High Quality Polycarbonate Greenhouse Glazing
Polycarbonate is the best greenhouse covering due to its performance in extreme climates like wind, hail, snow, wildfires, and extreme temperatures. 5-Wall glazing (16mm thick) is the standard for all our kits because it will perform well in all climates.
Side-by-Side Comparison of Polycarbonate Greenhouse Glazing
Our polycarbonate glazing is 100% recyclable and manufactured in the US. Our kits have been designed to reduce waste by optimizing the dimensions to match the polycarbonate sheets. We have also worked with the manufacturers to reduce extra waste during the fabrication process.

Sealing the Polycarbonate Triangles
The long-lasting Patco aircraft tape is intended to prevent leaks in your Growing Dome. Some small leaks are acceptable, and you may also see drips caused by condensation inside the dome. But if you see a consistent leak, you may want to inspect your tape to make sure it is sealed properly and doesn’t show signs of degradation. In most conditions, the tape will only need to be replaced every 10 years as the UV protection wears off.
Advantages of Polyurethane Tape
- Formulated for resistance to ultraviolet light
- Tough, thermoplastic polyurethane elastomer has a high peel strength and is abrasion, scratch, erosion, tear and puncture resistant.
- Thin and conformable tape is easy to apply and conforms over curved surfaces.
- Acrylic adhesive adheres to a wide variety of substrates and retains a constant level of adhesion over time, yet removes easily when necessary.
- Aerospace-grade polyurethane tape with acrylic adhesive protects the plastic and lumber
