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 Leach Botanical Garden in Gresham, year-round solar exposure can make solar control film a practical comfort and efficiency upgrade. 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
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.
