains its vibrancy.
For both Werzalit compact and Werzalit exlusiv internal window boards, many smooth semi-glossy, pearl-textures, and fine-textured finish options are available. Selectable in our user-friendly configurator, bright cream, marble, or polar white are recommended to have the sill lighten interiors while a dark grey or betolit can create a darker, contemporary contrast. Other options, such as replica oak window boards or our acacia wood-replica decors add a more traditional touch, on the other hand, and bring warmth to your window.
Our smooth and semi-glossy finishes produce a particularly sleek surface surface. Cream white and marble bianco are available for uPVC sills and both our Werzalit boards can come in all the below.
Available for our wooden window sills, pearl textured finishes create a bubbled surface texture, add interest to the window area, and can be used to contrast or blend with interiors.
Available for our wooden sills, fine textured finishes produce a grain surface replicating a particular timber for a warm, traditional, and authentic look.
To ensure an accurate fit and have the window sill be tailorable to a range of different buildings, you will find an interactive dimension section in our online configurator. Here the overhang or depth of the sill can be set, as can the length by inputting the required measurements in mm into our minimum and maximum ranges.
Due to manufacturing and to ensure a uniform design some measurements, such as of the front edge or the sill's thickness, are then predetermined for each model and can be found in the configurator. The image and labels below give an idea of the range of possibilities:
Whatever internal sill you opt for, a closing edge is a final feature that can be added to all our models. Closing edges are small caps that match the colour of the window board and perfectly finish the product by ensuring a well-rounded, continuous design.
For uPVC sills the caps are made from uPVC, supplied loose, and can be easily sized and installed onto either end of the sill. For our Werzalit window boards, on the other hand, once closing edges are selected upon purchase, the Teflon caps are added under high temperatures during manufacturing and can additionally feature a long-lasting ABS coating.

How large the sill's overhang or depth should be depends on the installation situation and personal taste. A narrow sill may be more suitable for minimalist interiors, for example. We sell window sills with an overhang or depth of 100 - 550 mm and recommend that at least half of the sill rests on the masonry to ensure the necessary stability. If this is not at all possible then brackets should be installed for enhanced support.
There is no definite timeframe for when an existing window sill should be replaced but in general if rotting or water damage is seen or if the surface is fading and de-forming, replacing the sill is often recommended. A newer sill with quality modern materials will last longer and create a sleek finish while also insulating interiors. Replacing sills may also be carried out for decorative purposes to enhance interior design.
