Transmission of light
For greenhouses, light transmission from a four-millimeter polycarbonate panel is enough. These panels are more robust, provide better thermal insulation, and weigh less than equivalent twin wall choices. Polycarbonate panels can also be used to construct carports, skylights, and pergolas. Polycarbonate, unlike glass, permits 62 percent light transmission when transparent, with the exception of bronze layered and opal panels.
When putting up polycarbonate greenhouse panels, keep in mind that they are not scratch resistant. They are also easily dented or scuffed and must be cleaned on a regular basis. If you choose twin-wall polycarbonate panels, you should wipe them down on a regular basis to prevent dirt from gathering. This may result in less light transmission. It is also critical that the panels are correctly capped with foil tape and U channel.
Choosing the best polycarbonate panel for your greenhouse necessitates serious thought. Clear sheets are good for greenhouses, although different species may require varying levels of light. In general, light transmission of 80 to 90 percent is considered adequate, while certain crops may have different needs. Depending on your climate, a two-wall, triple-wall, or honeycomb polycarbonate panel may be appropriate. A thick panel will impede light transmission, whereas a thin panel is ideal for greenhouses. Light transmission is also affected by the hue of the polycarbonate.
If you are concerned about thermal insulation, a twin-wall polycarbonate panel is advised. It has the potential to lessen the requirement for heating and cooling. Twin-wall polycarbonate is perfect for greenhouses because it enables up to 85 percent of light to pass through. This is a good choice for individuals who do not want to sacrifice light transmission. Polycarbonate panels are classified into three types: triple-wall, twin-wall, and double-wall. Each of these kinds has benefits and drawbacks.
Durability
If you’re thinking about purchasing a polycarbonate greenhouse panel, seek for a reputable manufacturer with high quality requirements. The panel should be strong and long-lasting, so choose one with specifications and a long history of good quality and service. Be wary of low-cost panels – the Far East is known for producing low-cost polycarbonate greenhouse panels, many of which come from shady vendors. Because they were cut with imprecise cutting knives and worn out machines, these panels may not be as sturdy as they could be. Purchasing a greenhouse panel from an unidentified provider may result in a deformed edge since the manufacturer may apply pressure to the panels in order to make them thinner.
The amount of light that may pass through a polycarbonate greenhouse panel is determined by its thickness. A single-wall panel provides the highest light transmission, with around 90% to 95% of light passing through. Twin-wall polycarbonate greenhouse panels, on the other hand, combine two layers of polycarbonate to provide superior insulation and durability than a single-wall panel. In general, a twin-wall panel reduces light transmission by around 10%, which is sufficient for greenhouses.
UV protection should be considered while designing a polycarbonate greenhouse panel. Polycarbonate is a material capable of absorbing up to 70% of the sun’s radiation. A panel with a UV protection of 72% will prevent the light from directly affecting plants. This means that even without a robust greenhouse construction, plants will be shielded from sunburn. Furthermore, polycarbonate panels are impact and shatter resistant, and their color will not fade over time. They also reduce heat loss and do not fade with time. They also provide UV protection, which is great for a greenhouse panel. Plants will still receive the sunshine they require to grow healthy and vigorous, despite the durability of polycarbonate panels.

Cost
A greenhouse can be built with a single sheet of 4mm polycarbonate or an 8mm double-walled construction. Gardeners prefer the former due to its proclivity to distort, but the latter is utilized for sheds and cover canopies. Your greenhouse panel’s thickness impacts its radius of curvature, panel structure, and minimum distance between supports. Keep the following points in mind while shopping for a greenhouse panel:
You should also be familiar with the installation procedure. Glass panes are easily replaceable, however Polycarbonate sheets must be obtained from a manufacturer. Furthermore, glass must be cleaned on a regular basis. If you’re not sure how to install the panels, refer to Elife installation guide, which covers building codes and installation instructions. You should also look at the warranty terms provided by the manufacturer.
A 4mm polycarbonate panel is more expensive than glass, but it performs better and requires less care. A high-quality panel will survive for years, whereas a low-cost panel would need to be replaced on a regular basis. In the end, the superior material will save you money. When it comes to greenhouses, polycarbonate is the greatest option. A high-quality panel can last for decades, ensuring that your greenhouse’s functioning and looks remain as good as when it was new.
A greenhouse’s panel should be transparent in order for light to pass through. The standard color for greenhouse panels is clear polycarbonate. The addition of a color increases the light transmission rate by 15% to 30%. A comparison of clear, opal, and bronze 2-wall, 4mm polycarbonate panels is provided in the table below. Choosing a panel based on color reduces the panel’s overall cost.
Colors are available
4mm polycarbonate panels in a variety of colors are available for greenhouses. While clear greenhouse panels are the most frequent, they can also be used in a variety of hues. The amount of light transmitted by the panel is determined by the color you choose. The table below compares transparent, opal, and bronze 2-wall panels. Choose the color that best complements the appearance of your greenhouse.
Choose a dark-colored polycarbonate panel if you’re growing vegetables or berries. Polycarbonate transmits light at a high rate of up to 72 percent. You’ll require a darker-colored panel for mushrooms and berries. A dark polycarbonate panel will be more useful if you use low-cost power for lighting and heating.
Polycarbonate panels with more than one layer provide a higher R-value in cold areas. More insulation means a thicker sheet. The greater the R-value, the greater the benefit. If you do not intend to heat your greenhouse, however, the greatest R-value is not required. If you reside in an area where nighttime temperatures can fall below zero, you can choose a darker panel for the same reasons.
The color of the panels in a greenhouse will influence how much light your plants receive. The panel color can block some light rays, giving you more control over the quantity of heat and light entering your greenhouse. Although green is the most efficient hue for shutting off some light, it can also be a great choice for mature plants. The covering color will aid in the uniform distribution of light throughout the greenhouse, resulting in fewer shadows and more efficient photosynthesis.
Environmental consequences
Polycarbonate is an ideal material for greenhouse construction since it transmits light up to 72 percent. Polycarbonate panels are so great for producing berries and mushrooms. Furthermore, they require less heating and lighting, making them an excellent alternative for anyone looking to reduce the environmental effect of their greenhouse. However, there are several disadvantages to using polycarbonate. Here are some of the advantages of polycarbonate over glass.
Polycarbonate sheets can be monolithic or cellular in nature. A cellular sheet is comparable to a sandwich in that the stiffening walls are perpendicularly aligned. Polycarbonate sheet is the chosen material for glazing greenhouse walls and roofs due to its superior temperature and energy resistance. To protect it from dangerous UV radiation, it must be exposed to the sun’s ultraviolet rays before installation.
The panels are available in a variety of colors. The most common hue is clear polycarbonate, but opal is also available for greenhouse applications. Because of its great impact strength, it will keep the greenhouse cool while preventing accidental hits and vandalism. A polycarbonate sheet is also long-lasting and weather-resistant, making it an excellent choice for greenhouses. Finally, a polycarbonate sheet is a versatile material.
Polycarbonate panels are extremely robust and flexible, in addition to being environmentally friendly. The panels distribute heat evenly and inhibit microbial growth. Furthermore, they provide UV protection, which aids in maintaining a steady environment in the greenhouse. Regardless matter the purpose of your greenhouse, a polycarbonate panel will save you money in the long term.
