What Are Sliding Sash Windows?
Sliding sash windows, also known as vertical sliding windows, are a traditional window style where one or both sashes slide vertically to open and close. Originally found on Georgian and Victorian homes, they remain one of the most popular choices for homeowners wanting timeless character with modern performance.
At Lion Guard Windows & Doors, our made-to-measure uPVC sliding sash windows combine authentic heritage styling with modern energy efficiency, secure locking systems and low-maintenance materials. They are ideal for both traditional and modern homes across Swansea, Carmarthenshire and South West Wales.
Designed For Comfort, Security & Everyday Performance
Our sliding sash windows are designed to deliver traditional appearance without compromising on modern-day performance. With energy-efficient glazing, secure locking systems and durable weather-resistant materials, they help improve comfort, security and thermal efficiency throughout the year.
Explore colours, glazing styles, hardware and sash configurations to create the perfect look for your home. Our family-run Swansea and Carmarthenshire team will help you design made-to-measure sliding sash windows tailored to your property.
