Features & Benefits
- Exceptional performance in reducing summer heat gain and winter heat loss;
- High visible light transmission with low SHGC (for solar control);
- Safety toughened glass as standard with additional UV blocking and noise reduction options.
Applications
Residential and commercial glazing to meet any of either energy, noise, safety and security requirements.
Range

Design & Glazing Notes
Neutral 70 & 50 low-E coated glass is by default positioned on surface #2 of the IGU (coating facing inside of the cavity). When compared to ordinary single glazing, IGU’s can introduce some added complexities in relation to selection of glass types, manufacture and installation. IGU’s can also present issues relating to acceptable visual faults. For more information (Download)
