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.
