    Bird-friendly glass with clear views

VT: visible light let through. SHGC: share of solar heat let in. U‑factor: rate of heat loss; lower insulates better.

VT, SHGC and U‑factor are center-of-glass values for a 2-pane unit: 3 mm clear glass, 1/2 in (13 mm) airspace, 90% argon, coating on surface 2 (surface 3 for LoĒ-180 and LoĒ-180ESC; surfaces 3 and 4 for LoĒ-Di89; LoĒ-i89 on surface 4 with LoĒ³-366 on surface 2). U‑factor in Btu/h·ft²·°F. Calculated with LBNL Window 7 to NFRC 100 conditions. Actual values may vary due to production tolerances.
