Why This Matters
Low-e coatings on double-pane windows are optimized for winter heat retention. In summer, they still allow significant solar heat gain. Window film corrects this seasonal imbalance.
Near Sunflare Solar in Pomona, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
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
Low-e retrofit film is the most cost-effective upgrade for older single-pane windows. It adds a low-emissivity layer that dramatically improves thermal performance without full window replacement.
Perforated film solves the privacy-versus-light tradeoff for street-facing rooms. The micro-hole pattern maintains outward visibility from inside while blocking the view from outside during daylight hours.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
Climate & Solar Performance

Installation Guide
The best time to schedule installation is in the morning, before the glass heats up. Hot glass causes the slip solution to evaporate too quickly, making it harder to position the film correctly.
