LLumar window film provides an effective way to save energy and resources by reducing solar heat gain and glare through windows. The film cuts excessive heat and glare, enabling rental of rooms with windows and paying for itself quickly. It reduces solar heat gain by up to 84% and improves insulating properties by 30%, delivering average payback of just 2.65 years. LLumar lowers energy costs by 5-15% and helps meet sustainability goals like LEED guidelines by lowering CO2 emissions from reduced energy usage.
