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 ALDI in Champaign, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit 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.
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
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 ALDI in Downtown Champaign, Champaign experience low-e glass performance conditions that make window film particularly effective. Low-E Retrofit Window Film is specifically engineered to address this solar exposure.
