Brad is installing windows on the storefront of a bank in an area known to be at risk of fires in the dry season. Which of the following is least likely to be true of the windows he is installing?

A.
The glass has embedded wires.

B.
They are made of glass-clad polycarbonate.

C.
The window material is acrylic glass.

D.
A solar window film has been added to them.

Explanation:
C: It is not likely that the windows Brad is installing are made of acrylic glass. Acrylic glass is made out of polycarbonate acrylic, and while it’s stronger than
standard glass, it is also combustible. When it burns, acrylic glass forms carbon dioxide, water, carbon monoxide, and compounds such as formaldehyde. Because
of its toxicity, it is likely that the fire codes for the bank’s location prohibit the use of acrylic glass. However, acrylic glass does have its uses. It is preferred as an
alternative to glass in some cases because it is easy to handle and process, and comes at a low cost. You can find acrylic glass at your local aquarium or pet
shop. It is often used to build residential and commercial aquariums. It is also used for aircraft windows, motorcycle helmet visors, and as spectator protection
around ice hockey rinks.
A is incorrect because embedded wires is a safety feature that is intended to reduce the likelihood of the window being broken or shattering. Windows with
embedded wires consist of two sheets of glass with the wiring in between. It is unlikely that the bank’s storefront windows have embedded wires. These windows
are not typically used in storefronts for aesthetic reasons. However, of the answer options available, this is not the least likely characteristic.
B is incorrect because it is very likely that the windows Brad is installing are made of glass-clad polycarbonate. Glass-clad polycarbonate is the strongest
window material available and is resistant to fire, making it a good choice for a bank at risk of going up in flames during the dry season. Be careful not to confuse
glass-clad polycarbonate with polycarbonate acrylic, which not only burns but produces toxic fumes while it does so.
D is incorrect because it is likely that a solar window film has been added to the bank’s storefront windows. A lot of window types have a film on them that
provides efficiency in heating and cooling. They filter out UV rays and are usually tinted, which can make it harder for the bad guy to peep in and monitor internal
activities. Some window types have a different kind of film applied that makes it more difficult to break them, whether by explosive, storm, or intruder.
