Does a concrete lintel need any additional fire protection?

[MikeGrahamT21]

As title really, I’m used to steel lintels requiring additional protection in the form of plasterboard, but do concrete lintels need the same or can I just go straight in with bonding coat?

 

Thanks!

Most of the standard lintels are rated 30 mins but you can get higher fire ratings.

You will find that a bonding coat will also add some fire protection Ideally you will mesh where the lintels are

From memory the new one was from the economy range and the existing one on the inner leaf is absolutely huge, so if that’s the case then both will be min 30mins.

 

@nod What kind of mesh will I need for the job? Expanded metal?

 

Thanks
