Fire-Stopping

ROCKWOOL stone wool products and systems harness the seven strengths of stone to provide effective fire stopping protection. 

Most casualties in a fire are caused by toxic smoke inhalation². Our stone wool does not contribute any significant toxic smoke.

Stone wool is also engineered using the same processes that take place at the heart of a volcano. This means our products are non-combustible and can withstand temperatures exceeding 1000°C, without losing their strength or dimensional stability. 

This same quality of fire resilience is what allows ROCKWOOL firestop insulation to prevent the spread of fire when installed.

However, our range goes even further than just the insulation factor. It specifically addresses the optimal treatment of every element or building part which could weaken the integrity of the building.

Key tips: 

• Ensure the guidelines set out in product datasheets and brochures are followed to achieve optimum performance levels.
• Consult relevant installation guide videos where available.
• Make sure you have enough materials such as sealants to complete a particular task in one go, as re-applying the sealant may not provide effective cover.
• It is highly recommended that only a certified specialist installer applies this product range.
