upvc Sliding Sash: classic charm with modern performance


Sliding sash windows blend classic charm with modern performance, making them a timeless choice for any home. Traditionally found in period properties, these windows feature vertically sliding panels that glide smoothly to open, offering a distinctive and elegant look. Their design not only adds character to your home but also allows for excellent ventilation by adjusting the top and bottom sashes for optimal airflow. The use of durable uPVC means they are low-maintenance and resistant to warping, rotting, or fading, ensuring they maintain their appearance and functionality for years to come. 

Available in a variety of finishes and colors, these windows can be customised to match the style of your property, whether it’s a heritage home or a contemporary build. With their blend of tradition and innovation, sliding sash windows are an ideal way to enhance the beauty and comfort of your living space. Checkout some recent installations below:
