Sash uPVC Windows

This project took place in a Victorian terraced home in Oval, London. The property’s original timber sash windows had become draughty, difficult to operate, and costly to maintain. The homeowners wanted to preserve the period character of their home while benefiting from modern energy efficiency, noise reduction, and improved security.

Our Solution

We recommended high-quality uPVC sliding sash windows designed to replicate the traditional timber look. These windows featured slim sightlines, decorative glazing bars, and run-through sash horns to maintain authenticity. At the same time, they provided modern benefits such as:

• Double-glazed A-rated units for better insulation
• Tilt-in function for easy cleaning from inside the home
• Smooth, low-maintenance uPVC frames
• Secure locking systems for peace of mind
• The windows were finished in classic white to match the home’s original style and to comply with local planning requirements.

Installation Process

The installation was completed over three days. Our team carefully removed the old timber sash frames while preserving the surrounding brickwork. The new uPVC sash windows were installed with precision, ensuring smooth sliding operation and airtight sealing against draughts. Internal trims and reveals were finished neatly, and the windows were tested to guarantee ease of use and security.
