Glazing is the materials that allow sunlight transmission into the greenhouse and represent the greatest decision in selecting greenhouse design. The most used glazing materials are double poly, rigid panels such as acrylic, polycarbonate, and glass.

Double inflated poly comes in many different widths and lengths, working as a direct dealer for major plastic companies in North America we can source custom specifications for your needs.

Polycarbonate comes in many different levels of opacity; this gives you control over your energy for your crop.

At Systems we are also able to bring in custom glass sizes for your greenhouse, and even curved glass depending on the style of greenhouse you are planning to build.

Please talk with our sales representative to get the right greenhouse structure & glazing that’s best for your growing needs.

Some of our customers choose to erect their greenhouses themselves. We supply detailed drawings and instructions for erection, however, we would recommend that you arrange for an experienced greenhouse contractor to install your greenhouse.
