6. Can I automate the windows?
Yes, we supply an Automatic Window Opener for roof vents which are activated by temperature changes. As heat builds up above the desired temperature, the arm activates, opening the window. As the temperature cools, the window closes. It works on a thermally powered piston, so there are no batteries or motors to fail. Clear instructions come with the unit. Adjustable between 15 and 25 degrees C. Do not heat greenhouse to more than 50 degrees C.
7. Do I require shadenet?
Due to high temperatures in Southern Africa, it is recommended to put the greenhouse in an area where it will get shade from the sun during the hottest part of the day – somewhere between 10am and 3pm depending on where you are in SA. If you don’t have a shady area, you will probably need shadenetting. We provide a high quality metallized, knitted, reflective screen (60%), made of a mixture of aluminium and polyethylene, with UV resistant (5 year guarantee) and anti-oxidation coating for durability and longevity, enables moderation of day/night temperatures (36% energy conservation), provides uniform shadow (62%) and optimal diffused light (55%), prevents irradiation damage and reduces the heat in the greenhouse during hot days, efficient energy conservation in winter.
8. Are the Polycarbonate panels hail proof?
The polycarbonate panels ARE hail-proof; no damage from local hail storms (tested since Apr 05). Parts are easily replaced if damaged. The polycarbonate does not discolour or crack. Polycarbonates are a particular group of thermoplastics with an incredibly high resistance to impact. As such, these plastics are very widely used in modern manufacturing (a major component of bullet-proof glass). It's ability to handle high temperatures sees it used in microwave cookware. The life expectancy can be as much as 30 years. It is reported to be 50 times stronger than acrylic. The polycarbonate walls used for the greenhouses are twin walled – 4mm thick or 6mm thick. |
9. Is there a guarantee?
The units carry a 7 year manufacturer’s warranty for any manufacturing defect, however the product has life expectancy of 15+ years. The Rion manufacturing plant is ISO9002 certified in Quality Management, Health & Safety & Environmental Management. See manufacturer’s web site www.rion.com.
