Description

Shade cloth curtains are an optimal solution for greenhouses.  Especially in greenhouses with garden glass or ISO safety glass, shading is absolutely necessary to prevent "burning" on your plants from too much direct sunlight.  These nice high quality self-retracting/roll-up white aluminized shade cloth curtains filter out excess sunlight, reducing heat on hot summer days. Lower inside temperatures help protect your special plants and create a cooler environment for your entertaining. 

These Hoklartherm shade curtains fit the 10 ft deep Janssens Modern greenhouses, Models M34-Modern and M36-Modern.  A roller blind is mounted in the housing/shade ready to be pulled out. The roller blind housing is fastened at eave height (for wall shades) or on the roof ridge (for roof shades) using brackets and screws, hanging chains, etc. Both the roof and wall roller blind can be pulled out 10 ft and attached to the corresponding frame profile of the greenhouse using the screw hooks supplied. 

The Roof and Wall curtains are both single-roll units.  Each roll is 10 feet of shade cloth with aluminum weave, in 59" width.  You will need 3 for the M34 and 3 for the M36.  The situation with the M36 is a little problematic though due to the large heavy angle braces that come down from the ceiling on this large model, and which are usually place just left and right of the center. This means 2 panes in the center for which the Modern 59” works and then 3 panes to either side which we would recommend using the Modern 59” as well but – it will not give complete coverage.  Only the Modern 59” will work for the Modern roof as it is the only one with a long enough roll of fabric for the roof.  Please look at the pictures to see more details.

The special Hoklartherm shading fabric is a white polyester weave with a high aluminum content, making it highly reflective. Solar radiation is reflected by the fabric and thus not converted into heat (reflection principle, roughly corresponds to that of a mirror - no heat is generated on a mirror; in contrast, a black background gets really hot). The opinion is often expressed that interior shading is not effective and that exterior shading is therefore preferable. This is only partially true, the right shading material - light/white with a large amount of silver, moisture-resistant, UV-stable, dirt-repellent - is crucial. 

Shading should be installed before the plants in the greenhouse have grown too large . The sun can heat up your greenhouse quite a bit. If the temperatures rise too high, the plants practically curl up. This is how they try to brave the heat. However, this severely limits plant growth. A bad harvest or even a complete crop failure is imminent. Interior shading can help here. Although the interior shading still lets the sunlight through the greenhouse panes, it gives the plants enough shade and thus lowers the greenhouse interior temperature. Important, the heat must escape through appropriate ventilation options - greenhouse windows, doors, exhaust fans.

All large production greenhouses have automatic interior shading with this type of shading fabric! Advantage: The shading is not exposed to the weather (wind and rain). This helps create a pleasant and growth-friendly climate in the greenhouse . Build and trust in our many years of experience!
