Why This Matters
Low-e glass was a major step forward in window efficiency. But it has limits. Low-e retrofit film extends that performance further, adding a second emissivity layer that existing glass lacks.
Near Antech in San Jose, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
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
Most residential window film installations are completed in a single day. The film cures fully within 30 days, after which performance is at its rated specification.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
