uPVC Windows
Stylish, Energy Efficient Windows for Homes Across Oxford, Bicester, Witney, Abingdon & Beyond
At Isis Windows, we understand that choosing replacement windows is about far more than simply replacing old frames. Across Oxfordshire, homes have a distinctive character — from elegant period properties in North Oxford and Headington to modern family homes in Bicester, Witney and Abingdon, as well as charming cottages throughout the surrounding villages.
That’s why we offer several different uPVC window systems to suit different property styles, finishes and budgets. Whether you want a traditional timber-look flush window for a period home or a clean contemporary design for a modern extension, we can help you find the right option for your property.
We install high-quality double glazed uPVC windows throughout Oxfordshire, including Oxford, Kidlington, Woodstock, Thame, Banbury, Didcot, Carterton and the surrounding areas.

Choosing the Right uPVC Windows for Your Home
Every home is different, and certain window styles naturally complement certain properties better than others.
For example:
- Traditional cottages and heritage homes often suit flush sash windows with authentic timber-style detailing.
- Victorian and Edwardian homes in areas such as Oxford and Headington can benefit from heritage-inspired designs that retain character while improving insulation.
- Modern homes and extensions often work best with sleek contemporary frames and larger glazed areas.
- Family homes across Bicester, Witney and Abingdon usually benefit from practical, energy-efficient window systems that balance appearance, security and affordability.
To make things simpler, Isis Windows offers three main uPVC window systems, each designed to suit different styles of property and homeowner preferences.
