      FAQs About Covering a Greenhouse

      What is the best material for covering a greenhouse?

      The best material depends on your climate and structure, with polycarbonate offering the most durability while polyethylene film serves as a cost-effective seasonal option. Choosing a greenhouse cover like shade cloth is also essential for protecting crops from intense summer heat.

      How do you install a greenhouse cover?

      To install a greenhouse cover, pull the material taut over the frame and secure it using specialized fasteners like spring locks for film or H-profiles for rigid panels. Ensure all sharp edges on the frame are covered with felt tape to prevent the new covering from tearing or wearing prematurely.

      Can I install a new greenhouse cover over an old one?

      It is best to remove old materials to inspect the frame for damage, though you can double-layer film if using an inflation fan to create an insulating air gap. Replacing an old greenhouse cover entirely ensures the best light transmission and structural integrity.

      What hardware is needed for covering a greenhouse with polycarbonate?

      Installation requires H-profiles for joining panels, U-profiles for sealing edges, and screws equipped with EPDM washers. These specific fasteners allow for thermal expansion while maintaining a waterproof seal on your greenhouse cover.
