Here at Adexon, we design and manufacture the UK’s premier fire curtain systems. Every product we create is engineered to solve the real-world reliability issues that have challenged this industry for decades.
Our mission is simple: significantly improve the real-life performance of fire curtains. We go far beyond outdated standards to deliver systems that meet modern expectations for safety, reliability, and long-term peace of mind.
Our Background
We’re part of the Cubex Group, which has worked with fire curtain systems for nearly 20 years. For a long time, this market was seen as niche and lacking potential. It also demanded serious investment to bring about any real innovation.
That changed for us over seven years ago. Major contractors across London began encouraging us to focus on fire curtains, recognising our track record in complex engineering through our high-security projects. One standout example is the US Embassy in London, where we designed and manufactured 4-tonne high-speed vehicle gates clad in 10 inches of glazing, operating at double the normal UK/EU speed under special waivers.
Even while working with legacy fire curtain designs, we secured several large-value projects, including numerous six- and seven-figure contracts. That was a clear signal, demand for better reliability and performance was growing fast.
Fire Curtains, Redefined
We identified what we believed to be the core issue behind poor fire curtain performance. With that insight, we built an entirely new product line from the ground up.
Our systems are not only a technical leap forward, but they’re also backed by a 10-year warranty. We focus on industry-leading reliability, robust third-party certification, and real-world performance that meets today’s highest safety standards, without compromise.

Leading with Innovation
We now offer the UK’s widest range of third-party certified fire and smoke curtains, and we’re just getting started. Our ongoing investment in R&D has already led to several UK firsts:
• S200: The UK’s first elevated-temperature smoke performance test. Read why it matters: Are cold smoke seals in fire curtains a cause for concern?
• 16m x 10m EI120 ‘dry’ fire curtain on a single barrel, with S200-level smoke performance. Typically used with sprinkler systems, this represents a modern step-change in system capabilities.
• Concertina fire curtain certified to BS EN 1634-1 and BS EN 12101-1. This is the UK’s only scope-compliant, dual-certified fire and smoke curtain.
• Horizontal fire curtain up to 20m x 10m without support cables. Larger sizes available with cable support.
• Deployed pressure testing on vertical curtains over 100 Pa.
• C2 cycle testing: 10,000+ cycles completed on multiple products. No competitor has achieved similar results.
Designed for Ambitious Architecture
We believe safety should never limit design. That’s why our systems help architects push boundaries while staying fully compliant with the most demanding standards.
Every fire curtain we supply is:
• Fully compliant with the latest EN Standards.
• Independently tested and certified.
• Designed for high reliability and large-scale use.
• Backed by our 10-year warranty.
We’re here to support architects, contractors, specifiers, fire engineers, and other industry professionals in delivering safer, future-ready buildings. If you’re specifying fire protection systems, we’ll help you raise the bar.
