What are the Pros and Cons of 8mm Twin Wall Polycarbonate Panels for Greenhouses?

When it comes to greenhouse coverings, 8mm twin wall polycarbonate panels offer a range of benefits and potential drawbacks. These panels are becoming increasingly popular due to their durability, light transmission, and insulating properties. Let’s explore the pros and cons of using 8mm twin wall polycarbonate panels for your greenhouse.

Pros of 8mm Twin Wall Polycarbonate Panels

High Light Transmission: 8mm twin wall polycarbonate panels offer a high degree of light transmittance, allowing up to 81% of photosynthetically active radiation (PAR) to pass through. This is crucial for plant growth and development.
Unbreakable and Shatterproof: Polycarbonate is 10 times stronger than acrylic and 200 times stronger than glass. These panels are virtually unbreakable, making them resistant to impacts, hail, and other weather extremes.
Thermal Stability: Polycarbonate panels can withstand temperatures ranging from -40°C to 105°C (-40°F to 221°F). This thermal stability helps maintain a more consistent greenhouse temperature, keeping it cooler in the summer and warmer in the winter.
Easy to Cut and Install: 8mm twin wall polycarbonate panels are relatively easy to cut and install. They can be cut with a hobby knife or circular saw, making it simple to fit them into your greenhouse structure.
Versatile Usage: These panels are suitable for a wide range of applications beyond greenhouses, such as pool roofs, aisle roofs, garden fences, outdoor canopies, and house decorations.

Cons of 8mm Twin Wall Polycarbonate Panels

Higher Initial Cost: Compared to some other greenhouse covering options, 8mm twin wall polycarbonate panels may have a higher upfront cost. However, their durability and long-term performance may offset this expense over time.
Potential Condensation: The twin-wall structure of these panels can sometimes lead to condensation buildup. This condensation can drip onto plants and potentially cause issues if not properly managed.
Requires Proper Sealing: To prevent dirt, dust, and insects from entering the channels between the walls, 8mm twin wall polycarbonate panels must be properly sealed at the top and bottom. This sealing process adds an extra step during installation.
Potential Discoloration: Over time, prolonged exposure to UV radiation can cause the panels to discolor or become less transparent. Using UV-resistant coatings or additives can help mitigate this issue.
