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
- Duo Ultra™ units are a higher energy performing product combining new generation ‘sputter coat’ low-E glass and is available as two glass coating types, Neutral 70 & Neutral 50;
- Neutral 70 coated glass offers high visible light transmission of 70% with low SHGC (solar control) of 0.35 whilst Neutral 50 offers moderate visible light transmission of 50% with a very low SHGC of 0.25. Option of Grey and other colour tones also available.

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)
