IGUs, or Insulated Glass Units, are
one of the most popular window forms. Laminate glass, as a safe and
thermally-effective alternative, is also a popular choice for window
installation. The two types of glass have key differences that you should
be aware of:
- IGU provides higher thermal
efficiency. Because of the double or triple layers of glass and
the air or gas-filled spacer, the insulation value is considerably higher.
- IGU offers clearer vision.
Even though they consist of multiple layers of glass, IGUs are usually
somewhat superior to laminate glass in the level of clarity that the
- Laminate glass is safer.
If you live in an area of high wind or hurricane risk, you may want
to consider laminate or protective glass, which is far more resistant
to breaking or shattering.
- Laminate glass provides
improved sound insulation rating and blocks harmful rays. Without
special glazing, IGUs do not provide the same level of sound insulation
that laminate glass can provide. In addition, laminate glass blocks
up to 99 percent of the sun’s UV rays.
