Non-combustible ROCKWOOL

ROCKWOOL products are rated non-combustible.

Non-combustible ROCKWOOL insulation acts like fire barrier and does not contribute to fire. The level of protection can further be enhanced with smoke detectors, fire alarms and sprinkler systems.

ROCKWOOL products has been classified as belonging to Euroclass A1 following EN 13501 reaction to fire tests. It has also been classified as such in national reaction to fire evaluations outside the EU system.

The Euroclass A1 rating confirms that it does not cause any sustained flaming in the non-combustibility test. In A1 products containing any organic component, the energy which is released will be very limited.

The A2 rating confirms that it does not show any sustained flaming for more than 20 seconds in the non-combustibility test. A2 products must also satisfy the strict requirements of fire contribution, smoke intensity and burning droplets tests.

So, whilst the obvious reason for choosing a ROCKWOOL insulation product often is due to the thermal and acoustic properties, its behaviour in the presence of intense heat or fire are also important considerations for architects, builders and homeowners.
