Why This Matters
The reflective coating on low-e glass is invisible to the naked eye. Most homeowners don't know their windows have it — which is why the burn pattern seems mysterious until someone explains the optics.
Near Rooster Rock State Park in Gresham, south- and west-facing windows receive the most direct solar load and benefit most from 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
Solar control films work on the absorption principle: they capture solar energy in the film itself, converting it to heat that dissipates into the glass rather than reflecting outward. Effective, durable, and widely available.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
