Looking for low U factor with high SHGC windows?
Give the window company a call directly. I was ready to give up and order the standard low SHGC windows offered by everyone when I decided to call up Gerkin (midwest company) and ask them about their coatings. I talked to a nice lady who told me they get their coatings from Cardinal and that the 366 coating is the one they use. When I asked if I could get the 180 coating on some windows she told me that if it’s a current Cardinal coating that they can get it. This made my day as nowhere in their printed literature or online do they give any coating options (other than clear or LowE).
Hopefully other window manufacturers will be as accommodating.
