Hello,
we have received the building permit / planning permission for our house.
The exterior wall is planned to be 24cm (9.5 inches) Poroton brick plus 14cm (5.5 inches) external thermal insulation composite system (ETICS).
More and more people are advising me against this, but using a 36cm (14 inches) brick would have been too expensive (and the construction company probably wouldn’t agree).
Now I am considering switching from polystyrene to stone wool insulation – is this still possible?
Is polystyrene really as bad as some claim, or can it still be acceptable?
Thank you very much in advance.
