I am probably buying Milgard windows and now am trying to decide if I want the SunCoatMax (SCM) glaze or not. SCM blocks 95% of UV rays and generally has a VLT of 65%. I've read plants don't need UV, they need light from other parts of the spectrum so the Low-e glass may have no or little noticeable effect.
Does anyone have experience with this? Particularly SCM?
I also rely on the sun to heat my home in the winter, but the SCM makes it sound like the product keeps the home warm in winter too - the best of both worlds - but logically this doesn't make sense to me. If it blocks solar heat in the summer it's going to block solar heat in the winter. Any thoughts?
