INSULATING GLASS UNITS
KEEP YOUR COOLER IN SUMMER,
WARMER IN WINTER AND REDUCE SOUND TRANSFER THROUGH YOUR
WINDOW
insulating glass units, sometimes
called "double glazing", are manufactured by permanently
bonding two panes of glass together with an edge spacer,
sealing in a volume of dry air and creating a highly
efficient
insulator. They significantly further advantages of reducing
the transfer of noise through windows, reducing the formation
of condensation on the inside of windows, and slow the fading
of materials by reducing the penetration of the ultra-violet
rays in sunlight. Units can be manufactured with normal
cleat or tinted glass, with "low e" low heat transfer
glass, with toughened or laminated glass. Various combinations
can offer very high security and/or saound reduction advantages
as well as the thermal improvement characteristics. Units
can be fitted to existing windows in home by using a special
adaptor system. Typical performance data for some common
units are shown at the left.
