Hints for installation and care taking of greenhouse film
Guidelines for receiving greenhouse film and issues with shipments:
All rolls are well packed and thoroughly prepared for shipping, with special focus to the front
sides which are secured with extra protection. Although we do recommend inspecting received
goods in detail to avoid any hidden or disputable claims.
1. First check shipment to be complete and for any missing items or obviouss damages
especially folds on the front sides of the roll.
2. In case of any visible damages or any doubts please mark shipping documents clearly
while forwarder is still present. This is very important to secure your rights and avoid
discussions later on.
3. Take pictures of visible damages or doubtful marks whenever possible.
4. Contact or any of its representatives immediately in such cases and have invoice no,
delivery note or shipping docs on hand. This way we can work to resolve potential
issues quickly.
Installing film on greenhouses or tunnels:
1. Before installing any greenhouse film please check construction carefully for any sharp
edges or outstanding construction parts and cover such with adequate material (we do
recommend foam tape!)
2. Avoid extreme weather conditions when installing (e.g. heavy wind or rain, snow, frost).
A perfect outside temperature is between 10 and 20 ° Celsius
3. Check all equipment used for installation, e.g. unwinding machine for any sharp edges
and tape those if necessary with foam tape.
4. Please keep a distance with unwinding equipment of > 10 m from first tunnel arches and
try to unwind in same height as ridge of tunnel (see sketch page 1). To avoid damages
caused by heavy tension you should unwind film first on a distance of app. 10 m prior
unfolding. Heavy tension can cause cuts in the fold and claims caused by this will be
rejected. c. general instructions:
General instructions:
1. Please pay attention when using material to fix/tension the film e.g. rope, belt or metal
clips. Your warranty will be revoked, if film does get damaged caused by non adequate
items (e.g. nails, screws, wooden parts).
2. We do recommend checking tension of rope or belt on a regular base on greenhouse
tunnels. Please adjust if necessary. Wrong tension can cause damages through flapping
(too low tension) or crack (tension too high). Greenhouse film is temperature sensitive
therefore pay special attention during/after change of seasons.
3. You should store greenhouse film cool , dry and in darkness.
4. If you lift film on tunnel sides for ventilation manually please check wind film towards
“inside” the tunnel (reduction of water deposits) and check tension of ropes or belt to
avoid scratching or high pressure.
5. Using double film for greenhouse: please start air blower on lower pressure, increasing
slowly to give film time to stretch. We always recommend using air blower with
pressure control.
6. Areas, where the film touches parts of the construction (i.e. steel tubes, ridge pole), should
be covered with protection film.
7. After heavy rain or snowfall check film for water or snow deposits, if necessary remove
water or snow deposits carefully.
8. Use of chemicals i.e. like sulfur and chlorine is reducing lifetime of film. Any use
can be traced afterwards and will lead in revoking warranty of film.
W
hen calculating your needs in greenhouse film please be aware there is a certain
coefficient of linear expansion due to temperatures, means in very low temperatures
there might be a few linear meters less, in very high temperatures a few linear meters
more than at the moment of rewinding on the rolls. Therefore we recommend to order
a few linear meters
in addition to be on the safe side.
ATTENTION:
in strong wind / extreme weather conditions (if the film is insufficient fixed)
your greenhouse tunnels may fly away. This could create extremely dangerous situations,
for instance closed by high voltage power lines.
