"Fire retardant," "fire resistant" and "fireproof" get thrown around as if they're synonyms. They're not. Understanding the difference helps you buy the right product and spot marketing exaggeration. Here's a clear breakdown.
Fire retardant
A fire retardant slows down fire. It makes a material harder to ignite and reduces how fast flames spread across it. It doesn't make something immune to fire — it buys crucial time and limits the fire's growth. Fire retardant coatings like Aeon Core LDH Gel fall here: they treat combustible materials (wood, fabric, paper) so they resist ignition and flame spread.
Fire resistant
A fire resistant material or assembly is rated to withstand fire for a defined period — for example, a fire-resistant door rated to hold back fire for 60 minutes. It's about tested endurance over time, usually for structural or barrier elements, and is verified through standardised fire-resistance tests.
Fireproof
"Fireproof" implies something cannot burn or be damaged by fire at all. In practice, very few real-world materials are truly fireproof — the term is often used loosely in marketing. Be cautious of any everyday coating claiming to make wood or fabric "fireproof."
Quick comparison
| Term | What it means | Typical use |
|---|---|---|
| Fire retardant | Slows ignition & flame spread | Coatings for wood, fabric, paper |
| Fire resistant | Withstands fire for a rated time | Doors, walls, structural assemblies |
| Fireproof | Cannot burn (rare, often overstated) | Use the term with caution |
Which do you need?
For everyday combustible materials — furniture, panelling, curtains, packaging — you need a fire retardant to reduce ignition and flame spread. For structural barriers that must hold back fire for a set time, you're looking at fire-resistant rated products. And if a product claims to be "fireproof," ask for the evidence.
