DefenseLite™ Energy

DefenseLite Energy (DLE) is an energy-saving retrofit glazing solution composed of glass or UV coated polycarbonate energy shields for commercial buildings. DLE installations are custom engineered to conform with existing conditions and can be made utilizing low-E film coatings and infrared light (IR) resistant materials. This clear energy shield, also commonly known as a ‘window insert, or storm window,’ mounts over the existing glass and window frames.

Once installed, the system provides multilayer protection from air infiltration, solar heat gain, heat transfer, and UV rays by forming insulating air spaces.

The patented design of DefenseLite Energy blends the finest materials with a simple retrofit solution, leaving property owners with superior UV ray protection and remarkable energy efficiency without the significant costs of full window replacement. 

Energy-saving DefenseLite Energy retrofits can triple the current resistance to solar heat gain and thermal transmittance (U values) for existing glazing. It can also remove all air infiltration passing through your current window system and reduces street noise by 40%.

DefenseLite Energy mounts over the interior of existing glass and window frames. Installation of this retrofit glazing system can provide more than 30% energy savings in cooler climates, and significantly reduce HVAC replacement needs while improving U-values of existing glazing.

Measurable Energy Savings: DefenseLite™ Energy

Not to be confused with solar window film retrofits, DefenseLite Energy panels are advanced, Low-E energy-saving ‘overglaze alternatives that can enhance existing windows and doors without the need to replace existing glazing. With the installation of these retrofit energy panels, building owners can expect triple-pane window system performance. A DLE installation will even help with compliance to local carbon reduction mandates like New York City’s Local Law 97. 

Additional benefits include: 

  • Minimizes hot and cold zones in buildings
  • Regulates temperatures in all occupied spaces 
  • Low weight and cost-effective with high performance
  • Improves passive solar gain while controlling air infiltration
  • Installs quickly during off-hours
  • No need for construction permits
  • Easily removable for cleaning
  • Patented venting for climate and moisture control.
