Gintec's OLS Screens
Gintec's OLS screens are used to protect all greenhouse grown crops.
Gintec's OLS screens are specially designed for use in fixed or roller screen
installations intended for interior or external applications of both glass and
plastic houses.
The open structure of the fabric allows adequate air replacement between the
two sides. The aluminum strips used reflect the strong sunlight so that the
greenhouse stays cool by day. At the same time, the roller screen reduces heat
radiation at night, resulting in a higher inside temperature.
OLS screens can be applied in the following three ways.
-
In cover roll installations immediately beneath the ventilators in the
greenhouse. The open structure of the fabric allows good ventilation.
-
Against the glass on the outside of the greenhouse or at some distance from
it. Solar rays are reflected outside the house with this method. This
produces the largest possible temperature reduction. This method also
offers protection against hail.
-
Close to the sheeting on the outside of plastic Quonsets. A simple manually
operated system is available for rolling the screen up and down. The main
objectives of this method are: maximum cooling by day during the summer and
countering heat radiation on cold nights.
Use of OLS roll screens therefore limits crop damage through spring and night
frosts as well as hot summer days.
OLS screens are manufactured in 30%, 40%, 50%, 60%, 70%, and 80% shade factors.
An OLS 90% ABRI is also available. ABRI refers to a 2.3mm polyester support
wire knitted into the screen. Standard width is 4.2 meters (13.77'). Lengths
can be cut to specification. Wider widths may be obtained by cutting and/or
sewing combinations together using Gintec Shade Technologies sewing techniques.
