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 Stevens Park in Burlington, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
Inland areas in this region experience some of the highest solar irradiance globally. Combined with the reflective properties of modern low-e glass, this creates ideal conditions for concentrated reflection damage.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
