Parapet is a common sight in modern buildings. It is
gradually becoming a standard or a precedent for everyone contemplating
erecting a befitting structure. The most significant relevance of parapet is
that it protects the edge of roof assemblies from wind uplift forces. When wind blows against a building
it produces vortices at the roof edges that create huge pressure differences at
roof perimeters that pull off roofs from buildings.(vortices refers to mass of
air,etc that spins around very fast and pulls things into its centre). Parapets
reduce these pressures.
These days burglars are found of breaking in through the
roof down inside the building. But with parapet it is not possible to break in
through that part of the house. Additionally, parapet enhances the over all
beauty of the building. In fact, it catches the eyes and adds some aesthetic
value to the environment.
HIDDEN DANGER
It could pose a real danger for firefighters in cases of
fire outbreak. Because of intense fire heat, it could collapse from top,
thereby making it unsafe for firefighters to work under. On July 05, 2008, a 42
year old male volunteer fire chief was killed when he was struck by a
collapsing brick parapet wall during a commercial structure fire.
Although this is not a danger in itself, it is expensive to
build. For this reason, the average man need not consider the trend if he
operates on a lean budget. A friend once told me that it could be as high as
250,000 to make.
