Why This Matters
Low-e coatings are applied to the inner surface of the outer pane in double-pane windows. This placement maximizes their thermal efficiency — and also maximizes their reflective focus on anything in the sun's path.
Near Gresham DEQ Test Station in Gresham, south- and west-facing windows receive the most direct solar load and benefit most from film. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
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
Window film works by either absorbing the solar energy (ceramic and solar control films) or scattering it (anti-reflective and perforated films) so it can't concentrate into a hot spot.
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.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
