Looveren NV supplies of horticultural glass with the highest light transmission (10/09/2008)

In October 2008 by Van Looveren NV first greenhouse glass with anti-reflective (AR) coating in Belgium. Producer of the AR coating on the glass GroGlass from Riga (Latvia). The greenhouse, with an area of 2 hectares and a glass size of 2160 x 1663mm, is being built by Havecon BV Netherlands. Greenhouse growers is tomato grower Dirk Verlinden from Our Lady-Waver. At Van Looveren NV is expected that the greenhouse roof material of the future as it meets all modern production requirements and responding to current production problems. Meanwhile state at Van Looveren NV also half Dutch project in the pipeline for 0.5 ha greenhouse builder BV Van Amelsvoort and strawberry grower to Prinsenbeek Franken. Size 2108 x 1495mm glass there.

8% growth light

Traditional 4mm horticultural glass has a light transmission of about 89% up to approximately 91% measured according to the Dutch standard NEN2675. The BS 2675 provides a measurement perpendicular to the glass. According to a new method developed by TNO is only about 82%. This method takes into account a realistic greenhouse light angles between 40 ° and 70 ° in the growth light spectrum between 400 nanometers and 700nanometer.

GroGlass ™ AR-glass is basically the same glass, only one has both sides a thin coating that the intrinsic reflection in the glass virtually eliminates light transmission so that the relative increase of 8%, measured by this new method.

High durability

GroGlass ™ AR-glass on the greenhouse roof exposed to extreme conditions and the coating was this extensive and intensive testing. The GroGlass ™ AR-coating is resistant to the influence of UV light, acid rain, continuous condensation on the inside and outside of the glass, salt deposits, sand storms and extreme temperature changes. GroGlass ™ AR-glass has successfully test using the European standard EN 1096-2 passed. Standard EN 1096-2 defines the durability requirements for coated glass to outside circumstances blootgesteld.Meer yield per square meter but equal cost

The heat transfer is the same as for ordinary 4mm horticultural glass. The expected yield is more integral per square meter while the heating blijven.Meer same light but less heat in the greenhouse

The coating is light for growth but simultaneously reduces the radiation in the infrared part (above 780 nanometers). This provides an average 5% less warming in the applicable kas.Gemakkelijk

Unlike previous products GroGlass ™ AR-glass, which is not easy to apply additional requirements kasconstructies states. Any existing greenhouse with 4mm glass can also be herdekt GroGlass ™ AR-glass. GroGlass ™ AR-glass is cut and processed as normal horticultural glass.
