Why This Matters
West-facing windows receive the lowest sun angle in the afternoon — the same angle that drives the highest solar intensity per square foot of glass. This is why west-facing rooms overheat first.
Near Sunrun in Palmdale, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for luxury residence installations, which high-end homes require premium ceramic or spectrally selective films that preserve view clarity.
California's Title 24 energy code sets minimum window performance standards for new construction. Window film can bring older homes up to — and beyond — those standards at a fraction of the cost of window replacement.
The Solution
Quality window films carry 10–15 year manufacturer warranties. That's longer than most window treatments and comparable to the lifespan of the windows themselves.
Ceramic film is the premium option: non-metallic, signal-transparent, and highly effective at blocking solar energy. It costs 20–40% more than standard films but offers superior clarity and a longer lifespan.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
