Hello, my contractor is going to use WIllmar ES2000 casement windows in our
new home. I am concerned about the SHGC. It appears the SHGC is .78, that
seems pretty high in compairison to other windows.
I live in ND so we do have harsh winters, from what I gather the higher the
SHGC the more heat the window collects. Other new homes around me are using
Marvin/Integrity/Anderson ect, those seem to have SHGCs around 35-40s.
I will be using the Solar Shield windows on the west side of my home, those
have a R4.1 and SHGC of 41.
Some advice would be appreciated. Is this a quality window? Is the SHGC
