Do you know what ‘selectivity’ means? Are you struggling to remember specific equations to calculate the acoustic performance of glass? Do you know what a Moiré pattern is? The Guardian Glass Technical Glossary provides definitions of these terms and many others.

The glossary is an alphabetical listing of glass-related terms and phrases with definitions of each, including graphical illustrations and diagrams where helpful. The glossary contains a wide variety of terms including acoustical information and calculation formulae; glass types; Colour Rendering Index; dry glazing; infrared energy; Low-E glass; Moiré Patterns; selectivity; shading coefficient; spacer; sputter coating; UV transmittance; U-value; visible light; wind and snow loads; and much more.
