Hoklartherm | Retractable Shade Cloth Curtains for Janssens Modern Greenhouses, White Aluminized HOK-MODERN-SHADE - HOK-MODERN-SHADE

  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. 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. 

Features

• 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 4 for the M36.
• The special Hoklartherm shading fabric is white 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.

Maintenance Tips

• Clean the Glass or Polycarbonate Panels Regularly: Use a soft cloth with mild soap and water to keep panels free of dirt, algae, and debris. Avoid abrasive cleaners that may scratch the surface.

• Inspect and Tighten Frame Components: Periodically check the aluminum or steel frame for loose bolts, screws, or connectors. Tighten them to maintain structural integrity.

• Lubricate Moving Parts: Apply silicone spray or a light lubricant to door hinges, window openers, and vents to ensure smooth operation and prevent rust.

• Check Weather Seals and Gaskets: Examine seals around doors and windows for wear or gaps. Replace if damaged to maintain insulation and prevent moisture intrusion.

• Maintain Proper Drainage: Clear gutters and downspouts of leaves and debris to ensure proper water flow and prevent overflow or leaks.

• Ventilate to Prevent Condensation: Use roof vents and doors to regulate humidity inside the greenhouse, especially during cold months, to reduce mold and mildew growth.

• Protect in Severe Weather: In case of heavy snow or wind, consider reinforcing panels and removing snow accumulation from the roof to avoid excessive weight or pressure
