Thank you! You mentioned LowE will take care of radiant heat, does this mean tinting is more for direct heat? Does tint help with radiant heat? The glass is Tempered Guardian SN68 and it's spec does not specify hi-performance or LowE2/E3. When viewing white window shade, it does have a green tint to it but does not appear abnormally green so I think it's just standard LowE? The specs are below: I think HVAC is definitely 1 of 3 big factors in our heat but I don't think it is just duct size. We have a 18,000btu ducted split unit for just upstairs (~450sqft), running 10" ducts but I think with all the heat coming up from downstairs, it is just not enough. So I'm trying to gauge to see if tint will make a big difference or if I should just invest in tearing out and upsizing HVAC (this is more work than preferred as it is a modern design with no attic or dropped ceilings).

About 2yrs old. Should be standard low-e

I've been looking at tinting my second floor windows/sliding doors (9 floor to ceiling low-e dual pane glass totaling ~400sqft) to combat heat and reduce a little glare. The space is an open loft concept so the stairs lead directly to the space. And from the first floor, leading up to the stairs is a very long hallway that I've discovered to act like a wind tunnel so I think a good portion of the heat is coming from the first floor raising up. The glass panels are situated as such: 6 of these panels are south facing with overhangs about 1/2 the glass' height. 2 panels are east facing without overhang 1 panel is west facing without overhang. I've been considering Vista's VS50 or Solar Gard's Hilite 55/70 (space is used as my wife's office and she is against going below 50% tint and anything reflective) but beginning to wonder with the overhang, will I benefit much from tint as the majority of the glass is in indirect sun? During the summer heat, I'm seeing direct sunlight through the glass as such: 2 east panels get direct full sun during the morning 6 south panels get no direct sun as it is covered by the overhang. 1-2 panel start to get partial direct sun starting mid afternoon 1 west panel gets direct full sun starting mid afternoon With the HVAC running, we're seeing about 80-85 degree temperatures inside. Trying to gauge if I'll see any improvements and if there'll be any ROI from tinting.
