Thanks Jerome J.

On pricing Fibertite has been very competitive. We prefer to specify 80 mil product as we've seen puncture problems at 45 mil, so if the Owner wants to downsize, going to 60 mil is still acceptable.

This requires a bit of tinkering with Part 2, since you're really specifiying two different products, with the typical clause "use one of the following two types."

We've used KEE membranes on a culinary school with 16 rooftop kitchen hood exhausts, with good results. We've also specified it as a flexible membrane flashing in some mod bit applications. I'd consider it a top of the line single ply.
