Aluminium vs uPVC Windows in Singapore: Which Is Better?

When replacing windows, the frame material matters as much as the glass. In Singapore, aluminium dominates — but uPVC has its place. Here’s how the two compare so you can choose well.

Key takeaways

  • Aluminium is strong, slim and durable — the Singapore standard, especially for HDB.
  • uPVC offers good insulation and a different look, but is less common here.
  • Aluminium suits large panes and slim, modern sightlines.
  • For HDB windows, use HDB-approved contractors and materials.
