Is it possible to get sliding internal fire doors that meet Building Regs approval?

[soberton]

Just that really, I wondered if sliding fire doors actually exist for normal domestic properties, only for one doorway in particular (about 76" high and 28" wide), which are approved by Building regs.
If so, could anyone recommend any uk stockists?
Many thanks

We used eclisse pocket doors for our loft conversion to max out the space. They are so amazing, but it does form part of the wall - don't know if you're building a wall or just want to replace the door.

The proper fire door frame costs about twice that of the normal sliding door frame and I don't think the building inspector asked questions - he just checked that it slid all the way in to form a seal.
