Terms of Warranty If there are no reasons as indicated overleaf why the film should have failed within the first 12 months XL Horticulture Ltd. will supply another sheet completely free of charge. If after the end of 12 months 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 new XLpoly replacement film for every month that it falls short of the five year warranty period. The conditions of this warranty apply only in the U.K. And Eire. Special Conditions All existing Anti Hot Spot Tape must be replaced or covered with XL Horticulture Anti Hot Spot / Isolation Tape every time the cover is replaced. All areas where polythene comes into contact with steelwork must be covered with an approved Anti Hot Spot Tape manufactured from PE (not PVC) foam. PLEASE NOTE As is common within the industry this warranty is limited to the supply of polythene only. No claims for consequential loss or reimbursement for labour to re-clad the structure can be entertained.
TO CLAIM At the first sign of any damage contact the XL Horticulture Distributor that you purchased the polythene through. Take photos/video of any damage. Digital images are good because they can be emailed. PRODUCE THIS WARRANTY CERTIFICATE TO VALIDATE THE CLAIM.
XL Horticulture Ltd. Or their agents will investigate all claims. This will sometimes 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 that the film is to be used on, or the way in which the film is fixed. To ensure the validity of your warranty please be aware of and comply with the potential hazards and solutions. HAZARDS A. Rust on metalwork B. Sharp edges on the joins of multi part hoops C. Wires strings etc tied onto the hoop, between the cover and the hoop. D. Sharp edges on ridge tube clamps E. Over tensioning around localised points - typically around tunnel ends. F. Under tensioning around localised points - typically around tunnel ends. G. Leaching out of chemicals from wood preservatives and chemical based sprays. H. Too close to heaters. I. Broken down by sunlight J. Chemical reaction from PVC foam based Anti Hot Spot Tapes. The above potential hazards affect all polythene covers and the list is indicative, not limiting.
SOLUTIONS A.BC. And D. Can all be overcome using only high quality PE foam based Anti Hot Spot Tape (as supplied by XL Horticulture) over the top of such hazards. E. Under 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 under tensioning the polythene along the length of the tunnel. Take care to tension the polythene evenly. F. Under tensioning allows the polythene to flap in the wind. 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 which is low in Chlorine. H. Direct the heat at the plants and not the polythene.
SPECIAL NOTE:- USE OF AGROCHEMICALS. Polythene is essentially a hydrocarbon compound and frequent applications of similar chemicals containing the same elements, which many chemical sprays do, will be absorbed by the film and act as a solvent, de-activating the UV stabiliser and causing the film to de-grade before the end of its design life. The two specific chemicals that have this affect are Sulphur and Chlorine. Try not to use chemicals that include these elements. If this is not possible wash the polythene clean, with water, after contact with any chemical |
