U.V.
stabilized Insect Screens from Green.tek, correctly installed prevent
insect penetration, yet provide maximum possible air flow that is
essential for optimal crop yields.
All greenhouse openings including intake vents, service doors, etc.,
should be screened for best results, and double screened doors should
be installed.

Caution: Any screening retrofitted flush
to a greenhouse's vents without other changes will decrease airflow and
increase greenhouse temperatures. Contact Green-Tek to help you make
the proper fit!
The following procedure should help avoid serious
ventilation problems. An additional consideration: if you start with
pests already inside or bring pests in on plants or clothing, screening
will keep them inside.
