What is the best application of 1/2″ rigid foam insulation AND what is the best way to waterproof?
I am doing a project in Southern California where we have 1/2″ rigid foam called out on the exterior of the building to cut down on thermal bridging. I have done a good bit of research on my own but was not able to draw a conclusion about how to proceed due to the fact that there was so much argument between one type of foam and another. There was also a considerable amount of opinions on the location of the Water Resistive Barrier. Any Comments?
