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 RiverPlace Hotel 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.
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.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
Climate & Solar Performance
Properties near RiverPlace Hotel in Southeast Portland, Gresham experience low-e glass performance conditions that make window film particularly effective. Anti-Reflective Window Film is specifically engineered to address this solar exposure.
