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.
BM TRADA Q-Mark Fire Door Manufacturer scheme provides reassurance that our fire doors are fit for purpose through on-going compliance to the original product specification. This provides peace of mind that the products are manufactured to a consistent quality through independent verification by a third-party certification body.
Demonstrating that our fire doorsets meet stringent security standards and are manufactured to a consistent quality, the BM TRADA Q-Mark Enhanced Security Door scheme supports the testing requirements for Secured by Design (SBD), reducing crime on housing developments by incorporating crime prevention measures at the design stage.
Our FD30 and FD60 doorsets are certified by Secured by Design. Membership to the SBD scheme was made possible as a result of the our internal fire doorsets meeting the strict set of criteria set out in PAS 24 Enhanced Security Doors.
Certifire brings confidence to our customers, helping to inform their decision when purchasing a product. The Certifire brand is recognised by regulatory authorities worldwide as a mark of fire safety. Choosing a fire doorset that carries such a reputable third-party certification gives assurance as to the performance.
