How to Identify Fake or Low-Quality uPVC Windows – Madurai Buyer Alert
Published on 27 Jul, 2025
Not all uPVC windows are the same — some low-grade products may look fine at first but crack, fade, or fail within months. As a Madurai homeowner, you deserve original, weather-resistant windows that last for years. Here’s how to spot fake or low-quality uPVC and avoid costly mistakes.
❌ Common Signs of Fake uPVC Windows
1. Flimsy or Thin Frames
Fake frames often use underweight, low-thickness profiles.
Original uPVC should feel sturdy, with reinforced chambers inside.
2. No Branding or Batch Details
Authentic materials come with profile brand embossing or batch numbers.
No markings = red flag!
3. Yellowing or Dull Color
Fake windows discolor quickly under sunlight.
Genuine uPVC is UV-stabilized and retains its white or laminated finish for years.
4. Loose or Weak Welding at Corners
Poor-quality frames have weak joints that may show gaps or cracks.
Original windows have clean, pressure-welded corners.
5. Low-Grade Hardware
Cheap handles, rust-prone hinges, and noisy rollers are signs of fake setups.
Original uPVC windows use stainless-steel or powder-coated hardware with smooth movement.
6. Poor Sealing
Fake windows may leak during rain or let in dust.
Check the rubber gaskets — original systems are airtight and water-resistant.
🧪 Quick Home Tests You Can Try
- Press the frame lightly — if it bends easily, it’s poor quality
- Scratch test — fake plastic flakes or peels
- Tap the glass — cheap glass sounds hollow and may rattle
