What Low-E Window Film Is & How It Works
Low-emissivity (Low-E) window film carries a microscopically thin coating that reflects infrared heat. The result is improved year-round energy efficiency — keeping unwanted heat out and conditioned air in.
How It Differs From Standard Solar Control Film
Standard solar film primarily blocks incoming heat. Low-E film works in both directions: it keeps heat out in summer and helps retain interior heat in winter, improving comfort across seasons.
Why Low-E Makes Sense in LA
In Los Angeles the main benefit is heat rejection, but Low-E film is also valuable for coastal homes and older houses where winter heat retention and draft reduction matter.
Best Applications
Low-E film is ideal for homes with significant glass:
- Homes with large glass areas
- Open-plan living rooms
- Older homes without double-pane glass
Low-E Film vs Low-E Glass Replacement
Compared to replacing windows with Low-E glass, Low-E film delivers much of the performance at a fraction of the cost — with no demolition and minimal disruption.
Energy Savings
Typical projects see a 15-30% reduction in heating and cooling costs. We install Low-E products from LLumar and 3M.
Pricing
Pricing runs $10-$18 per square foot depending on film and window type.
