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 Keith's Sporting Goods in Gresham, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for multi-family residence installations, which condos and apartment buildings benefit from film to reduce hvac load and improve tenant comfort.
Periods of exceptionally clear, dry air in this region amplify solar intensity. During these events, window reflection can be 20–30% more intense than on a typical sunny day.
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.
Ceramic film is the premium option: non-metallic, signal-transparent, and highly effective at blocking solar energy. It costs 20–40% more than standard films but offers superior clarity and a longer lifespan.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.
Climate & Solar Performance
