Does plastic covering for fire doors affect rating?

[Guest Wilding]

Hi Team.

Could you please help with a query re covering some commercial property 30 min fire door faces with a thin self adhesive sticky plastic. The company that make this are d-c-fix but unfortunately they do not specify if its suitable for fire doors except they say due to its 1mm thickness it will not affect the rating. I have spoken to the local Building Control but they only deal with alterations.

Any help would be appreciated.

Thank you Mark

Fire door leaves are generally not required to provide a specific surface spread-of-flame barrier, and may therefore be decorated as desired. It is recommended in BS 8214 2008 that overpainting be limited to a maximum of five coats of conventional oil-bound paint or varnish. Based on this, 1mm of plastic covering is not going to serious effect the fire door.
