Why choose uPVC sash windows over timber?

While it is one of the most affordable window option materials available, it excels in its performance. uPVC is one of the nation's most popular materials as it's highly durable and robust so they'll continue to perform like new regardless of the weather conditions, whilst keeping your home protected from forced entry. It's maintenance-free too, so unlike timber, you won't need to apply wood protection to protect the frames. They're able to achieve low U-values and A+ energy ratings, ensuring they will improve your home’s energy efficiency.
