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.\u003c\/p\u003e\n\u003cp\u003eThese Hoklartherm shade clothes are optimized \u003cstrong\u003efor \u003cmeta charset=\"utf-8\"\u003eJanssens Victorian, Junior Victorian, Modern, and Gigant greenhouses\u003c\/strong\u003e, and may also fit many other makes and models of greenhouse, such as Hoklartherm, KGT, Janssens, Vego, and others.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eNote: The \u003cstrong\u003eavailable pull out length of the shade cloth fabric is less than the full amount of cloth on the roll\u003c\/strong\u003e - 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.\u003c\/p\u003e\n\u003cp\u003eShading value is 55-60%\u003c\/p\u003e\n\u003cp\u003eSee this YouTube video for an introduction to the shade clothes.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe class=\"responsive-video\" src=\"https:\/\/www.youtube.com\/embed\/X6sdlLSjYto?si=P5_42r6ETbGo0n4l\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eThese are available for both the roof and for side walls.

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.\u003c\/p\u003e\n\u003cp\u003eShading 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.\u003c\/p\u003e\n\u003cp\u003eAll 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!\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eIf you need a different width or pullout length, please contact us at 888-648-5333 or via email at info@mygreenhousestore.com.
