Shadbolt security doors can also provide excellent fire resistance, smoke control and acoustic performance, combined with good mechanical strength and dimensional stability.
Doors have been tested to BS 476: Part 22 in a wide range of configurations and sizes, and can provide 30 minutes or 60 minutes fire resistance (FD30 or FD60).
Fire performance is assured by ongoing independent third party certification by Exova BM TRADA Q-Mark UKAS-accredited certification scheme, or an equivalent..
Authoritative assessments can be provided for variations from a tested door design.
Where required, doors can be fitted with seals to resist the passage of smoke at ambient temperature.

Shadbolt security doors can achieve a Severe duty classification, the highest possible, to EN 1192 Doors - Classification of Strength Requirements and EN 1191 Windows and Doors – Resistance to Repeated Opening and Closing.
The Severe rating enables the doors to be used in the most demanding applications where they are likely to be subjected to frequent use and abuse
