Custom Build Decks |
 |
In architecture, a deck is a flat surface capable of supporting weight, similar
to a floor, but typically constructed outdoors, often elevated from the ground,
and usually connected to a building. The term is a generalization of decks as
found on ships.
Wood or timber "decking" can be used in a number of ways - as part of garden
landscaping, to extend living areas of houses, and as an alternative to stone
based features such as patios. Decks are made from treated lumber, composite
material, Aluminum, Western red cedar, teak, mahogany, ipê and other hardwoods
and recycled planks made from high-density polyethylene (HDPE), polystyrene (PS)
and PET plastic as well as mixed plastics and wood fiber (often called
"composite" lumber). Artificial decking products are often called "wood-plastic
composites".
Historically, the softwoods used for decking were logged from old growth
forests. These include Atlantic white cedar, redwood and Western red cedar (redcedar).
Atlantic City built the first coastal boardwalk in the United States, originally
constructed of Atlantic white cedar. However, it was not long before the
commercial logging of this tree and clearing of cedar swamps in New Jersey
caused a decline in the availability of decking. Atlantic City and New York City
both switched to Western red cedar. By the 1960s, Western red cedar from the US
was declining due to over-logging. More expensive Western red cedar was
available from western Canada (British Columbia) but by then, pressure treated
pine had become available.
 But
even with chemical treatments (such as chromated copper arsenate or CCA), pine
decking is not as durable as cedars in an outdoor environment. Thus, many
municipalities and homeowners are turning to hardwoods. Decks are often built
from pressure treated wood. Pressure treated wood is long lasting and holds up
to wet and icey weather conditions. pressure treated wood however is treated
with chemicals which have been known to be toxic. slivers received from pressure
treated wood most generally become infected. Pressure treated saw dust also
contains toxins such as strychnine, also often used as rat poison. These toxins,
when inhaled, can require hospitalization for both acute and chronic exposures.
Generally, hardwoods used for decking come from tropical forests. Much of the
logging taking place to produce these woods, especially teak, mahogany and ipê,
is occurring illegally, as outlined in numerous reports by environmental
organizations such as Greenpeace, Friends of the Earth and Rainforest Relief. US
tropical wood imports are rising, partly due to the demand for decking.
The deck of a house is generally a wooden platform built above the ground and
connected to the main building. It is generally enclosed by a railing for
safety. Access may be from the house through doors and from the ground via a
stairway. Residential decks can be constructed over steep areas or rough ground
that is otherwise unusable. Decks can also be covered by a canopy or pergola to
control sunlight.
Larger buildings may also have decks on the upper floors of the building which
may be open to the public as observation decks. A deck is also the surface used to construct a boardwalk over sand on barrier
islands. Laying deck or throwing deck refers to the act of placing and bolting down cold
formed steel beneath roofing and concrete floors. This is usually done by an
ironworker, sometimes in conjunction with a cement mason or carpenter. It
regarded as one of the most physically demanding jobs in the iron working
industry. In the UK the 2007 ban on smoking in public buildings was expected lead to an
increase in the use of timber decking for outdoor spaces where smokers can
gather.
