What is it?
Spandrel glass is normally an opaque panel located between areas of
vision glass. They are used to conceal building components such as
columns, floor slabs, HVAC systems, wiring or plumbing.
Designs where large areas of glass are installed, such as curtain
walling and structural systems, often include spandrel panels.
Depending on the design the spandrel color may be selected to match
the vision glazing providing a "look-a-like" system where the
spandrel and vision glazing look similar when viewed from outside
the building. Alternatively the spandrel may be colored to provide
contrast. Spandrel glass must always be toughened or heat
strengthened to avoid thermal stress breakage.
Matching spandrel glass to vision glass with a high light
transmission or low reflection can be difficult. The degree of
color and visual similarity can vary greatly depending on a number
of factors including: light transmission, time of day, weather
conditions and interior lighting and shading.
In general, glass with high light transmission is most suited to
contrasting spandrel panels, whereas glass with a low light
transmission and higher light reflection are more easily matched to
the spandrel panels. We always recommend that you view a full size
outdoor mock-up for assessment of the visual appearance and
approval of vision and spandrel glass.
Spandrel glass can be glazed singly or as a part of an Insulating
Glass Unit to provide the shadow effect of adjacent vision units.
Spandrel glass can be insulated with a variety of materials to meet
even the most exacting of standards.
