Good morning,
we have a house from 1971 with ETICS (external thermal insulation composite system) – 5 cm (2 inches) insulation.
Our roof is a flat roof, which was renovated this year.
We would also like to renovate our facade at some point. I have read that doing so would require us to upgrade the insulation according to the Building Energy Act.
This would obviously mean considerable additional work, for example because the parapet, etc., would need to be renewed – it was installed on top of the 5 cm (2 inches) insulation.
Now, there is apparently the possibility to be exempted due to economic infeasibility in order to only renew the plaster, for example.
What are the chances of this? What is the best way to approach it?
It cannot be that you can renew the plaster for maybe around 10,000 euros but are then required by the Building Energy Act to insulate and pay three times as much including all related work – that cannot be financially reasonable! Are costs caused by additional work, such as renewing the parapet, included in the calculation of economic feasibility?
Best regards!

How can I check if the cracks go all the way through the external wall insulation system (EWIS)?How far can you insert a flat screwdriver or a piece of paper into the crack? After prolonged rain, do you notice any moisture stains forming around the cracks? These methods are only rough approximations. The only sure way is to carefully remove a small patch of plaster and take a closer look. You could also simulate rain using a garden hose.Only after that would I consider the next steps. But I don’t see a need to replace the entire facade.
