Increase Window Security & Sound Reduction with Laminated Glass.
Threats
to retailers, facilities and homeowners in the form of vandalism,
burglaries and home invasions can be met head on with TUFF GLASS
laminated glass. TUFF GLASS is made up of two panes of glass, the
interior pane is two pieces of glass which are laminated to a tough
polyvinyl butyral interlayer that gives TUFF GLASS
its remarkable properties for keeping out intruders, added protection
against harmful UV rays and added noise reduction. The exterior pane can
be AFG Ti AC-36 Low E coating and an argon gas-filled airspace to
provide superb energy efficiency.
TUFF GLASS laminated film provides an invisible barrier that reinforces
your windows fragment retention by holding glass together during
accidental breakage, destructive weather, smash and grab crimes or acts
of terrorism. TUFF GLASS has a toughness that allows these films to
withstand day-to-day abuse and is recommended for residential, vacation
and commercial properties.
TUFF GLASS laminated film also provides help to seal out water, the
primary cause of property damage if the glass is broken during a storm
or vandalism.

SOUND TRANSMISSION LOSS OF WINDOW GLASS
When dual glazed units are used they typically work best to reduce
sound when the two lites of glass are different thickness and if one
pane is laminated.
SOUND REDUCTION WITH GLASS/AIR SPACE COMBINATIONS
Most window products today are dual glazed for increasing thermal
performance. The table below gives some examples of glass/air space
combinations and their Sound Transmission Class (STC) values. The STC
values are nominal values achieved by operable windows. The higher the
STC rating number the better the glass performs at sound reduction.
Actual STC values may vary slightly due to window size, type and
construction.
