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 Sellwood Riverfront Park 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.
Solar control film addresses both reflection and heat transmission. It's the right choice when you want to stop turf burn AND reduce interior heat gain. Slightly more visible from outside than anti-reflective film.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.
