CastleForms today announced that its groundbreaking ICF FireBlock (patent pending) system has officially achieved NSAI Certification from the National Standards Authority of Ireland – marking another major milestone in what has already been a landmark year for the company.
The certification follows the successful launch of ICF FireBlock and its recent recognition at the Irish Building and Design Awards, where the ground-breaking system secured the highly competitive Innovation in Construction Products Award.
“Achieving NSAI Certification is a major milestone for ICF FireBlock and a significant validation of the work our team has invested in developing a safer, more visible fire-stopping solution for the construction industry,” said Tom Maher, Director of CastleForms. “From the outset, our objective was to create a system that not only improves fire safety performance but also makes compliance easier to demonstrate and verify on site. The combination of independent certification, extensive fire testing and industry recognition gives our customers confidence that ICF FireBlock delivers exactly what modern construction demands – safety, simplicity and reliability.”
NSAI Certification provides independent verification that ICF FireBlock meets rigorous Irish and international standards for quality, performance and compliance. The certification offers architects, specifiers, contractors, fire consultants and building inspectors greater confidence in the system’s effectiveness while supporting streamlined regulatory compliance across residential and commercial developments.
A New Standard in Fire Protection for ICF Construction
Developed as part of the ICF Therm product range, ICF FireBlock has been specifically engineered to address one of the most significant challenges in modern insulated concrete formwork (ICF) construction – delivering reliable, verifiable fire-stopping throughout a building’s structure.
The patent-pending system incorporates high-density, non-combustible A1-rated mineral wool directly into standard ICF Therm blocks. Installed at designated fire-stopping locations within the wall assembly, ICF FireBlock eliminates the need for concealed or retrospective fire-stopping measures, creating a safer, more transparent and more easily inspected construction process.
The system is available in multiple configurations to accommodate external walls, internal party walls and stairwell enclosures, helping projects achieve robust compartmentalisation strategies across a wide range of applications.
Key Benefits of the NSAI Certified System Include:
- Independent NSAI Certification backed by extensive fire testing
- Enhanced support for compliance with fire safety regulations
- Integrated high-density mineral wool fire-stopping within the ICF Therm wall system
- Fully visible and verifiable installation throughout the construction process
- Elimination of hidden or post-installed fire-stopping measures
- Reduced risk of defects associated with poor workmanship or restricted site access
- Multiple configurations for external walls, party walls and stairwell applications
- Designed for installation simplicity on site
