Can I/how do I put glass into my fire door? Do I have to be an approved installer?
Not all fire rated doorsets can tolerate glazing and it is therefore essential to check the test evidence/assessment data for that door. If the door can accept glazing then it is of paramount importance that the exact guidelines are followed, as apertures may need to be internally framed/lined with timber.
The following is an excerpt from ‘A Guide to Best Practice in the Specification and Use of Fire-Resistant Glazed Systems’ written by the Glass and Glazing Federation (GGF).
‘The fundamental Golden Rule
Fire-resistant glass must only be used as part of a fire-resistant glazed system – which includes the glass, the glazing seal, beads, fixings and frame. All the essential components of such a system must be compatible under fire conditions, and the performance must be referenced to appropriate and relevant test evidence.’
There is currently no legal or statutory requirement to be certified to glaze fire-resisting doors. However, it is recommended that anyone undertaking this type of work attends an appropriate training course specifically on glazing, or at the very least a general course that outlines the construction of these performance products. Attendance will also help provide evidence that the installer is competent. (Suitable third-party certification can be obtained from a UKAS-accredited certification body).
