I'm pricing a job where the render finish has failed on phenolic insulation,it looks like they have used a sand and cement render!!!im removing a piece today to b sure.they want me to remove the whole system including rails n boards.is there anything on the market that I can use to bond the surface providing I remove any loose materials ect and put thin coat over the top???im happy to remove everything and start again tho it seems like it's gonna b hard to remove the insulation without a lot of mess and a waste of money!thanx

Alot of manufacturers will not warrant phonolics now because of failures.
Once wet they are no good. Im pretty sure remiving render only wont be any hood mate

I would recommend taking the whole thing off mate, including the Phenolic board.
As @Dansouthcoast84 says, lots of manufacturers wont warrant Phenolic boards for failures.

It can be any size you want.
Typical install is 90mm.
I have had build regs say 50mm is acceptable upgrade in insulation
it depends on the thickness of substrate, you cant just guess at it as to what thickness to use.
if its 50mm phenolic then your going to need a thicker eps to get to building regs arnt you, that's he benefit of using phenolic you can use a thinner board to get u value.
to get regs of 0.30 you can use 90mm eps, if its a single skin your going to be more.
