What glazing finish is best for me?
Glass types with a higher percentage of solar heat reflection and lower light transmission will reduce solar gain – to avoid excessive heat from the sun passing through the glass.
U-Values describe how heat is transferred through a structure. Lower numbers indicate better insulation.
‘Standard’
Clear – U Value 1.2 – Solar Heat Reflection 31% – Light Transmission 77%
Neutral – U Value 1.2 – Solar Heat Reflection 59% – Light Transmission 44%
Blue – U Value 1.2 – Solar Heat Reflection 73% – Light Transmission 32%
‘Premium’
Clear – U Value 1.0 – Solar Heat Reflection 38% – Light Transmission 70%
Blue – U Value 1.0 – Solar Heat Reflection 83% – Light Transmission 23%
Aqua – U Value 1.0 – Solar Heat Reflection 82% – Light Transmission 28%
