If you’ve ever worked the trades and around these people.
Reality is many “no habla nada”. Education under third world conditions is a luxury, not a necessity, many cannot afford.
They are plying some labor efforts as soon as they can walk on their own and assist the rest of the family in some way.
Not unlike what rural America was and still is in some regions.
In the Building Science IR Class we were told that Tyvek must not be installed upside down or it will not work as designed, chemical exposure (from nails) also degrade it.
And the tyvek reps in the KC metro will tell you no matter right side left side inside out side it does not matter it will still work!
Thanks, folks.
I think there should be a drip cap on top of the window trim, but the builder is not of the same opinion. Will advise buyer to keep maintained.
You must go to a good source of specs and compare the permeability of Tyvek, Typar and tarpaper. I think you will find that Tyvek is by far the more permeable and able to let the moisture “breathe” (proper term is “diffuse”) out of the wall.
From a report I did for an architect in a code ruling last fall:
“The new walls have Typar as the sheathing membrane versus 15 lb. tarpaper. The permeability of the Typar is 11.7 perms versus 8 perms for the tarpaper. Although the Typar is slightly more permeable than the tarpaper, it is in the same order of magnitude and not a number of times more permeable than a product such as Tyvek at 58 perms”
Linda, I agree there should be a cap flashing. In my area the majority new construction homes you do not see cap flashing anywhere. I recently just started noting it in my report although it seems like a waste of time. The flashing below the window trim near the window should not be caulked .
