Thermal Insulation Test: Rare-Earth Glass vs Standard Low-E
Glass performance has a big impact on indoor comfort and energy use. To compare standard Low-E glass with EASYTO’s rare-earth laminated glass, we ran a simple thermal insulation test under controlled conditions.
Test Setup
- Two identical, insulated one-cubic-foot chambers with digital thermometers.
- Infrared lamp to simulate solar radiation (same distance and duration).
- Left chamber: standard hollow Low-E glass. Right chamber: EASYTO rare-earth laminated glass.
- Exposure time: 10 minutes.
Results (After 10 Minutes)
- Standard Low-E Glass: 31.6 °C
- Rare-Earth Laminated Glass: 22.8 °C
Temperature difference: ~8.8 °C (≈ 9 °C) cooler with rare-earth glass under the same conditions.
What This Means
- Lower heat gain: The rare-earth chamber stayed close to room temperature, indicating better control of solar heat.
- Cooling effort: At a 20 °C comfort setpoint, the rare-earth result suggests substantially less cooling effort compared with the Low-E setup.
- Comfort & efficiency: Less heat entering the space can translate to improved comfort and reduced HVAC load.
Why Rare-Earth Glass Performs Differently
EASYTO’s rare-earth technology leverages LSPR (localized surface plasmon resonance) characteristics of rare-earth elements to selectively block infrared and UV portions of the solar spectrum while maintaining high visible light transmission.
Test Notes & Disclaimer: This is a bench demonstration using small insulated chambers and an IR lamp to simulate sunlight. Results reflect this setup and may differ in real buildings due to glazing type, frame, installation, climate, orientation, and HVAC controls. Performance claims should be validated with project-specific modeling, certifications, or independent testing where required.
