Choose aluminium windows over uPVC if you want slimmer frames, more glass, a longer lifespan and a wider choice of colours. Choose uPVC if budget is the priority. Aluminium costs more upfront, but its strength allows larger openings and the finish can last decades.
What does aluminium do better than uPVC?
- Slimmer sightlines, because the metal is stronger than plastic
- Larger glazed openings with less frame
- A long life, commonly 30 to 45 years or more
- Many colours and finishes, including different colours inside and out
- Recyclable material
Where does uPVC win?
uPVC usually costs less and has naturally good insulation in the frame. A thermally broken aluminium frame closes most of the gap, but uPVC remains the better value for straightforward replacements.
Which is better for heat loss?
Performance depends on the whole window, including the glazing and spacer bars, not only the frame. Compare window energy ratings or Uw values rather than the frame material alone.
The choice usually comes down to appearance, size of opening and budget. Wednesfield Trade Windows is a family-run, Certass registered firm that fits aluminium windows.
