I need to describe a disturbing recent event.
It was raining--not a hard rain, more like a steady drizzle. We were inside with the doors closed. I starting hearing water dripping, then saw water droplets coming out of the channel above the slider--through the holes above the INSIDE rear of the slider. I was absolutely horrified. The only source I could come up with was a leak in the roof seam above that spot.
I spent the night saying Hallelujah that I had used Thinsulate instead of polyiso or foam, but contemplating dismantling to remove the ezcool I wish I hadn't used. Contemplate: if there is a leak from above--be it seam failure or a leaking screw--with foam, polyiso, or ezcool, moisture could be trapped and could do a lot of damage before it made its way to a place where it would be discovered.
The next morning, I discovered that the slider was not completely closed. I'm guessing that moisture trickled in above the slider's top rail. I have not seen any moisture in subsequent rains.
Thinsulate is the only insulation commonly used here that will passively allow the moisture to escape, as it did in my case. If I had filled that channel with foam, the moisture would still be there.
