Pretty good presentation, but LowE coatings are applied to surface 2 (most often) or 3 (less often), glass surfaces inside the IG unit, not on the exterior of the glass panes.

Sunrise window rating that I received from window company yesterday is 0.02 however your video mentions that they have 0.05. How can I get the accurate AI rating ?

The AI of any window is going to be dependent on the window type, the size of the window, whether they include grids, etc. It does make for a bit of a moving target -- the Sunrise slider for instance is nearly always going to have a worse AI than the fixed frame model. Typically, the published AI is for the double hung in a standard size with grids. That's what we try to use -- but it will vary based on the window specifics. Sunrise makes a very good window though...
