Hi Vince,
Thank you for your question.
A 12mm hearth can be used when a stove is fitted without a fireplace around it, in an open plan room.
In order to use a freestanding stove with a 12mm hearth made of glass or slate, the stove must not cause the temperature of the upper surface of the hearth to reach or exceed 100°C

The Tiger could reach these high temperatures and so a "constructional" hearth is required.
If you are fitting the stove into an existing fireplace you will more likely than not already have a constructional hearth.
The full details are listed in page 37 of the current Building Regulations Part J document ( https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/468872/ADJ_LOCKED.pdf )
Hope this helps? If you need more information please feel free to call us on 0845 450 8351
Kind regards,
