Full house installation of slate grey on white PVC sliding sash windows with arched heads and Georgian bars

Heritage styling with modern performance

We recently completed a full house installation of slate grey on white PVC sliding sash windows featuring arched heads and vertical Georgian bar detailing, transforming the property with a striking blend of traditional character and modern efficiency.

This project required careful attention to detail to maintain the architectural style of the home while significantly upgrading performance and security.

Project overview

The homeowners were looking to:

  • Replace outdated window units

  • Retain the property’s traditional charm

  • Incorporate arched window detailing

  • Improve energy efficiency

  • Choose a distinctive yet elegant colour finish

The chosen design combined classic sliding sash styling with contemporary colour and glazing features, resulting in a truly standout installation.

Slate grey on white – a sophisticated contrast

The dual-colour finish of slate grey externally with white internally offers the best of both worlds. The benefits of dual colour frames are:

  • Strong kerb appeal with a modern grey exterior

  • Bright, neutral white interior finish

  • Complements both stone and brick façades

  • Contemporary look without overpowering the property

Slate grey has become increasingly popular across the North West for homeowners wanting a refined alternative to anthracite.

Sliding sash windows with authentic detailing

PVC sliding sash windows replicate the traditional timber box sash appearance while offering the performance advantages of modern materials. Key features are:

  • Smooth vertical sliding mechanism

  • Tilt-in functionality for easy cleaning

  • Secure locking systems

  • Energy-efficient double glazing

  • Low maintenance construction

The addition of vertical Georgian bars enhances the traditional aesthetic, creating the appearance of classic multi-pane sash windows.

Arched head windows – architectural impact

One of the standout elements of this installation was the inclusion of arched head frames, carefully manufactured to match the existing openings. Arched windows:

  • Add unique architectural character

  • Enhance period-style properties

  • Require precise measurement and fitting

  • Create a softer, more elegant façade

The finished result maintains the original charm of the property while delivering modern comfort and security.

Energy efficiency and comfort

The new PVC sliding sash windows significantly improved the home’s insulation and overall performance. Benefits include:

  • Reduced heat loss

  • Elimination of draughts

  • Improved acoustic insulation

  • Lower energy costs

  • Increased security

The homeowners now benefit from a warmer, quieter and more secure living environment.
