ᐅ Experiences with Exterior Insulation and Finish Systems (EIFS) from Different Manufacturers?

Hello everyone,

I have the following situation. In my new build, the facade was insulated with mineral wool. Now I realize that the adhesive mortar used is suitable for mineral wool but comes from a different manufacturer. I have read up on it, and usually all components should come from the same manufacturer or system and not be mixed.

Does anyone have experience with this?

What options are available now?

Thanks for your input

Of course they should – otherwise one manufacturer would capture the entire profit margin.

Do you also use only oil from your car’s manufacturer (who doesn’t actually produce it themselves any more than the drywall company produces the adhesive mortar) or do you use other suitable oils?

Exactly...

Yes, you’re right, and I know that too.

So, what options are there now?

If you don’t stay within an approved system, there is formally no permit for the system. That means no warranty from the system manufacturer and also no realistic building authority approval. It must formally be demolished.

To use a car analogy: you have just installed fake, possibly non-functional brakes from China without roadworthiness certification and CE declaration.

Options? Talk to the company and ask to see the approvals. Talk to the manufacturer of the mineral wool boards.

Warranty is at stake here. The manufacturer will most likely always deny responsibility, claiming the wrong mortar was used.

It’s ultimately about the warranty. In case of doubt, the manufacturer will ALWAYS deny responsibility because they claim the wrong mortar was used.

Would an extended warranty, for example 15 years, be an option?

First, talk to the company and the system manufacturer.

Will the company still exist in 15 years? That wouldn’t be a good compromise for me.

Honestly? This system stuff is just a way to make money in the end. If everything is properly glued and doweled, it really doesn’t matter what was used. The problems almost always come from poor workmanship, not bad materials.
