Highlights Of Sliding Sash Windows

We work with trusted specialists Roseview windows and Glyngary windows, giving us the flexibility to offer sliding sash window solutions in both uPVC and timber to suit a range of styles, performance needs and budgets. This means we can help you find the right option for your home, whether you’re looking for the low-maintenance practicality of uPVC or the authentic character of handcrafted timber. Across both ranges, our sliding sash windows are designed to deliver excellent thermal efficiency, robust security and long-lasting, low-maintenance performance – helping to keep your home warmer, quieter and better protected, without compromising on traditional style.

Timeless Aesthetic

Sliding sash windows offer a classic, elegant look that enhances the charm and character of any home, blending seamlessly with both traditional and contemporary styles.

Energy Efficiency

Modern sliding sash windows are designed with advanced insulation features, reducing heat loss and improving energy efficiency, leading to lower energy bills.

Enhanced Security

Equipped with robust locking systems, sliding sash windows provide enhanced security, ensuring your home is well-protected.

Low Maintenance

Constructed from durable materials, sliding sash windows require minimal maintenance while retaining their appearance and functionality for years, making them a practical choice for busy homeowners.

uPVC Sliding Sash Windows

uPVC sliding sash windows offer all the character of a traditional box sash, without the ongoing maintenance timber can demand. Constructed with low thermal conductivity profiles, they deliver excellent insulation, reduced noise transfer and enhanced security, while remaining available in a wide range of woodgrain finishes and colours to replicate the appearance of a period timber sash.

Our uPVC sliding sash windows are available in Roseview’s Ultimate, Heritage and Charisma Rose ranges, each combining classic sash proportions with modern uPVC performance:

Ultimate Rose – the closest match to authentic timber detailing, ideal for period and listed-adjacent properties.
Heritage Rose – blends traditional elegance with everyday practicality.
Charisma Rose – a budget-friendly, low-maintenance option that still retains the charm of a traditional sash design.

All ranges can be specified with double or triple glazed sash windows for improved energy efficiency, and with spiral balance or traditional weighted mechanisms depending on the look and feel you’re after. Spiral balance options can also meet PAS24 security standards, making them a popular choice for homeowners prioritising both style and security. If you’re weighing up uPVC sash windows cost against a timber alternative, our team can talk you through the options during a showroom visit or quote.

Timber Sliding Sash Windows

For homeowners who want the genuine article, our timber sliding sash windows are handcrafted to combine timeless aesthetics with smooth, durable operation. Available through Glyngary, our wooden sash windows are built using traditional joinery techniques and finished to complement both period and contemporary Surrey properties. Choose from:

Spiral balance sash windows – frictionless, low-maintenance operation that can meet PAS24 security standards.
Traditional lead-weight sash windows – the classic cord-and-pulley mechanism, using concealed weights to perfectly balance the sash for smooth, authentic up-and-down movement.

Timber sliding sash windows are particularly well suited to period and conservation-area properties across Surrey, where matching original glazing bar profiles and sightlines is often a priority. As with our uPVC ranges, timber sash windows can also be specified with double or triple glazing to significantly improve on the thermal performance of original single-glazed sashes, without compromising on appearance.

Victorian & Georgian Sash Windows

Sliding sash windows have been a defining feature of British homes since the Georgian era, and remain synonymous with the elegant proportions of Victorian and Georgian architecture found throughout Surrey. Traditional Georgian sash windows are typically characterised by multi-pane glazing bars arranged in a symmetrical grid, while Victorian sash windows often feature larger panes of glass, reflecting the glass manufacturing advances of the period.

Whether you’re restoring a period property or simply want to introduce that traditional look to a newer build, we can replicate authentic Georgian and Victorian glazing bar patterns, horns and sightlines in both uPVC and timber, while upgrading performance with modern double or triple glazing. This makes it possible to retain the character that makes these homes so distinctive, without living with the draughts, heat loss and security compromises of the original single-glazed sashes.

We regularly help homeowners across Leatherhead and Surrey specify traditional and replacement sash windows that respect a property’s period features – particularly important in conservation areas, where retaining the original look and proportions is often a key consideration.
