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 Willamette Park in Gresham, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. 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.
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.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.

Installation Guide
The best time to schedule installation is in the morning, before the glass heats up. Hot glass causes the slip solution to evaporate too quickly, making it harder to position the film correctly.
