HeatShield Window Coating

HeatShield™ Window Coating



eTime Energy’s industry leading HeatShield™ transparent liquid window coating is an alternative to traditional window films.  The unique nanotechnology coating is engineered for durability, resulting in a long-lasting, smooth, transparent finish that is virtually invisible on your windows.  Save_energy_sunHeatShield™’s ability to block over 50% solar heat gain, reject over 90% UV rays  and still allow over 70% visible light makes it ideal for window retrofits in institutional, commercial and hospitality buildings where patrons’ comfort and energy efficiency are priorities.  Lower demand on your air conditioning system means you consume less peak energy, reduce your carbon footprint and save money on electricity.

HeatShield™ is suited for both warm and temperate climates.  When applied to windows, the coating blocks the exterior summer heat from entering and prevents indoor heating from escaping in the winter time.  Typical space cooling energy savings of 20% to 40% in temperate climates.
