ᐅ After installing the external thermal insulation composite system (ETICS), the roller shutters are rubbing against the housing.

Hello everyone,
The renovation of our small house is steadily progressing, and we are getting closer to moving in. Unfortunately, we have now encountered our first real setback—actually, the first problem that is causing me some real headache. Since the plasterer applied the external wall insulation system (ETICS), some of the roller shutter slats have started to rub against certain windows. Unfortunately, the entire house has already been fully plastered and painted. Here is a summary:
Now the window installer and plasterer are somewhat half-heartedly blaming each other:
Can anyone tell me who is responsible for fixing this defect?
And does anyone know if there is a minimum clearance that should be maintained between the slats and the box?
Thanks and best regards from the Southwest Palatinate

The renovation of our small house is steadily progressing, and we are getting closer to moving in. Unfortunately, we have now encountered our first real setback—actually, the first problem that is causing me some real headache. Since the plasterer applied the external wall insulation system (ETICS), some of the roller shutter slats have started to rub against certain windows. Unfortunately, the entire house has already been fully plastered and painted. Here is a summary:
- New Schüco uPVC windows with Lakal roller shutter boxes
- Windows including the roller shutter boxes were installed flush with the exterior wall to avoid deep reveals after applying the ETICS
- To do this, the concrete sills were cut out, so the ETICS was applied directly onto the roller shutter boxes
- The plasterer used a transparent adhesive suitable for plastics (Powerfix?) and pressed and tapped firmly during installation, similar to applying facade adhesive
- The problem now: The ETICS adhesive pushes the roller shutter box inward in the middle (the wider the window, the worse), causing it to rub against the slats in some areas
Now the window installer and plasterer are somewhat half-heartedly blaming each other:
- The window installer says the plasterer damaged his work. When he left the site, the shutters did not rub, and the boxes were straight
- The plasterer, who is definitely a skilled company with continuous training and has otherwise done all work to our utmost satisfaction, says he has never seen this happen with ETICS before. I know he has insulated quite a few houses
- The plasterer complains that the window installer should at least have left a warning about this issue
- Technicians from Lakal were on site because a roller shutter motor was defective right after installation. They said it is common practice to wedge between the shutter slats and box when applying the ETICS to prevent deformation. According to the plasterer, he had never heard of this before
Can anyone tell me who is responsible for fixing this defect?
And does anyone know if there is a minimum clearance that should be maintained between the slats and the box?
Thanks and best regards from the Southwest Palatinate

Anyone else have a tip?If your contractors really make the problem your problem and cannot find a solution among themselves, it certainly helps to shift the issue back to the tradespeople. Write to each party involved stating that you do not agree with the defect and set a deadline for correction. Inform each of them that you will withhold a sum if the issue is not resolved. They can then dispute this with you or among themselves, or come to an agreement. I consider the latter most likely.

We are currently facing a problem. The window installer has already been fully paid, but there are still many defects with the facade company, and they have not yet issued a final invoice. About one third of the contract amount is still outstanding here.

BenjaminJ15 Sep 2021 21:40Good evening,
we were fortunately faced with a material defect in the reinforcing adhesive of our plaster system, which caused countless cracks in the house. The plaster manufacturer’s insurance took over, and the entire plaster was removed down to the external wall insulation system (EWIS) or, in uninsulated areas, down to the masonry. Since this allowed the issue to be properly addressed, the plasterer took great care during the re-plastering. The roller shutter boxes were wedged before applying the plaster to prevent deformation of the slats. This freed up 90% of the roller shutters, and where it was still too tight, the roller shutter boxes were actually adjusted again. Although our plastering company is good and the boxes unfortunately are really poor quality (easily deformable even with a little finger, impossible to plaster without deformation unless wedged), I believe that in the end it was their fault.
Another good sign: most of the roller shutters were fully operational again after the plaster and the adhesive boards on the roller shutter boxes were removed, without any sanding.
I wish you a lot of patience. From my experience, a letter from a lawyer often carries more weight than self-imposed deadlines 🙁
Best regards
Benjamin

Ruhrgebiet2315 Sep 2021 21:44Thanks for the response! That was quite a lucky coincidence, if you can call it that with all the trouble. ;-)
Yes, we already have some building experience, and this is not the first point of conflict... I also suspect the plasterer is to blame. The defect appeared on six roller shutters – if it had been like this from the start, surely not so many assemblies would have left the window company’s workshop...

Ruhrgebiet2316 Sep 2021 10:51Dear BenjaminJ, could you please explain again what a "Auskeiler" is and what you mean by "and the roller shutter box was tapered before applying the plaster"? It was probably not done like that in our case either...
