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 roller 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 clothes are optimized for Janssens Victorian, Junior Victorian, Modern, and Gigant greenhouses, and may also fit many other makes and models of greenhouse, such as Hoklartherm, KGT, Janssens, Vego, and others.
A spring tensioned roller is mounted in the housing with the shade cloth ready to be pulled out using the included pull cord. The roller shade housing is fastened at eave height (for wall shades) or on the roof ridge (for roof shades) using brackets and screws, hanging chains, etc. The wall roller shade can be pulled out and attached to the floor profile of the greenhouse using the screw hooks supplied.
Note: The available pull out length of the shade cloth fabric is less than the full amount of cloth on the roll - rolls should not be used in applications longer than the indicated maximum pull-out length. The fabric length is longer, however several wraps of fabric must remain on the roll to maintain tension on the fabric attachment point and avoid the risk of detaching the cloth from the roller.
Shading value is 55-60%
See this YouTube video for an introduction to the shade clothes.
These are available for both the roof and for side walls. The double roll roof units will hang down from the ridge beam and consist of 2 rolls each: one going left the other right. The sidewall and pent roof units are sold as individual single rolls.
Each roll has a certain usable pullout / extension length of shade cloth fabric. There are 6 available widths, with various pull out lengths.
Note: For Janssens Victorian, Junior Victorian, Modern, and Gigant greenhouses - each standard glass section is 29.5" wide. So the 59"- & 88"-wide sets work well, depending on your portal frames, spandrels, window placement, and shelving plan.
Please carefully review this introduction, sizing, and FAQ document, which will help you determine what to order for the right fit for Janssens Victorian, Junior Victorian, Modern, and Gigant greenhouses.
The special Hoklartherm shading fabric is a white acrylic 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. Importantly, 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!
