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 Morrison Bridge in Gresham, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
The marine layer that covers coastal areas in the morning burns off by midday, leaving afternoons with intense, direct sunlight. This pattern creates a predictable daily window for reflection damage — typically 1pm to 5pm.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
