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 Dr. Michael Frommlet, MD in Gresham, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
High solar intensity, clear skies, and widespread adoption of energy-efficient building codes make this region one of the highest-risk markets for window-reflection turf burn.
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.
Perforated film is the most aggressive diffusion solution. The micro-hole pattern physically prevents any focused beam from forming. Best for large picture windows with severe reflection problems.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
Climate & Solar Performance
Properties near Dr. Michael Frommlet, MD in Downtown, Gresham experience afternoon heat gain conditions that make window film particularly effective. Low-E Retrofit Window Film is specifically engineered to address this solar exposure.
