low e 180 vs low e II
Just hoping for some input on using low e 180 windows for our whole house - located in south-eastern Ontario, four seasons, lake location, (any other info needed?).
Have been given a great quote for a good quality vinyl with low e 180 argon, but wondering if we are missing out by not using the low e II (i.e. Marvin Integrity) for our region? Or a combo?
I see that the 180 has been recommended for south facing windows, but wonder if there is a significant downfall for use on other sides of the house.
