OLS Screens

Greenhouse solution that cools by day and stays warm at night


Gintec’s OLS screens are used to protect all greenhouse grown crops. These 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:

  1. In cover roll installations immediately beneath the ventilators in the greenhouse. The open structure of the fabric allows good ventilation.
  2. 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.
  3. 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 is to provide maximum cooling by day during the summer and countering heat radiation on cold nights.

Use of OLS roll screens limit crop damage through spring and night frosts as well as hot summer days.

Gintec’s 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’). Length can be cut to specification. Wider widths may be obtained by cutting and/or sewing combinations together using Gintec’s sewing techniques.
