Fire resistancePerformance
Doorsets provide 90 minutes (FD90) or 120 minutes (FD120) fire resistance.
They have been independently tested to BS 476: Part 22 in a range of sizes and configurations and with glazed apertures. Larger sizes and variations can be approved by means of authoritative assessments, as permitted by Approved Document B.
Copies of test reports and assessments are available.

Smoke control
Where required, smoke control doorsets (designated FD90S and FD120S) can be supplied fitted with seals to meet the performance requirement of Approved Document B to resist the passage of smoke at ambient temperature.

Acoustic performance
FD90 and FD 120 doorsets with suitable seals can provide significant sound insulation.

For information see Acoustic doors and doorsets.
