Why This Matters
Window orientation matters enormously. South-facing windows cause the most damage in winter when the sun is low. West-facing windows are the worst offenders in summer afternoons. The reflection angle changes with the season — which is why burn patterns can shift over time.
Near Energy Time Solar in Los Angeles, 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.
High solar intensity, clear skies, and widespread adoption of energy-efficient building codes make this region one of the highest-risk markets for window-reflection turf burn.
The Solution
After installation, the film is essentially invisible from inside the home. Exterior appearance changes slightly — the glass may look slightly darker or have a subtle tint — but the view and light transmission remain largely unchanged.
Low-e retrofit film is specifically designed to address the low-e glass reflection problem. It modifies the reflective properties of existing glass without replacement — the most cost-effective solution for new construction.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.
