Why This Matters
Low-e glass reflects up to 70% of solar energy. When that reflected beam hits artificial turf at the right angle — typically in the afternoon when the sun is lower — surface temperatures can exceed 200°F within minutes.
Near Kaiser Permanente Hilo Clinic in Hilo, south- and west-facing windows receive the most direct solar load and benefit most from 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
DIY film application is possible for smaller windows, but professional installation is strongly recommended for large picture windows or any window where the reflection path is severe. Improper application leaves bubbles and gaps that reduce effectiveness.
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.
