Low E Glass

What Low E means: It's short for "Low Emissivity" glass.
Energy efficient: Low E glass is very energy efficient with a special coating that lets in light while retaining heat inside to help maintain indoor comfort levels.
Reduce power bills: Metro Low E glass can reduce heat loss by up to 61% compared to standard double glazing which will help save you money on your power bills.
Helps reduce overheating risk: If overheating is an issue for your home in the hot summer months, choose from our three solar control glass options - Xtreme™ Low E, SunX™ Grey Low E or SunX™ Reflect, all help reduce solar heat by up to 71% when compared to standard double glazing. They also keep your home warmer in the colder winter months.
Lets in natural light: Visible Light Transmission also called "VLT" is a measure that tells you how much natural light is coming through the glass. Each of our Low E glass lets in different levels of light, from Xcel™ Low E that lets in 80% of visual light, to Xtreme™ Low E that lets in 74% visual light - both are perfect for creating naturally light filled spaces.
SunX™ Grey and SunX™ Reflect Low E are our highest solar control glass, letting in less visual light - great for hot, sunny locations and rooms that experience glare.
Crafted for New Zealand conditions: Our selection of Low E glass is tailored to suit New Zealand conditions, offering a variety of performance benefits to cater to your specific priorities.
