Reveal insulation strips on windows - replacement necessary?

Hello,

I have a question about reveal insulation strips or wall edge strips at the window reveals. We have a double-shell masonry with a construction of about 45 cm (from outside to inside):
- 17.5 cm Ytong
- 14 cm facade insulation (Rockwool Kernrock; 1x 6 cm thick and 1x 8 cm thick staggered on the wall anchors)
- approx. 1-2 cm air layer
- 11.5 cm clinker/veneer (Röben hand-formed brick)

The windows will be installed on the inner rebate (clinker). At the reveals of the wall corners/windows, air-layer-limiting reveal insulation strips (extruded polystyrene, XPS) should be installed/glued. Since we have 14 cm facade insulation, the reveal insulation strips should also be 14 cm deep, right? Installed were reveal insulation strips with the dimensions 14x8 cm. The clinker has now been raised. We are getting 21 windows. At 4 of these windows, I have noticed that reveal insulation strips of 12x8 cm were installed! Accordingly, they are 2 cm too shallow. Apparently, the first package of insulation strips was empty and the wrong order was placed for the second pallet...

Upon initial inquiry with my general contractor, this was said not to be a problem since the windows will still be sealed airtight accordingly. Furthermore, it is supposed to be difficult to replace these insulation strips afterwards.

Now my actual questions:
- Is it bad that the insulation strips are 2 cm too short in depth? What should I expect?
- Does this affect the airtightness?
- Does this affect the insulation effect at the reveals?
- Can the insulation strips be replaced without removing the clinker again?
- Can I otherwise have a 2 cm layer glued on? (or is that shoddy work?)

If this is not to be seen as a serious defect, I would like to leave it as is, since I am afraid that the clinker would have to be torn off. The removal of the clinker at these points would cause a severe delay, since the windows are now supposed to be measured.

Thanks for your feedback.

Let pictures speak for themselves: where the bricks would have to be removed again, I am only not describing it textually.

First of all, I think it's nice that you have the bricks inside. It's something different!

As I see it, you now have a 3-4 cm air gap between the insulation strip and the bricks. Technically, this shouldn't be a disaster because, in my opinion, the airtightness is achieved through the sealed "inner connection."

If it were my house, I would still ask the builder to close the gaps. Surely this can be done with a compressible tape like VKP Trio.

Oops, of course the structure is from inside to outside!
I just went back to the construction site and re-measured, pictures coming up.

We actually have an air layer of 4 to 5 cm in the structure.
With the windows that have the wrong reveal insulation, this is even 7 cm at the window reveal!

By the way, we are getting Kömmerling windows with 88 profiles.

Should I be worried now?
I will call the site manager again tomorrow.

I was just back at the construction site and re-measured, pictures will come shortly.

I actually meant more in the direction straight at the gap, or a scan of the detailed drawing in the construction plan.

I am somewhat confused by the range of the gap between the masonry and the facing brick. That is between 12 and 18 cm, correct? At 12 cm the insulation is not as strong as you described. At 18 cm I would check whether the masonry ties are approved for the cavity width.
