Most highly accredited passive fire protection system in the market understanding BS and EN regulations
Designed to meet the most stringent fire safety requirements in the building industry, the fire-rated duct system has been comprehensively tested by Exova Warrington-fire research department, achieving 245 minutes – the highest fire rating achieved by a ventilation duct. SAFE 4 fire rated ductwork system has been developed aligning with the British Standards BS 476 part 24 and European Standard EN 12101-7 for smoke extract and EN 15871 for fire ductwork, kitchen extract and pressurization.
Strictest procedures in manufacturing, installation and inspection are adhered to and certification is provided by trained inspectors on completion of the project.
PERFORMANCE CRITERIA
Integrity:
Complete smoke management system based on the performance of all elements from penetration seals to smoke leakage and to cross sectional area.
Stability:
- Leakage is set to different parameters for smoke extract and fire rated duct
- Smoke extract is tested to a maximum of 10m3/hr/m2 and a low of 5m3/hr/m2
- Fire duct is tested at a higher rate to a maximum of 15m3/hr/m2 and a low of less than 10m3/hr/m2
- SAFE 4 received a classification of “S” in both tests; “S” being the highest classification in this category
SAFE4 i – up to 3 hours insulation
- Ductwork offers insulation of up to 3 hours at 1200⁰C. Thickness and density is calculated by the type of system and time period required
- Its insulation is a compact calcium magnesium silicate blanket made from low bio-persistence wool with a thickness of 38mm
- It has a resistance to both thermal shock and mould growth (anti-microbial) ideal for hospital applications
