SolarGard Ecolux is a low‑emissivity (low‑e) window film with an emissivity of 0.09. In practical terms, that means 91% of your radiant heat is reflected back into the room instead of being absorbed by cold glass and lost outdoors.
When you think you need to turn the thermostat up, it’s often not because the air is cold. It’s because your body is losing radiant heat to the colder glass surface nearby. Your body constantly emits radiant heat, and untreated glass happily soaks it up and leaks it outside. That “cold draught” sensation is really your own heat being pulled away from you.
Ecolux reflects your radiant heat back into the room before it reaches the glass. Instead of losing warmth to the outdoors, you retain more of the heat you’ve already paid for.
A simple test makes this obvious. Put your face close to Ecolux‑treated glass and you’ll feel your own body heat returning back to you. That’s the low‑e coating on the outer surface doing its job.
Ecolux doesn’t just make you feel warmer it measurably improves insulation performance.
Single glazing treated with Ecolux performs much closer to standard modern double glazing.
Older double glazing treated with Ecolux moves toward the performance of modern, energy‑efficient double glazing.
In other words, Ecolux upgrades the thermal performance of the glass you already have, helping you achieve modern‑level insulation without replacing your windows.
SolarGard Ecolux Low-E Heritage
As homes became better insulated everywhere except at the windows, it became clear that glass remained the major weak point in retaining heat.
Drawing on decades of Solar Gard’s glazing expertise, EcoLux was developed to provide a genuinely effective insulation upgrade without replacing existing windows. This premium low‑e film reflects 91% of radiant heat back into the room, helping older single and double glazing reach a far higher thermal standard while keeping the glass looking exactly as it should.
EcoLux is Solargard’s premium low‑emissivity (low‑e) insulation film. It reflects 91% of radiant heat back into the room, reducing heat loss through glass and improving comfort all year round.
When you sit near untreated glass, your body loses radiant heat to the cold window surface. Ecolux reflects that radiant heat back into the room before it reaches the glass, so you stay warmer without turning up the thermostat.
Yes. Ecolux significantly improves insulation performance:
Single glazing treated with Ecolux performs much closer to standard modern double glazing.
Older double glazing treated with Ecolux moves toward the performance of modern, energy‑efficient double glazing. It’s a powerful upgrade without replacing your windows.
Yes. A simple test proves it:
Place your face close to Ecolux‑treated glass and you’ll feel your own radiant heat gently returning to you. That’s the low‑e coating in action.
Ecolux can reduce the feeling of cold surfaces, which may even increase condensation. Condensation is influenced by ventilation, humidity, and lifestyle factors, so ideally these should be resolved with dehumidifiers.
Yes it will improve the insulation comfort further but will be less significant than on single or older double glazing
