Why This Matters
Seasonal changes affect the burn pattern. In summer, the sun is high and the reflection angle is steep — damage tends to appear closer to the window. In winter, the low sun angle creates a longer, more intense focal path.
Near Keith's Sporting Goods in Gresham, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
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
Ceramic window films are the premium solution. They use non-metallic ceramic particles to absorb solar energy before it can reflect and focus. No signal interference, no mirror-like appearance, and no compromise on clarity.
Perforated film is the most aggressive diffusion solution. The micro-hole pattern physically prevents any focused beam from forming. Best for large picture windows with severe reflection problems.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
