Fire doors with glass panels

I have to get fire doors (FD20) in my house to comply with building regs as I am converting the attic. I would like the ground floor ones to have glass panels but it seems the glass would have to have wire in it (yuk!).
Does anyone know where I can get glass panel fire doors without wire mesh? Have seen on web but only in America.

Most suppliers seem to use [broken link removed] or [broken link removed]. The doors on the Deanta website with an asterix next to the name/desc are fire doors. These are readily available in most builders providers - ie McMahons, etc.
