Vertical Sliding uPVC Sash Windows
Heritage Charm with Modern Comfort
At UGS Ltd, our uPVC sash windows (vertical sliders) provide a cost-effective, low-maintenance solution for homeowners who appreciate classic design and reliable performance. uPVC is valued for its weather resistance, energy efficiency, and ease of care, making it an excellent choice for vertical sliding windows. With their smooth operation and heritage-inspired look, uPVC vertical sliders offer effective ventilation, modern security, and traditional charm—ideal for both period homes and new builds alike.
uPVC sash windows are designed with multi-chambered frames to improve insulation and reduce heat loss. When combined with high-performance glazing, they help maintain a stable indoor temperature throughout the year—cutting energy costs and supporting a more sustainable home. Their sleek, moulded frames allow for generous glazing areas, welcoming natural light and enhancing the sense of space in any room—making them a practical and attractive addition to your property.
One of the key benefits of uPVC is its affordability, durability, and minimal maintenance, making it a practical and long-lasting window solution. uPVC sash windows do not require painting or sealing and retain their appearance with simple cleaning. Available in a wide range of colours and woodgrain-effect finishes, uPVC vertical sliders can be styled to suit both modern homes and traditional properties—offering a versatile and cost-effective alternative to timber or aluminium.
At UGS Ltd, we supply high-performance uPVC sash windows that combine traditional aesthetics with modern functionality. These vertical sliders feature multi-chambered frames for improved insulation and can be fitted with secure locking systems for enhanced safety. Whether you're upgrading period-style windows or looking for a low-maintenance solution with authentic charm, uPVC sash windows offer an excellent balance of energy efficiency, value, and visual appeal.

Profile
At UGS Ltd, we supply and install uPVC Vertical Sliders in two distinct profiles—Standard and Slim—each offering a unique blend of style and performance.
Standard
At UGS Ltd, we are proud to work with industry-leading manufacturers such as Cortizo, Deceuninck, Kommerling, Rehau, Reynaers, Schuco, and SMART to provide top-quality sash windows. Our standard profile sash windows are designed with robust frames, ensuring excellent thermal insulation, soundproofing, and durability for your home.
The standard sash window profile offers a traditional, classic appearance with a slightly thicker frame, providing superior strength and stability. This makes it an ideal choice for homeowners seeking a timeless aesthetic while benefiting from modern performance standards
The standard profile remains a popular choice for those prioritising a balance of elegance, durability, and insulation, particularly in period properties or homes that require a more substantial frame.
Our standard sash window profiles deliver exceptional quality and performance, making them a versatile option for any project.
Slim
Our slim sash window profiles are designed with narrow frames, offering a sleek and modern look that maximises natural light and provides a larger glass surface. These profiles are perfect for homeowners who want a clean, minimalist aesthetic while still enjoying the classic charm of sash windows. The slim design sits in line with the window frame, creating a smooth, contemporary finish that is ideal for both modern and traditional homes seeking a more subtle appearance.
In contrast to standard profiles, which offer a thicker frame for added strength and a more traditional look, slim profiles provide a more streamlined appearance without compromising on performance. While standard profiles focus on insulation and durability, slim profiles offer the same energy efficiency but with a focus on maximising light and creating a visually lighter feel. With UGS Ltd, you can combine style and functionality to achieve the perfect look for your home.
At UGS Ltd, our sash windows (vertical sliders) are available with both double and triple glazing options to provide superior energy efficiency and comfort for your home. Whether you choose double or triple glazing, both offer excellent thermal insulation and noise reduction, making your home more comfortable and energy-efficient year-round. For enhanced performance, our glazing units can be filled with argon gas, an inert gas that increases thermal efficiency by reducing heat transfer through the glass. Argon-filled windows also help to reduce condensation buildup and improve overall energy savings, ensuring a warm, comfortable environment while lowering energy bills. For character properties or listed buildings where replacing the original windows is not possible, secondary glazing units are the ideal solution. They preserve the exterior charm while significantly improving insulation and noise reduction. To learn more, visit our Secondary Glazing Unit page for more details on how this can be the perfect upgrade.
