COPPER IN ARCHITECTURE
history
Copper has been used as a roofing material for
centuries. In America, the use of copper in architecture has been
steadily growing since the time Paul Revere founded his copper
company. One of the oldest copper roofs in America is Christ Church
in Philadelphia, built in 1787.style
Copper has traditionally been favored by architects due
to its endurance and lasting beauty. Today copper can be found in
all types of architectural applications including industrial,
contemporary and historical styles. Copper on a building enhances
the features, adds substance to the architecture and value to the
building.
appearance
Copper is best known for its patinated green color.
After installation, copper will turn from its shiny salmon color
through various shades of bronze and hues of green before reaching
its final patina, the familiar green color. This process can take
25-30 years.
maintenance/endurance
Though copper has a higher cost initially, properly installed copper
roofing and flashings can last a lifetime with little or no
maintenance. Copper is not only durable but naturally resistant to
fire, as well as, corrosion and oxidation from severe weather or
industrial conditions.
materials/planning
The use of copper in architecture is a complicated process. Copper
is available in red or plain, light green pre-patinated and pewterie
gray alloy coated as well as many different weights and tempers. The
copper product selected for a particular application must take into
careful consideration the structural requirements, location, and
conditions of the building.
execution
Proper planning precedes fabrication and installation. At C.G.
Bostwick, we have a well-equipped sheet metal shop where we can
custom manufacture or reproduce even the most elaborate metal
fabrications. Many buildings require custom-made
gutters/downspouts, and accessories that we make in our shop and
install on site. environmental and cost performance objectives
Building a sustainable world should include copper for its
contribution to environmental performance. Copper is one of the most
easily recycled metals available. Nearly all the copper ever mined
is still in use today. Copper is totally recyclable. Each year the
amount of copper recycled in the United States is equal to the
amount taken from newly mined ore. Copper is an abundant natural
resource. Only 12% of the worldwide resource of copper has been
mined throughout history.
"Longevity, lasting a century or more copper roofs do not need to
be replaced. This longevity reduces the need for new roofing
materials and prevents the waste generated from other old worn
roofing material. Across its life cycle - from extraction to
recycling - copper has a minimal impact on energy consumption and
natural resources, while its use has an immensely positive impact on
energy efficiency, indoor air quality and life cycle costs."
