DefenseLite Energy (DLE) is a clear, retrofit energy shield and advanced low-E energy saving glazing system that installs over existing window glass and frames to provide multilayer protection against solar heat gain, air infiltration, UV rays, and heat transfer by creating a new insulating air space.
Utilizing high optic UV coated energy shields with built in infrared (IR) resistance and low-E film coatings, DLE can improve existing single-pane glass to perform as a new, high-performance triple-pane window system.
Interior mounted, and easy to service, DefenseLite Energy is a custom engineered building envelope solution that combines the best in materials science with a light weight retrofit solution for windows, providing advanced solar protection, insulation and sound control year-round.
DLE will triple the existing thermal transmittance (U values) and Solar Heat Gain resistance. Our smart energy-saving glass system can eliminate any air infiltration through your existing window.
Expect over 30% energy savings in cold climates, allowing for significant reductions in HVAC replacement which will more than offset the cost of the energy-efficient window improvements.
DLE also reduces street noise by up to 40% as an added tenant benefit.
DefenseLite Energy mounts in front of the existing glass and window frame on the interior of your structure, creating a perfect, retrofit energy-efficient glass system.
The extrusion creates insulating airspace and thermal buffer to your primary window, eliminating air infiltration while also improving solar heat gain. Our energy-saving glass window system can be easily removed for future window access.
