What are Greenhouse Polycarbonate Panels?

Polycarbonate panels are a type of plastic building material known for their durability and shatterproof qualities. These panels are also UV protected, easy to clean, and lightweight, making them an ideal choice for greenhouse construction.

Benefits Of Polycarbonate Panels:

They are very popular for a reason – because they are really good! Here are the benefits you can expect from using greenhouse polycarbonate panels.

Durability:Polycarbonate panels are incredibly durable and resistant to impact. Unlike glass, they’re less likely to break or shatter when hit by debris, making them a safer option. They can withstand extreme weather conditions, including high winds and heavy snow, ensuring long-lasting performance.
Light Diffusion:Polycarbonate panels have excellent light diffusion properties. They can spread light evenly throughout the greenhouse, which helps to promote uniform plant growth. This feature reduces the incidence of plants being burned by direct sunlight, a common issue in glass greenhouses.
Insulation:These panels provide better insulation than glass, helping to keep the greenhouse warmer in winter and cooler in summer. This is due to their multi-wall structure, which traps air in between layers, reducing heat transfer. As a result, gardeners may find they spend less on heating and cooling the greenhouse.
Lightweight:Polycarbonate panels are much lighter than glass, making them easier to transport and install. This can lead to lower shipping and labor costs. Their lightweight nature also means that the greenhouse structure doesn’t need to be as heavily built to support the weight of the covering, potentially reducing construction costs.
UV Protection:Many polycarbonate panels come with a UV protective layer that shields plants from harmful ultraviolet rays while allowing beneficial sunlight to pass through. This protection helps prevent plant damage and extends the life of the panels by reducing UV degradation.
Flexibility:Polycarbonate is a flexible material that can be easily cut and shaped, allowing for a variety of greenhouse designs, including curved or irregular shapes that would be difficult or expensive to achieve with glass.

Types of Polycarbonate Panels for Greenhouses

Corrugated single layer panels and clear multiwall panels are the two main types of polycarbonate panels used for greenhouse construction. Each type has its own unique features and benefits that cater to different greenhouse needs.

Corrugated single layer panels

Corrugated single layer panels offer a budget-friendly and lightweight option for greenhouse construction. Their unique ridged design provides strength and stability while allowing natural light to penetrate the structure, creating an optimal environment for plant growth.

These panels are easy to install and maintain, making them an ideal choice for horticultural structures.

The durable nature of corrugated single layer panels also ensures long-term use in various weather conditions. With UV protection and resistance to impact, these panels provide a sustainable and eco-friendly option for greenhouse roofing.

Clear multiwall panels

Clear multiwall panels are a popular choice for greenhouse construction due to their exceptional light transmission and thermal insulation properties. These panels consist of multiple walls or layers that create pockets of air, providing excellent insulation while allowing natural light to penetrate the structure.

The use of clear multiwall panels also ensures durability and resistance to impact, making them suitable for withstanding harsh weather conditions. With their lightweight nature and ease of installation, these panels offer a practical solution for creating energy-efficient and sustainable greenhouse structures.

The transparency and strength of clear multiwall panels make them an ideal choice for horticultural structures where maintaining optimal growing conditions is essential. These versatile panels provide UV protection, ensuring that plants receive adequate sunlight without being exposed to harmful radiation.
