Hi Guys,

Looking to use 75mm PIR board for EWI, not able to use anything else due to soffit overhang & U value, without altering roof line.

Question is can I render onto PIR boards as you know they are foil covered. If so what can I use.

Thanks in advance for any advice :)

Thincoat render.
Weber LAC base coat is my go to but others are available.
You’re looking for synthetic polymer thincoat.
Pick a product and be sure to speak to the technical support beforehand.
