Low-E vs EnergyTech: what is the difference?
Both are the same kind of glass: a hard-coat (pyrolytic) Low-E coating, and they perform almost the same. EnergyTech is the Viridian brand, made in Australia, with certified performance data that energy ratings and building reports can quote. Low-E is imported unbranded Low-E glass: same job, lower price. Need certified data for your builder or energy assessor? Choose EnergyTech. Otherwise Low-E gives the same result for less.Prices: our online price for one 1000 × 1000mm double glazed unit (6mm toughened + argon + 6mm toughened), delivery included. The calculator gives the price for your size. Performance: supplier data for 6mm toughened / argon / 6mm units. Whole-window figures depend on the frame.
24mm double glazed unit, made to your measurements. The wider cavity or thicker panes give better thermal and acoustic performance than a 20mm unit.
Choose 24mm where comfort or noise matters most: bedrooms facing a road, west-facing living areas, or any room you are actively trying to make quieter and more stable in temperature. It needs a deeper frame rebate than a 20mm unit, so check your frame will take it before ordering.
Sealed at manufacture — cannot be cut, drilled or altered afterwards. Confirm sight size and rebate depth with your glazier or window supplier before you order.
Fogging between the panes on an existing unit means a failed seal; the unit needs replacing rather than repairing.

HOW YOUR GLASS IS HANDLED
- All glass meets Australian Standards.
Please check your glass before signing. If anything has been damaged in transit, tell the driver at the point of delivery and we will arrange a remake.
ON DELIVERY DAY
Someone needs to be on site to receive and check the order. Larger and thicker panels can be heavy enough to need two people to move safely. If you are unsure about the weight of your panel, ask us before delivery day.
