“Fire precautions in the design and construction of buildings”.
BS 5588 is a British Standard, and an Approved Document for compliance with the Building Regulations (England & Wales).
This Document addresses the need for sealing the threshold of a fire resistant door assembly, stating that if the gap at the threshold exceeds 3mm, then a threshold seal must be used.
