How fire-resistant are uPVC windows? Here's an honest explanation.
uPVC is fire-retardant — it resists ignition and is self-extinguishing, not supporting a fire the way combustible timber does. This makes it a safer frame material than wood in a fire.
For everyday home safety, uPVC's fire-retardant nature is a genuine plus over timber. Formal fire-resistance ratings involve specialised glazing systems, which we can advise on if you need them.
uPVC is fire-retardant — it resists ignition, is self-extinguishing, and doesn't feed a fire like timber. That's a safety plus, though not the same as formally fire-rated glazing.
