LOW SOLAR HEAT GAIN COEFFICIENTS
SOLAR CONTROL
ENERGY PERFORMANCE
Low Emissivity (Low-E) glass is designed for optimal thermal performance, making it ideal for applications where temperature regulation is critical. By blocking UV rays and providing superior insulation, Low-E glass enhances energy efficiency. This is achieved through a specialized thin metallic or oxide coating that minimizes the transmission of short-wave solar energy while retaining long-wave heat generated indoors by heating and lighting systems.
Tunnel Tech offers 2 Low-E glass options:
Single Silver Low-E
Key Benefits:
- High visible light transmittance ensures adequate indoor natural daylighting.
- Energy effectiveness as high far infrared reflectance contributes to a low U-value, reducing thermal transfer and improving energy efficiency.
- Wide range of shading coefficients (SC) suitable for different geographical locations, allowing for flexibility in managing solar energy transmittance.
Features:
- Sufficient natural daylighting indoors.
- Solar energy transmittance; varying shading coefficients suitable for different geological locations.
- High Far Infrared Reflectance contributes to a low U-value that reduces thermal transfer from temperature differences and enhances energy efficiency.
Double Silver Low-E
Key Benefits:
- Two Silver Layers enhanced performance compared to single silver Low-E glass.
- Better Light Control: maintains high visible light transmittance while reducing the shading coefficient (SC).
- Cool Lighting Effect: Filters sunlight to create a cooler lighting environment, ideal for high-transparency architectural designs.
Features:
- High Visible Light Transmittance: Ensures better natural lighting.
- Low Solar Heat Transmittance: Effectively reduces solar heat radiation.
