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 DeBary Hall Historic Site in Sanford, south- and west-facing windows receive the most direct solar load and benefit most from film. 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.
The marine layer that covers coastal areas in the morning burns off by midday, leaving afternoons with intense, direct sunlight. This pattern creates a predictable daily window for reflection damage — typically 1pm to 5pm.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
