The commitment towards protecting both people and buildings from fire takes Nullifire, a brand of CPG UK, once again one-step further in its fire stopping product offering, with the launch of a new safe space to stop fire spread!

Cavity barriers have been in high demand due to their role and importance in safeguarding buildings. Cavity barriers are passive fire protection products made of fire-resistant materials, they are used to seal cavities and therefore, prevent the spread of flames and smoke through spaces within the cavities of the building.

This process slows the spread of a fire, increasing the time people are able to evacuate the building and allowing the fire fighters to get the fire under control on a faster time frame, thus reducing the damage to the building.

New to Nullifire’s fire stopping product portfolio is the following diverse product range:
o FJ260 Cavity Barrier
o FV025 Small Ventilated Cavity Barrier
o FV050 Small Ventilated Cavity Barrier
o FV125 Large Ventilated Cavity Barrier
o FV225 Large Ventilated Cavity Barrier
o FV144 Large Ventilated Cavity Barrier
o FV065 Small Ventilated Cavity Barrier Roll

FV025 and FV050 are ventilated cavity barriers suited to open state cavities of up to 25 mm and 50 mm, offering up to 60 and 120 minutes fire resistance. Their unique graphite expansion technology provides directionality and a high expansion ratio, with low smoke and zero halogen intumescent components.

Also, part of the range is FV125, FV225 and FV144; the large ventilated cavity barriers. These are a specially formulated fire rated mineral fibre with an integral high expansion intumescent seal attached to the leading edge. For cavities up to 450 mm, these can offer up to 180 minutes fire resistance tested in accordance with ASFP TGD19 Guidance.

FV065 is a cavity barrier roll designed to firestop cavities up to 65 mm behind external walls. Suitable for masonry and brickwork external substrates, its roll format allows for space and labour savings.

Lastly, FJ260 Cavity Barrier, is the non-ventilated fire barrier within the range. This product is used for vertical external wall cavities and can achieve up to 120 minutes fire resistance.
These products are the only product range that has testing with SFS (steel frame system) systems.

These new additions represent an important step in Nullifire’s approach to supplying the complete fire stopping solution, which help support the increasing demands for supply chain efficiencies and certified fire protection solutions.

Nullifire’s Sales Director, Gary Pullinger, states "we continue to build the Nullifire brand and in line with other CPG brands, offer complete solutions for the external envelope of a building”.
Nullifire’s technical support teams across the UK will be available to provide guidance and answer technical enquiries.

Manufactured within the UK, these new Nullifire products have been tested extensively by third party test houses and fully certified for a range of fire protection needs.

Part of the Construction Products Group portfolio of brands, Nullifire products are used extensively across built environments alongside some of their sister brands’ such as illbruck, namely for façade systems. Their single source approach guarantees highly knowledgeable technical support and service teams with a proven track record of performance and compliant systems, to ensure the ultimate peace of mind in the specification process.
