Double Glazed Unit

Your Spacer Bar
Thermal Spacer
A thermal spacer provides low thermal conductivity. This means heat inside will take longer to transfer outside. By reducing the heat transfer at the edge of the glass a thermal spacer minimises the risk of condensation on the interior glass surface, and improves thermal comfort for all building occupants.
Considerations
Glazing compounds, sealants and gaskets need to be approved by Viridian for suitability.
Frame design – the Viridian Warranty relies on frame design in accordance with AS/NZS4666. Do not expose edges to standing water and moisture as this can result in seal failure. The frames must incorporate impervious weather seals or a self draining system.
Wind load and safety determine the type and thickness of glass required – refer Australian Standard AS1288 or New Zealand Standard NZS4223.
Installation must be in accordance with AS/NZS4666.
Visual characteristics and manufacturing tolerances – LightBridge1.1™ is manufactured to AS/NZS4666.

Where double glazing units have been used, LightBridge1.1™ Low-E coatings are on surface 3 and 5. Centre-of-glass U-Values were calculated by Calumen II software based on EN673 conditions. SC, VLT and Tdw-ISO values were calculated by Window 7 software based on NRFC 100-2010 conditions.
