Why This Matters
Single-pane windows — still common in California homes built before 1980 — have almost no thermal resistance. Low-e retrofit film can cut their solar heat gain by 40–60% at a fraction of the cost of replacement.
Near Cole Hardware in San Francisco, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
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
The installation process is non-invasive: clean the glass, apply the film with a slip solution, squeegee out air pockets, and trim to fit. No construction, no permits, no disruption.
Hybrid films combine ceramic particles with metallic layers for maximum heat rejection. They're the right choice for extreme solar exposures or homes with very large west-facing glass areas.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
