Fire-Retardant uPVC Windows

uPVC is naturally fire-retardant. Here's what that means for your windows.

How uPVC behaves in fire

uPVC is inherently fire-retardant — it's self-extinguishing and doesn't support combustion the way timber does, so it doesn't help a fire spread.

What this means

Look for this

  • Self-extinguishing material
  • Doesn't support combustion like wood
  • Doesn't help fire spread
  • A safety characteristic of quality uPVC

Built to suit your openings

It's one of the quieter safety benefits of uPVC over timber — not a fireproof window, but a material that doesn't feed a fire, unlike wood.
