CB-NV Fire Cavity Barrier Singapore \u2014 Quick Facts<\/h2>\n

The CB-NV Fire Cavity Barrier<\/strong> is Two Nine Six O\u2019s (T2960) 240-minute fire-rated, non-combustible stone mineral wool barrier for fa\u00e7ade and floor cavities. As the fire cavity barrier Singapore<\/strong> contractors specify most often for commercial and residential fa\u00e7ades, CB-NV pairs proven RCS fibre technology with a moisture-resistant water-shield layer. Consequently, it performs reliably even in humid, non-ventilated tropical conditions. Because Singapore\u2019s building codes demand rigorous passive fire protection, explore our full fire protective systems range<\/a> alongside CB-NV to specify a complete solution.<\/p>\n

Product Description<\/h2>\n
\n

A proven fire barrier for fa\u00e7ades and floors<\/h3>\n

The CB-NV Fire Cavity Barrier<\/strong> uses non-combustible stone mineral wool<\/strong> to stop fire spreading through wall and floor cavities. Moreover, it holds a Non-Combustibility Rating and keeps its fire-resisting performance even in non-ventilated conditions<\/strong>. In addition, a fire-retardant water-shield layer<\/strong> protects the barrier from moisture exposure.<\/p>\n

How the RCS technology works<\/h3>\n

Two Nine Six O makes CB-NV with exclusive RCS (Rapid Centrifugal Spinning)<\/strong> technology. Specifically, this process creates a very thin, even fibre structure that thermosetting resins and water repellant bond together. Furthermore, the proprietary Pendulum System<\/strong> builds thinner air layers inside the barrier, so it blocks heat flow more effectively.<\/p>\n

Performance and ease of fit<\/h3>\n

As a result, CB-NV delivers fire integrity for up to 240 minutes<\/strong> in both vertical and horizontal cavity positions. In practice, it fits cavities up to 600 mm wide<\/strong> and needs only a simple friction-fit<\/strong> \u2014 no adhesives or special tools required.<\/p>\n<\/div>\n

Key Benefits of the CB-NV Fire Cavity Barrier in Singapore<\/h2>\n
\n
\n

\ud83d\udd25 Up to 240-Minute Fire Integrity<\/h3>\n

Notably, independent labs test CB-NV to BS 476: Part 20 in both vertical and horizontal positions. As a result, it gives proven, long-duration fire compartmentation for fa\u00e7ades, floors, and walls.<\/p>\n<\/div>\n

\n

\ud83e\uddf1 Non-Combustible Stone Mineral Wool<\/h3>\n

CB-NV passes the BS 476: Part 4: 1970 non-combustibility test. Moreover, Two Nine Six O makes it from inorganic stone mineral wool \u2014 not an intumescent foam or flexible sealant.<\/p>\n<\/div>\n

\n

\ud83d\udca7 Moisture & Weather Resistant<\/h3>\n

Additionally, a fire-retardant water-shield layer covers CB-NV, so humidity does not change its performance. Furthermore, it resists vermin and fungi for long-term durability on site.<\/p>\n<\/div>\n

\n

\ud83c\udfd7\ufe0f Versatile Fa\u00e7ade Installation<\/h3>\n

For example, you can use CB-NV in floors, walls, raised floors, external fa\u00e7ades, and weather features. In addition, test teams have checked it with masonry support brackets for complex curtain wall systems.<\/p>\n<\/div>\n

\n

\u2699\ufe0f Simple Friction-Fit Installation<\/h3>\n

No adhesives needed. Instead, you press CB-NV onto galvanized impaling L-clips at 450 mm centres. In addition, it fits horizontally or vertically, so it reduces installation time on site.<\/p>\n<\/div>\n

\n

\ud83c\udf3f Zero Harmful Substances<\/h3>\n

CB-NV contains zero HCHO, zero TVOC, zero Global Warming Potential, and zero Ozone Depletion Potential. It is also 100% asbestos-free, so it is safe for occupants and the environment.<\/p>\n<\/div>\n<\/div>\n
