FOUNDATION
The
foundation is prepared based on the soil type, its weight, amount of internal
friction, amount of holding and permissible ground pressure, and is discarded
under the light of this information.
INSTALLATION
Although
the Venlo greenhouse has a fairly standardized structure, it can be said that
it has a very complex design. This design is preferred because it contains the
maximum area for plant production, which provides minimum loss of incoming
light and at the same time excellent structural strength. Providing structural
strength is not only related to the materials used, but also how the
installation is done. In order to achieve this, special equipment, experience,
precision supervision and workmanship are required and sum of them can be
combined with the highest degree of accuracy. Our supervisor and assembly team
consists of engineers and experienced staff with decades of experience in
building Venlo type greenhouses
GLASSES
There
are different types of coating materials which can be used as greenhouse
coating such as nylon, polycarbonate etc. The surface coating should be decided
by taking into account the long-lasting strength and thus the external factors such
as depreciation expenses, light permeability, insulation capability,
weather-climatic conditions, and resistance to natural disasters such as hail
fail, snow, storm, tornado, fire. To give an example of light permeability, you
should consider that not only how much light will be entered in but also the
range of the transmitted sunlight spectrum. The infrared part of the spectrum
is responsible for generating heat during the day, and depending on the
material type, rate of absorption as well as the warming effect may vary. This
value, combined with the insulation properties at night, will have an impact on
climate management, which will make a big difference in overall operating
costs. Today, glass is still the ideal coating material for Venlo type greenhouses in terms of
reflectance - absorption - transfer values. In particular, when considering
other aspects, the glass prevents all the coating materials.
As Varnet, we use 4.00 mm low iron tempered
glass. Tempering makes the glass 6 times stronger and safer, making it a good
choice for coating the roof. At the same time with excellent thermal insulation
values and a unique sharpness ratio in our glass insulation, UV, heat and
weather resistant provided by EPDM rubber. Glasses of ½ and ¼ size are used on
the first beams, from the shields and partitions to the side walls, to increase
the wind resistance except for the normal size glasses
