Northern Ireland-based company Heron Fire Doors – part of Heron Manufacture Ltd – is poised to shake up the market for fire doors with the launch of an innovative new doorset engineered for next-gen energy efficiency.

Developed over two years, Thermasafe 30™ delivers outstanding fire and smoke resistance. It also offers advanced thermal, acoustic, and security performance, with an industry-leading U-value of just 1.2W/m²K. Weather resistance comes as standard – all in a sustainably sourced, cost-effective package.

Raising the bar on fire doors

Representing a new benchmark for fire doors, Thermasafe 30™ is built around an innovative engineered timber core that delivers a U-value of 1.2W/m²K, making it up to 30% more thermally efficient than conventional timber fire doors.

Enhanced weather seals, thermally bridged thresholds, and draught-resistant ironmongery options contribute to significantly reduced heat loss and improved energy efficiency, supporting greener construction and lower running costs.

The product’s advanced green credentials combine with elite fire and smoke resistance that sees Thermasafe 30™ consistently exceed FD30s and E30Sa standards, achieving 45 minutes of fire and smoke-stopping performance.

Unlike foam or composite-based alternatives, Thermasafe 30™ is made from recyclable, sustainably sourced timber, offering specifiers a future-proof solution with reduced environmental impact and a manual handling-friendly design. It’s already an award-winner, having scooped the BWF’s Award for Innovation in 2024!
