Spotting on EIFS

[mathew stouffer]

This appeared to be an EIFS or hybrid system. The spotting was only present on the east side. Any ideas what causes this. Home was built in 2000. One the south side I could see the joints between the foam panels.

Most likely a poor base coat and the edges of the foam boards were not rasped. The spots are the fasteners that were used to secure the foam boards.

One reason the spots show more on that side is that the base coat that is covering the fasteners was put on too thick and the moisture does not dry as quick in those areas.

What are the odds water is penetrating through that dish attachment...

Those vents look too close to that wall too - how far away are they?

Looks like the thermopane has failed, condensation between panes.
The round spots are the metal cleats fastening the foam board. The metal is a heat sink, they sit on the top of the foam.

The more I read and see about this stuff and the miilion details to install it why is it still being used.

Very few brands ever used metal, the vast majority used plastic.

Thanks Scott,

I have seen metal used as well as plastic.

Raymond,

not sure where that link is supposed to go?

Would a thermal scan of that siding be a good method of detecting 'what lurks behind' the surface.
