Integrity Only or Integrity and Insulation?

Integrity Only        xx/0 or Exx or ExxS

Integrity Only is a rating that restricts the progress of the fire through the fire rated fabrication. It does not offer any protection against the heat generated by the fire. Where the rating has an S suffix it offers protection against the passage of smoke. 

Integrity and Insulation    xx/xx or EIxx or EIxxS

An Integrity and Insulation rating not only offers the protection against the progress of the fire but also offers Insulation against the heat generated. As with Integrity Only where the rating has an S suffix it offers protection against the passage of smoke.

We can advise on which system has the rating that you need, but you would need to contact the relevant Planning Office to ascertain the rating you require in each situation as given in the Building Regulations Document B. Fire Resistant Integrity only doors are referred to as FD30(S) in the Building Regulations.
