The new retrofit option gives standard glass the performance of low emissivity windows, at a cost savings of up to 80% over replacement low e windows.

Solar Gard Silver AG 50 Low E window film transforms standard glass into high performance windows, reducing energy consumption year-round, lowering costs associated with heating and cooling, and improving a building’s carbon footprint.

During colder periods, the low e window film reflects 63% of interior heat back into a room, while only 16% of interior heat is reflected back into a room with untreated windows, the company said.

During warmer periods, Silver AG 50 reflects solar heat away from windows, keeping interiors cooler and reducing the need for air conditioning.
