When it comes to windows, various components work together to create a functional and aesthetically pleasing structure. One crucial element is the window sill, which plays a vital role in the overall performance and appearance of a window. In this comprehensive guide, we will explore everything you need to know about uPVC internal window sills, including their importance, materials, installation, and maintenance.

Importance and Functions of Window Sills

Window sills serve several important functions. Firstly, they provide structural support to the window frame, helping to stabilise the entire window structure. This is particularly crucial for larger windows or those on higher floors, where weight and pressure can be significant. 

Secondly, window sills act as a barrier against water and weather, preventing moisture from entering the interior of the building. This helps protect the window frame and surrounding walls from water damage. 

Lastly, window sills add a decorative element to a room, enhancing its overall aesthetic appeal.

Materials for uPVC Internal Window Sills

When it comes to materials, uPVC (unplasticised polyvinyl chloride) is a popular choice for internal window sills. uPVC is a durable and low maintenance material that is resistant to moisture, rot, and pests. It is also highly customisable, allowing homeowners to choose from a wide range of colours and finishes to match their interior decor. uPVC window sills are easy to clean and require minimal upkeep, making them a practical choice for busy households.

Installation of uPVC Internal Window Sills

Installing uPVC internal window sills is a relatively straightforward process. Accurate measurements of the window opening are essential to ensure a proper fit. The window sill should be cut to size and securely attached to the window frame using appropriate screws or adhesive. It is recommended to seek the professional assistance of our installers for precise and secure installation.

Maintenance of uPVC Internal Window Sills

Once installed, uPVC internal window sills require minimal maintenance. Regular cleaning with a dry microfiber cloth is usually sufficient to remove dust and debris. For stubborn stains, a mixture of water and mild dish soap can be used. Avoid using abrasive cleaners or tools that may scratch or damage the surface of the sill. It is also important to periodically inspect the window sills for any signs of damage or wear and tear. Prompt repairs or replacements should be carried out if necessary to maintain the integrity and performance of the window sills.
