Coverings

The Wire Lock system is popular for the following applications:
*Single layer of poly 4 mil, or 6 mil or larger
*Double layer poly 4 mil, or 6 mil or larger
*Roll-up sidewalls
*Seasonal application of shade material over the greenhouse

This lock system consists of an aluminum base and preformed stainless steel wire insert that holds the poly securely in place. It also comes in a shape for gable ends (fits on top of the last bow on each end of the greenhouse). The double can be used in conjunction with a roll-up side wall. The strong point of this lock is that it secures a variety of material thicknesses.

Traditional AC systems are based on additives that are incorporated in the mass of the film and function by migrating to its surface. As time passes these additives are depleted leaving the film without any anti-condensate function that could prevent the formation of droplets. It is known that after a new AC film is installed, crop quality, earliness and yield are better in the 1st and 2nd year. This is because the gradual absence of AC after the second year causes the accumulation of droplets on the film and reduces light transmission.
The SunMaster film line will now use revolutionary anti-condensate technology called the “Surface Treatment System (STS) allowing the feature to last the entire life-time of the film. By extending the life of the AC feature, the grower can reduce the possibility of disease caused by wet leaves and make it possible to reduce the use of chemicals thus lowering production costs.
The Sun Master EVO AC, will be available in the following widths:
12', 14', 16', 18', 20', 21', 22', 24', 28', 32', 36', 40', 42' & 44'

Hi-Core XL is a rigid, multi-wall, translucent sheet, made from a tough polyolefin alloy that is protected from UV and weather by an Environmental Protection System that is exclusive to Matra Plast. Light passing through Hi-Core XL is highly diffused, (over 95%). Diffused light is bent to many different angles. Compared to nondiffusing materials, Hi-Core XL allows the light to make a service building brighter or to penetrate deeper into the leaf canopy to impact with more crop. For more information, contact your nearest Griffin office.
