About Us

Born from decades of automotive expertise, Fire Cloak™ exists to protect people, assets, and businesses from the risks of lithium battery fires.

Fire Cloak™ was born out of Prosol UK — a trusted supplier to the automotive sector since 1991. When electric vehicles became mainstream, we saw the growing fire risks posed by lithium batteries. Drawing on decades of technical and industry experience, we developed the UK’s first purpose-built fire limitation blanket.

From day one, our goal was clear: To create the most advanced, most reliable fire containment solution on the market. We weren’t prepared to compromise on materials, testing or performance — and we weren’t prepared to rely on imports with long lead times, dubious quality, or inflated costs.

Instead, we committed to building Fire Cloak™ in the UK. Working closely with leading fire-resistant textile manufacturers during the design and concept phase, we established the specifications and performance standards needed to outperform anything else on the market. From there, Fire Cloak™ became a UK manufacturer in its own right — designing, testing, and producing a blanket built to the highest levels of quality, reliability, and safety.

What makes Fire Cloak™ different?

  • UK designed and manufactured — we are proud to support British industry, offering customers flexibility, speed, quality, and transparency.

  • Rigour, testing and quality — Fire Cloak™ is tested against a wide range of international fire resistance standards to ensure it delivers maximum protection. Alongside this, we run a continuous programme of review and refinement — making sure the product not only meets today’s demands, but also keeps pace with advances in technology and emerging risks.

  • Verified and transparent — every claim we make can be backed up. Fire Cloak™ is manufactured under ISO 9001 controls, with fire resistance testing carried out by respected third-party organisations. Certifications are published and available for scrutiny, so you can be confident in both the product and the process behind it.

  • Certified performance — Fire Cloak™ is certified to DIN SPEC 91489:2024-11, the world’s first standard for EV fire limitation blankets.

Behind the technology is a team with deep credibility.

  • Andy Coulton (Managing Director) — Polymer Technologist with a career in automotive safety products, leading product development and engineering.

  • Mark Tamblyn (Sales Director) — customer-focused, with senior automotive leadership experience at Brand Director level.

  • Matt Butcher & Jack Bryson — Product Specialists, both with General Management experience in franchised dealer networks.

Together, we combine technical expertise and commercial insight to deliver solutions that truly protect.

Our purpose is simple: Fire Cloak™ exists to protect people, assets, and businesses from extreme fire events.

Every blanket we produce is about giving our customers confidence, control and continuity.
