Why This Matters
Modern energy-efficient windows use a low-emissivity (low-e) coating that reflects solar energy. When the glass is slightly concave — common in double-pane units — it focuses that reflected energy into a concentrated hot spot.
Near Gresham DEQ Test Station in Gresham, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for luxury residence installations, which high-end homes require premium ceramic or spectrally selective films that preserve view clarity.
This climate — 260+ sunny days per year in most areas — means the reflection problem isn't seasonal. It's year-round, with peak intensity in summer and a secondary spike in winter when the sun angle is low.
The Solution
Low-e retrofit films are the most targeted solution for the most common cause. They add a secondary low-emissivity layer to existing glass that changes the reflection angle and reduces the reflective intensity below the damage threshold.
Anti-reflective film is the most targeted solution for turf burn: it scatters the focused beam without significantly changing the window's appearance or reducing interior light. Best for situations where the reflection path is the primary problem.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
