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 Grossnickle Douglas R MD 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 trend toward drought-resistant and low-maintenance landscaping has driven massive adoption of artificial turf. The same environmental awareness that drives low-e window adoption also drives turf installation — creating a collision of two green technologies.
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
