Exterior Insulation and Strapping

Here's the reason why dumb contractors are a mouse's best friend.

First, a little background.  The exterior of the house was insulated with foam insulation.  When you hear that the walls of the house have been upgraded to exceed code by having exterior insulation applied to the walls, your first thought is "Wow!  That's fantastic!!"

With a little bit of investigation your initial "Wow!" factor quickly turns into an overwhelming sense of WTF!? 

Check this out.  Exterior foam insulation was installed and then strapped with 1x3 spruce strapping.  Umm, to me it's pretty obvious something is amiss.  

Need a clue?

It's the writing on the wall - it's sideways.

The manufacturer's installation instructions simply state:

• Tongue and groove (T&G)edge panels install horizontally.
• Fit joints tightly.

Well, the manufacturer is pretty clear on how things need to be done.  Install the panels horizontally and fit the joints tightly. Never mind the nailing pattern which is completely botched as well, or the fact the joints remain open and untaped.

Like, how dumb is the contractor? How blind or ignorant was the homeowner who hired the dumb contractor?

All of this indicates this energy retrofit is a major fail because the dumb contractor did everything they could to screw it up. The ignorant homeowner didn't read the writing on the wall, nor did they take the time to educate themselves about how the product they purchased should be installed either.

Then we have the strapping installed by the dumb contractor and how this dopey dude became the best friend a mouse could ever hope for.

Here's a corner detail.  Strapping is installed so it creates a raceway from the bottom to the top, with a convenient means to gain access to all parts of the wall, behind the siding and parts beyond.

See that wee hole? That's a hole chewed by a mouse.

Oh, and don't get me started on the golf towel used to "fill a gap" in the insulation. Of course it made a great home for the mice.

I hate mice, but I hate dopey dumb contractors even more.
