Hoklartherm | Retractable Roller Shade Cloth Curtains for Greenhouses 8ft long in 6 widths, White Aluminized

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 curtains fit many makes and models of greenhouse. 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. The wall roller blind 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 6'6" - rolls should not be used in applications longer than 6'6". The fabric length is 8 feet, however several wraps of fabric remaining on the roll are necessary to maintain tension on the fabric attachment point. 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 roof units will hang down from the ridge beam and consist of 2 rolls each: one going left the other right. The wall units are sold as individual rolls.

Each roll is 8 feet (6'6" usable length) of white acrylic shade cloth with aluminum weave, available in 6 widths.

Note: For Janssens Victorian greenhouses - a standard glass section is 29.5" wide. So the 59" & 88" sets work the best, depending on your portal frames, spandrels, and window spacing plan.

Please carefully review this introduction, sizing, and FAQ document as well, which will help you determine what to order for the right fit.

Note: For the Janssens Modern greenhouses, we have these shade cloth curtains in an extra-long size for those models, please see this page.

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!
