E-Tech Lite

Improve the energy efficiency of your
home while enjoying natural light and
reducing heat from the sun.


What is E-Tech Lite?

E-Tech Lite is an energy efficient glass offering
insulation with high visible light transmission,
ideally suited to Australian residential windows.

E-Tech Lite has been designed for the harsh
Australian climate to assist in achieving
energy star ratings for home designs,
while still capturing natural light and views.

Manufactured using a hardcoat low-e coating
for excellent durability and ease of processing
and handling.

Low e-glass has a coating that
allows natural light through without
emitting radiant heat, maximising
light and energy efficiency.

Over 87% of the heat in your home during summer comes from the windows.
