Hello,
Background: We selected windows and roller shutters and received the dimensions from the company. Based on this information, the shell construction was built. When the windows and roller shutters were then ordered by the company from the manufacturer, it turned out that an old roller shutter model had been offered to us, which is no longer available. The new one is now 2 cm (0.8 inches) smaller. By that time, of course, the shell construction was already in place.
Now to my question: How do I close the 2 cm (0.8 inches) gap? I was advised to use Heraklith. From your point of view, is that correct, or is there another option?

PU foam is polyurethane, which is the material used in PUR insulation. No thermal bridgeHowever, the same amount of PU foam unfortunately provides slightly less insulation compared to PUR insulation (0.2–0.3 versus 0.3–0.4).

I have now discussed with my site manager that 6 cm (2.4 inches) of insulation wool from the external insulation will be installed there, and I would fill the remaining 1.5 cm (0.6 inches) with strips of the same wool. Furthermore, the roller shutter box is still 4 cm (1.6 inches) too thin to be flush with the aerated concrete (Ytong), so it can be plastered properly. The plastering company now wants to use Wedi boards instead of Heraklith for that. According to online sources, that shouldn’t cause any issues regarding insulation.
So, I’m done with the company through which we ordered the windows...
