Home Window Film Energy Savings Calculator

Estimate How Residential Window Film Could Improve Your Home’s Energy Performance

LLumar residential window film is applied to existing glass to help manage solar heat, reduce glare, filter harmful UV rays, and improve comfort without replacing your windows. For homeowners in Sanford and surrounding Central Florida communities, that can be especially useful in rooms with strong afternoon sun, large glass areas, or windows that contribute to uneven indoor temperatures.



The calculator lets you enter details such as your location, glass type, film selection, and home size to generate an estimated energy-savings result based on your project conditions.
