Certification

Sentry Doors back for third consecutive year at the Fire Safety Event 2024 Read more…

We pride ourselves on continually demonstrating commitment to the highest standards of construction practice. Evidence can be found in the certification and accreditations we hold.

Designed to offer peace of mind, our FD30 and FD60 doorsets undergo independent testing and approval from BM TRADA and Certifire standards. Both are certified by Secured by Design and we are one of the few companies nationally to have achieved dual certification (Q-Mark Fire Door Manufacture and Q-Mark Enhanced Security) for both our FD30s and FD60s flat entrance doorsets

This, together with continued investment in product development and testing enables us to offer a wide choice of certified fire doors.
