Additional endorsement of Injectaclad’s durability

• Enhanced product proposition
• Increased validation for potential customers

Light Science Technologies Holdings plc (AIM: LST), the innovative technology and manufacturing business providing real-world solutions targeting issues including global food security and fire safety, announces that following strenuous independent testing, the Injectaclad fire-resistant graphite barrier system, which is installed by the Company's Passive Fire Protection ("PFP") division, has been proven to have a 50-year lifespan - versus an industry barrier system average of c.15 years.

The Injectaclad solution, which the Company retrospectively installs within building cavities, was subjected to 153 days at 90°C-simulating a 50-year lifespan, with the results showing it maintained visual and structural integrity, with no degradation observed. The proven quality and longevity of Injectaclad provides further validation for building owners, residents, fire engineers, and regulators alike, with the Company primed to benefit from increased leverage as the UK's first independent approved installer of the system.

The rigorous testing, conducted to ASTM F1980 standards1, adds further value to the Injectaclad solution, and provides an additional USP - with the market looking for proven, cost effective and minimally invasive solutions to rectify non-compliant public and private buildings in the UK requiring cavity remediation. As regulations tighten and expectations rise, Injectaclad continues to set the standard for high-performance cavity fire barriers.

Chris Lewis, CEO of Injectaclad, commented: "This test further validates the robust performance of the Injectaclad solution over time. When lives depend on fire safety systems functioning decades from installation, this kind of data is non-negotiable. We're proud to deliver a product you can trust today, tomorrow, and 50 years from now. We recently awarded LSTH the Injectaclad Contractor Award and look forward to continuing our relationship with them."

Simon Deacon, CEO of LSTH, commented: "It's fantastic to have this additional qualification. We are focused on providing a cost effective and compelling solution to the regulatory-backed industry. Government targets will need to be fulfilled and we believe that the strength of our pipeline and ability to deliver increasingly large contracts to existing and new clients highlight the scalability and potential of this division. As the UK's premier independent approved installer, there is significant potential for us to add to our Injectaclad pump fleet and take advantage of the growing fire safety retrofit market in the UK."

LSTH IFB offers a practical and cost-effective solution to rectify non-compliant public and private buildings, spanning residential, commercial, and industrial sectors, with regard to fire safety regulations - a challenge addressed by a £6.1 billion allocation from the UK government. Serving as the UK's premier independent approved installer, LSTH IFB utilises the ground-breaking Injectaclad fire-resistant graphite barrier system. This system is retroactively installed within building cavities, reinstating fire-resistant performance and containing the spread of fire and smoke compliant with regulatory requirements. This innovative solution stands out as an appealing alternative to the more costly and disruptive method of removing external facades and installing traditional fire barriers. With a proven track record in the passive fire protection market and a robust sales pipeline, LSTH IFB targets a UK market potentially valued at up to £50 billion*.
