polycarbonate sheet suppliersOver the past several years, polycarbonate has grown immensely in popularity, often serving as a replacement for glass and other plastic composites for various applications. Polycarbonate multiwall sheets for greenhouses are especially making a big impression on the commercial and residential gardening industries. Greenhouse polycarbonate sheets come in a variety of configurations. Choosing the right polycarbonate panels for your specific purposes is important to guarantee that you’re reaping the maximum benefits from your structure. Here are some of the most important factors to consider when purchasing polycarbonate greenhouse panels in Canada.


Structure and Thickness

Greenhouses rely on efficient and consistent thermal insulation as well as temperature regulation to ensure the health and longevity of the plants inside. Depending on the climate in your area, it may be necessary to construct a greenhouse structure with thick or thin walls to allow for proper airflow and humidity levels. Polycarbonate greenhouse replacement panels come in a variety of sizes and thicknesses to accommodate your temperature and humidity requirements.

Light Transmission and Diffusion

Each plant species need a certain amount of light exposure throughout the day. Multiwall polycarbonate sheets are about 90% more effective at transmitting and diffusing light evenly throughout your structure than glass.

Strong Weather Resistance

Weather resistance is another important consideration when it comes to choosing multiwall sheets for greenhouses. Seasonal climate, weather, and temperature fluctuations can greatly impact the growth patterns and health of your greenhouse plants. For that reason, you should be careful when selecting the right thickness for your structure. Polycarbonate is generally extremely thick and can withstand all kinds of inclement weather conditions such as snow, heavy winds, and even hail. Thinner panels are ideal for mild weather conditions and temperatures, but a thicker composition may be required for more intense climates.

Single-Wall Polycarbonate

Single-wall polycarbonate is appropriate for warm climates or if you’re planning on heating your greenhouse during the winter months. This will help regulate the temperatures and prevent the interior of your structure from overheating.

Twin-Wall Polycarbonate

Twin-wall polycarbonate sheets consist of one honeycomb or zigzag layer sandwiched between two solid panels for added durability. These multiwall sheets offer superior UV ray-filtering as well as light emission and diffusion properties that allow your greenhouse plants to flourish without burning their leaves. They also offer superior insulation, making them the more energy-efficient option.

Triple-Wall Polycarbonate

Triple-wall polycarbonate sheets are the best option for cold climates that require an extra layer of protection for greenhouse plants. Consisting of three layers, they offer the ultimate temperature regulation, insulation, and heat retention to prevent frost damage in plants. These qualities make triple-wall polycarbonate greenhouse panels the most effective at withstanding frigid Canadian winters.
