The Solexx Paneling,

Solexx Paneling comes in a continuous roll that is 49.5 inches (4 feet, 1.5 inches) wide by up to 1,000 feet long, so it's easy to apply vertically or horizontally onto your structure. Overlap the panels or use the custom H-Channel connectors where the panels meet. Customers can order the precise length of paneling they need, virtually eliminating any waste.

You can replace your old poly with the new Solexx Paneling, running the rolled twin-walled material up and over the entire greenhouse structure or running it the length of the greenhouse. Or use it for end walls and side walls.
