greenhouse - n. a building with
roof and walls of glass,
often heated, and used for
growing flowers and plants
that need warmth, or for
forcing early produce
- The New Lexicon Webster’s
Dictionary of the English Language,
Encyclopedic Edition, 1989. |
The
traditional definition of a
greenhouse is much too simple to
apply to today’s greenhouses. The
roll of greenhouses within the
agricultural, commercial and
residential building industry has
changed drastically during the past
several decades. In the last few
years the glass itself has to a
great extent been substituted by a
new high grade material
-
polycarbonate.
Polycarbonate is a hard
plastic glazing material
which approaches glass in
its clarity and light
properties, with
transmission values of up to
92%. Advantages
of polycarbonate include:
-
Insulating effect of
thermo windows, creating
an even growing habitat
and extending the
growing season
-
Virtually unbreakable
-
Sheets are light and can
be supplied in the exact
length needed
-
New polycarbonate panels
deliver light
transmission even higher
than single glass
-
Available with
anti-condensate coating
on inside surface to
reduce condensate
dripping
-
Available with UV
protected outer surface
to provide long life
under high sun
conditions
-
10 year life span
guaranteed by most
manufacturers
Semi-rigid sheets polycarbonate
sheets are available in several
standard sizes and configurations.
The two primary configurations are
single layer and multi-layer sheets.
The layer configurations refer to
the number of walls separated by
layers of air.
Greenhouse
applications generally see single
layer (no air layer), double layer
(two walls separated by air), or
triple layer (three walls and two
air separations).
Architectural
applications have a variety of other
configurations available. The air
between the sheet layers helps
reduce heat loss, but as the number
of sheet layers increases the amount
of light transmitted through the
panels decreases. The designer must
therefore decide which is more
important -- light transmission or
insulation.
