I’m on holiday so struggling to look this up and argue about it.
My architect wants us to have all the steel in our timber frame sent away to be sprayed with intumescent paint.
I cannot find the regs at the moment but it seems totally over the top in a two storey house.
He argues that just putting it behind fire rated board is not enough.
It would be a massive pain and expensive to do during frame erection.
Scottish regs apply. Any thoughts?
