Thermal Insulating Window Coating
(Plus Air Freshening System)
All Season Energy Savings
Cuts Heat Loss through Windows in Winter - Less Energy to Heat
Cuts Heat Gain through Windows in Summer- Less Energy to Cool
Warm in Winter
- Keeps warm in winter by selectively transmitting most of the visible
light with its warmth
- At the same time, Hot Guard™ reduces infrared heat from escaping through the window
- The result - a warmer, cozier room in winter
Cool in Summer
- Lets in visible light
- Significantly cuts incoming infrared solar heat that accounts for 43% of inbound solar energy
- The result - a cooler, more energy-efficient room in summer
Controls Condensation on Windows - Less heat escaping in winter also means less condensation on the outside of your windows.
Reduce Indoor Air Temperature by 5-15°F in Summer
Reduce Air Conditioning Costs by 10-20%+
Reduce those cold spots near the window
Fight Global Warming by Keeping Cool
Reduce Greenhouse Gases by Making your Home more Energy Efficient

How Hot Guard™ Plus Works
Hot Guard™ Plus uses nano-sized metallic oxides to selectively block portions of the light spectrum while letting other portions through.
- Most visible light shines through. About 70%
- Much of the heat-carrying, infrared part of the spectrum is reflected or absorbed by the metallic particles.
Hot Guard™ Plus also used nano-sized oxides as photocatalysts to capture energy from the sun and even household lighting to breakdown the causes of odor in the home. Because these are passive catalysts, they are safe to use and gentle on the environment. Originally developed to counter sick school syndrome, this is one of the most effective photocatalysts in use today.
