Why This Matters
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 without window replacement.
Near Cinta Aveda Institute in Berkeley, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit 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.
The marine layer that covers coastal California in the morning burns off by midday, leaving afternoons with intense, direct sunlight. West-facing rooms without film are at their hottest between 2pm and 5pm.
The Solution
Perforated film solves the privacy-versus-light tradeoff. The micro-hole pattern maintains outward visibility from inside while blocking the view from outside during daylight hours.
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.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.
