SHGC ? I want the heat to come thru in the winter.
I am confused about what type of glass will work for us. We are in the process of ordering Marvin INfinity windows but I am afraid of the glass options. The low e 272 is what we just ordered but it looks like the SHGC is .30. Does that mean no barely any heat is going to come thru the glass in the winter? We have anderson casement right now that are 21 years old and I can feel heat come thru in the winter and I like it because it is warm. Is there a good SHGC value to look at that will let some warmth come in?
