What makes this strip expand during a fire?

It's made with intumescent material that reacts to heat by swelling up and sealing gaps to slow the spread of fire and smoke.

What does "30-minute fire rating" really mean?

It means the strip has been tested to hold back fire and smoke for 30 minutes, giving occupants more time to escape safely.

Why is it important to seal the gaps around a timber door?

Even small gaps can let smoke and heat pass through quickly. Flatro fire strip blocks those gaps to buy time and increase safety.

What kind of doors work best with this strip?

It's designed specifically for timber fire doors with 2–4mm gaps, that are common in many homes and commercial settings.

Why should the strip be laid flat before use?

Laying it flat overnight helps it regain shape after being rolled, which results in proper sticking.
