How Blue60 Fire-Rated Foam Achieves Fire & Acoustic Compliance

Written by Blue60 | Nov 5, 2025 10:00:01 AM

Blue60 fire-rated foam is a specialist product that’s designed for fire resistance but that also offers acoustic insulation. The foam seals gaps between doorsets and walls, and prevents fire and smoke passage for passive fire protection.

Blue60 fire foam is engineered to be quick and easy to use. Tested to ensure it meets the required standards, the foam provides a robust solution for fire door installations.

Acoustic Benefits

Though the primary function of Blue60 is to maximise fire-resistance, the foam’s density and expansion capabilities also reduce sound transfer through sealed gaps. In fact, the fire-rated foam is able to reduce sound by up to 43dB.

This means the foam can simultaneously enhance the acoustic performance of the sealed area while providing fire protection. This dual functionality can help minimise sound disturbances in commercial properties and other large buildings. It also gives Blue60 an advantage over other fire-stopping materials that aren’t as acoustically effective.

Fire Resistance Characteristics

Blue60 fire-rated foam undergoes rigorous testing to ensure it meets important fire resistance standards. The foam is specifically designed to resist fire and smoke for up to 60 minutes when integrated into a compliant fire door system.

Using the foam when installing a fire door, particularly when sealing the perimeter gap around the door frame, is crucial as it helps to maintain compartmentalisation within the building. This ensures the fire door assembly can effectively delay the spread of smoke and flames in the event of a fire.

Installation Tips

Blue60 fire-rated expanding foam is most effective when it’s installed properly. Following manufacturers’ guidelines and fire safety regulations during installation will help ensure the foam achieves its tested fire and acoustic performance.

For optimal results, Blue60 fire foam should be used in gaps that are between 3mm and 30mm wide. The foam should be applied to a clean, dust-free surface, and proper curing times should be observed. During installation, it’s important to use the foam correctly and to ensure the gap between the door frame and the structural opening is adequately filled.

When used according to the manufacturer’s guidelines, Blue60 fire-rated foam is able to insulate not only against fire but also sound, helping buildings to become safer and more pleasant places to be.
