Are Synergised balcony boards compliant with UK high-rise building regulations?

Yes. Synergised® aluminium balcony boards achieve Euroclass A1 and A2-s1,d0 / A2fl-s1 fire ratings when tested to EN 13501, EN 13823, and EN ISO 1716 standards. This meets UK legal requirements restricting combustible materials on residential high-rise balconies.
