LoE-i89® soft coat low-e glass

A superior soft coat low e glass for residential windows – available single glazed or double glazed in an IGU

LoE-i89® is a soft coat low-e which represents is the next generation of low-e glass, outperforming the others all year round, especially during the colder months. The i89 technology reflects escaping heat back into the room and reduces U-Values to meet the strictest energy efficiency guidelines, even as a single glazed unit.

Because it is able to perform as a monolithic single glazed unit, it is the superior economical solution for residential windows. Better still, when combined with a high performance low-e hard coat like our LoĒ-366®, it achieves unprecedented performance such as a Solar Heat Gain Coefficient (SHGC) of 0.27 and a U-Value of just 1 . 1 – the lowest U-Value currently on the Australian market.

Unlike other low-e glass, it achieves optimum clarity, without the haze. It also comes standard with Neat® technology, an easy-clean coating which uses the sun’s rays to lift dirt so the rain can wash it away with minimal streaks.
