South West Growers Show committee member and XL managing director Les Lane said the first results from trials in Thessaly, Greece, confirmed predictions that SunMaster SuperThermic could trap solar radiation, reducing the need for overnight heating.
The technology is based on a new additive to the polythene that selectively filters the long- and short-wave radiation, allowing XL to manufacture extremely thin covers that retain heat for longer.
The independent trial is being conducted by the University of Reading's Dr Demetrius Ducas and reported its initial findings at the most recent International Plant Propagators' Society meeting. The initial findings, based on the first 15 months of data, will be followed up next year with a full report.
SunMaster SuperThermic was awarded "best professional equipment" at Four Oaks Trade Show.
