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, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
Inland areas in this region experience some of the highest solar irradiance globally. Combined with the reflective properties of modern low-e glass, this creates ideal conditions for concentrated reflection damage.
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.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.
