I notice fire door lining sets being sold in the shops, but I hear the lining itself is no different from a normal lining except a groove is pre-made in the timber for a intumescent strip so that it can then be called a fire rated lining.
In otherwords there is no difference in the timber, but as the term 'fire rated' is used it sort of implies the timber has in some way been treated with a fire retardant.
Can anyone confirm ?
