Why This Matters
Glass is a poor thermal barrier. Even double-pane windows transmit significant solar heat — especially on south- and west-facing exposures where the sun angle is most direct.
Near Dr. Steven A. Dowshen, MD in Elsmere, california's 260+ sunny days per year make solar control film a year-round performance upgrade. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
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
Professional installation ensures the film is applied without bubbles, gaps, or edge lifting — all of which reduce effectiveness and shorten lifespan.
Low-e retrofit film is specifically designed for older single-pane windows. It adds a low-emissivity layer that dramatically improves thermal performance — the most cost-effective upgrade for pre-1980 California homes.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
