Insulated Solexx 49 x 99 Greenhouse Panels reduce your heating costs while providing 70-77 percent soft, diffused light – which is the best light for plants. The Solexx Greenhouse Panels are 49.5 in. x 99 in. and have strong, shatter-proof greenhouse glazing protects your plants from strong winds, snow, and other harsh weather conditions and unlike other twin-wall greenhouse coverings, the flexible paneling can be bent around corners and easily cut with a utility knife. The Solexx 49 x 99 Greenhouse Panels are now available in panels up to 12 ft. long and rolls up to 1000 ft. long, making it easy to re-cover just about any structure.

Light is important for your plants, but glass greenhouse panels let in intense direct light which create hot spots and will burn your plants. Polycarbonate greenhouse coverings are an improvement but still only partially diffuse the light, leaving your plants vulnerable to sunburn. But with the diffused-light of the polyethylene your plants will not suffer sunburn and as a result they will be healthier and grow more vigorously. In addition, the twin-wall structure provides insulating value from both heat and cold. Many hobbyist greenhouses are classified as season extenders and are not designed for year-round growing. For cold conditions select a greenhouse with the thickest panels and also use a gas or electric heating system.

Solexx 49 x 99 Greenhouse Panels Features:

  • Panel size: 49.5 in. x 99 in.
  • Choice of panel number
  • Choice of thickness 3.5 mm or 5 mm
  • Hardware available as an option

Note for hardware: Once you design your greenhouse and calculate how many panels you need, you will also need several different types of hardware to connect the panels and create waterproof joints. These are very economical pieces that will make your greenhouse complete.  Click to view needed hardware.
