Low-E Glass
Features:
- Natural Color: Close to the original color of glass, providing excellent natural lighting and reducing the need for indoor illumination.
- High Transmittance, Low Reflectance: High visible light transmittance without causing severe glare pollution.
- Excellent Thermal Insulation: Extremely high reflectivity to infrared rays (heat sources), achieving a "warm in winter, cool in summer" effect.
Product Types:
- Single Silver Low-E Glass (SLE)
- Double Silver Low-E Glass (DLE)
- Solar Control Single Silver Low-E Glass (LES)
- Titanium-based Low-E Glass (TLE)
Notes on Use, Design, and Installation
Maintenance:
- Do not apply window tint/solar film, as it will cause thermal stress concentration leading to glass breakage (thermal breakage).
- Usage at altitudes above 1000 meters requires special discussion for pressure equalization.
Installation:
- Must be fabricated into "Insulating Glass Unit (IGU)": The coating layer is prone to deterioration when exposed to the atmosphere and cannot be used monolithically.
- Position of the Coating Surface:
- Subtropical/Tropical (Taiwan): Installed on the #2 surface (the second surface counting from the outside in) for optimal heat insulation.
- Cold Regions: Installed on the #3 surface for optimal heat retention.
- Identification Method: Test with a lighter; a normal flame is yellow, while the flame reflected by the Low-E coating will appear pink or blue.
- Drainage System: Metal window frames must have a good drainage design to prevent standing water from causing the glass to deteriorate and fog.
