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 Cougar Mountain Regional Wildland Park in Kirkland, 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 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.
