Solux-E®: year-round comfort and energy savings

Your glazing plays a crucial role in the way your home feels and functions so we've made finding the right glass as simple as it should be with the innovation of Solux-E®.

Solux-E® reduces the amount of heat that passes through the glass while still letting natural light through, improving the thermal efficiency of a home. It offers year-round comfort and a warmer, drier and healthier home.

Solux-E® is standard with The AGP System® and is the all-in-one option to help you get the most out of your glazing.

What is Solux-E®?

Solux-E® is a low emissivity (Low-E) coating on the glass, which is virtually invisible. It is incorporated into The AGP System®, improving the level of insulation in the home. Solux-E® is applied to the inside surface of the exterior glass pane, protecting it from the elements. Solux-E® coating reflects the heat back to the inside, reducing winter heat loss through the glass. The reverse happens during summer helping to limit overheating.


We developed this state-of-the-art product using the latest global technology, optimised for New Zealand conditions.

Blocking excessive heat
Close

Solux-E® lets the sun’s visible light pass through but reflects the ‘sun's heat’ back out by 34% better* than standard double-glazing. With less heat entering the home, there’s less need for air-conditioning to keep your home cool.

Controls fading
Close

Solux-E® helps protect furnishings in your home from fading by reducing the amount of damaging light that enters through the glass 19% better* than standard double glazing.


*Based on 4mm Solux-E / 16mm ATS / 4mm compared to 4mm / 16mm Air / 4mm.

Retaining heat
Close

Solux-E® reflects the warm air in the home back into your house rather than escaping through the glass. This reduces winter heat loss by 59%* when compared to standard double glazing.

The internal and external glass panes in The AGP System® are separated with ATS® to reduce the likelihood of condensation forming on the glass inside the home, reducing the risk of mould growth and increasing the homeowner’s health and wellbeing.

A more constant temperature means less energy used to heat and cool the home, providing energy savings year-round. Reduced energy consumption puts less demand on New Zealand’s power grid, reducing the environmental footprint.

Year round comfort

Solux-E® works hard to minimise heat flow allowing you to stay warmer through winter and cooler through summer. You'll have less warm air escaping in the winter and less heat entering through the glass in summer without the need to use tinted glass, also known as Solar Heat Gain Coefficient (SHGC).
