Intumescent seals

[Guest Toby]

Can 15mm intumescent seals be installed on a standard size FD30 fire door blank. The label on on the top of the door is CF 807 but when I looked at this it’s suggests 10mm seals. The certificate only mentions maximum sizes so does that mean any configuration on the certificate can be used?

CF 807 available at  https://www.falconpp.co.uk/media/15948/cf807-falcon-panel-products.pdf    provides details of the intumescent seal requirement for various door configurations and seal types on pages 5 & 6 of the data sheet.  There is further technical data for Strebord fire doors and intumescent seal requirements at https://falcon-timber.com/downloads/
