the manufacturer (XL Horticulture),
the following is a copy of the Guarantee Certificate you will receive with
your purchase of polythene.
XL
HORTICULTURE GUARANTEE
TERMS OF GUARANTEE
If there are no reasons as indicated why the film should have failed
XL Horticulture will replace that film within the first year free of charge.
If after the end of the first year and before the end of the fifth year,
the film should fail through faulty manufacture, we will allow 1/60th
off the price of a replacement for every month it falls short of the 5
year period.
The conditions of this guarantee apply only to the UK and Ireland
SPECIAL CONDITIONS
All existing Anti Hot Spot Tape must be replaced or covered with XL Horticulture
Anti Hot Spot Repair / Isolation tape every time the cover is replaced.
All areas where polythene comes into contact with steel work must be covered
with an approved Anti Hot spot Tape containing PE Foam.
Please Note : In conjunction with all other manufacturers this guarantee
is limited to the supply of polythene only. No claims for consequential
loss or labour to re-clad can be entertained.
TO CLAIM
At the first sign of any damage contact the XL Horticulture Distributor
that you purchased the polythene through.
Take photographs / video of the damage.
Produce your Guarantee Certificate to validate the claim.
XL Horticulture or their agents will investigate all claims. This will
usually mean a visit to ascertain the validity of the claim. Occasionally
a chemical analysis may be taken of the film.
XL Horticulture Greenhouse Films are manufactured to the highest standard.
However, it makes no difference how good the film is if there are mechanical
problems relating to the quality of the structure the film is to be used
on, or the way in which the film is fixed. To ensure the validity of your
guarantee please be aware of the potential hazards and solutions.
HAZARDS
a) Rust on metalwork
b) Sharp edges on the joins of multipart hoops
c) Wires, strings etc tied over the hoop - between the
cover and the hoop
d) Sharp edges on ridge pole clamps
e) Over tensioning around localised points - typically
around hoop ends
f) Under tensioning
g) Leaching out of chemicals from wood preservative and
chemical based sprays
h) Too close to heaters
i) Broken down by sunlight
j) Chemical reaction from PVC foam Anti Hot Spot
Tape.
SOLUTIONS
a,b,c and d can all be overcome using
only high quality plastic Anti Hot Spot Tape applied over the top of all
such hazards.
e - Over tensioning can lead to cracking and splitting.
This usually occurs on the side of the tunnel close to the end hoop and
is caused by not evenly tensioning the polythene along the length of the
tunnel. Take care to tension all parts of the polythene evenly.
f - Under tensioning allows the polythene to flap in
high winds. Unfortunately at some point all this flapping is transferred
to a lot of twisting and bending and the wind load is transferred to these
points which is bad for the framework as well as the polythene. If this
happens the polythene will split.
g - Leaching out of chemicals. We suggest that you find
a water based wood preserver low in chlorine.
h - Direct the heat at the plants and not the polythene.
i - Polythene breaks down in sunlight. Polythene manufacturers
incorporate an ingredient that slows down this process. Store all unused
films away from sunlight. Replace all existing Anti Hot Spot tape with
new XL Anti Hot Spot Tape or cover with XL Anti Hot Spot Repair Isolation
Tape.
The above potential hazards affect all polythene and is indicative not
limiting.
USE OF AGROCHEMICALS
Polythene is essentially a hydrocarbon chemical compound and frequent
applications of similar chemicals containing the same elements, which
many agrochemicals do, will be absorbed by the film and will act as a
solvent - de-activating the UV stabiliser and causing the film to degrade
before its design life. The two specific chemicals that have this affect
are sulphur and chlorine. Do not use chemicals that include these elements.
If this is not possible wash the polythene with clean water after contact
with any chemical.
