Sash uPVC Windows Installation

The owner of a flat in Westminster wanted to replace ageing timber sash windows that were no longer providing sufficient insulation or smooth operation. As the property is located in a central London setting, maintaining the traditional aesthetic was essential while significantly improving energy efficiency and noise reduction.

Our Solution

We supplied and installed heritage-style uPVC sash windows, specifically designed to replicate the appearance of traditional timber frames while delivering modern performance benefits.
Key features included:

• A-rated double glazing for enhanced thermal efficiency
• Authentic sash detailing to match the building’s character
• Smooth vertical sliding mechanism
• Improved acoustic insulation, ideal for a busy Westminster location
• Secure locking systems for added peace of mind
• Low-maintenance uPVC frames requiring no repainting

The new windows preserved the period charm of the flat while significantly improving comfort and usability.

Installation Process

Our team carried out a careful removal of the original sash units, ensuring minimal disruption to the surrounding structure and internal décor. The new uPVC sash windows were installed with precise alignment and airtight sealing to maximise performance. Final adjustments were made to ensure smooth operation and a flawless finish internally and externally.
