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 Smith Tower in Seattle, 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.
The California climate — 260+ sunny days per year in most regions — means solar heat gain is a persistent challenge. Window film addresses it at the source, without blocking your view.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
