I understand the advantages of using “outsulation” (rigid insulation on the outside)
I am still having trouble finding satisfactory details.
Especially concerning Window head details used with siding.
I went for the pro account here at GBA and started looking at the details.
I still wonder if anyone has actually constructed these details to see what they will look like and how they fit together.
It looks to me like the head details show the water draining behind the window trim(casing) and somehow magically weeping out between the bottom of the casing and the flashing.
If you imagine the intersection of the Head detail with the jamb detail… what you get is certainly not the traditional “look” of a cased window….here is a photo of what I assume the GBA detail would look like..
(photo taken at a Peter Pfeiffer project in Austin)
Not only does this look bad…But I think the flashing is in the wrong place.
Any weather/water that gets past the siding and hits the weather barrier should be diverted to the outside ABOVE(not below) the casing that caps the window. That’s how they did it in the old days.That’s why the photo does not “look right”.
Is it just me?
