Why We Build in uPVC, Not Aluminium

We're a uPVC maker — here's an honest explanation of why, including where aluminium genuinely wins.

How they differ

Aluminium window frames are strong and slim, which lets them carry large panes with thin sightlines. But aluminium conducts heat readily, so an aluminium frame transmits more heat than uPVC unless it has a thermal break.

uPVC frames are multi-chambered — the hollow chambers trap air, which slows heat transfer. That makes uPVC naturally insulating without needing a thermal break.

How they compare

Look for this

  • uPVC insulates naturally in our heat
  • No corrosion in humidity
  • Zero maintenance for the owner
  • Takes glazing and sealing well
  • Aluminium wins on slim sightlines

Our honest take

We're not neutral, so here's the honest version: we build in uPVC because its natural insulation and zero maintenance suit Coimbatore homes best. Where you want very slim sightlines on a big span, aluminium genuinely wins — and we'd tell you that rather than lose your trust.
