Injectaclad’s first post-acquisition order: fire safety and retrofit notes for engineers
Reviewed by Tom Sullivan

First reported on The Construction Index
30 Second Briefing
Injectaclad has secured its first post-acquisition order following Light Science Technology Holdings’ April purchase of manufacturer RLUK Injection Ltd, supplying about £0.41m of its fire-resistant graphite barrier system to a five-storey residential block in East Yorkshire. The 19-week project, starting in early May 2026, will use Injectaclad to reinstate missing or damaged passive fire protection without full façade removal. LSTH now operates as both installer and supplier, leveraging a network of 11 approved installers and increasing specification in building safety regulator applications.
Technical Brief
- RLUK Injection Ltd, the system’s manufacturer, is now owned by Light Science Technology Holdings (LSTH).
- Material is being supplied to one of 11 approved Injectaclad installers operating within LSTH’s network.
- Installation is targeted over a 19-week window, implying phased access and sequencing around occupied residential units.
- Use of an injectable PFP system avoids full façade strip-out, reducing structural disturbance and temporary works requirements.
- Growing inclusion of Injectaclad in building safety regulator applications indicates formal acceptance of the system’s compliance role.
- For other high-rise remediation schemes, similar injection-based PFP reinstatement could materially cut capex versus full façade replacement.
Our Take
The reference to 11 installers in the Injectaclad network signals that scaling beyond East Yorkshire will likely hinge on expanding approved applicators; in our coverage of other fire safety products, limited installer capacity has often been the bottleneck to capturing post-Grenfell remediation demand in the United Kingdom.
