What Is the Difference Between a Plastic Film and a Traditional Greenhouse?
What Is the Difference Between a Plastic Film and a Traditional Greenhouse? This post will explain the differences between the two and recommend the best option for your greenhouse. You will also learn the distinctions between 6 mil and 8 mil greenhouse films. Finally, the sort of greenhouse you choose will be determined by your budget and the size of your garden. Consider a greenhouse constructed of 6 mm polyethylene to protect your plants from the weather.
Traditional greenhouse
Polyethylene
The installation of polyethylene plastic film is quite simple, however the process differs from greenhouse to greenhouse. Generally, the film is wrapped over the greenhouse frame and attached with little wood strips known as furring strips. Furring strips are commonly used in large greenhouses, whereas a specific channel system may be used in compact greenhouses. A high-quality film may necessitate a unique installation process. Follow the manufacturer’s installation instructions.
While most gardening plastics are manufactured of utility grade polyethylene, polyvinyl is a somewhat more expensive and harder plastic that has a five-year lifespan. It is crucial to remember, however, that it requires care and may need to be changed as needed. Polyethylene plastic film will last at least two to three years with appropriate maintenance. However, it is not as long-lasting as Polyvinyl, a more expensive, tougher plastic that must be cleaned on a regular basis.
PE plastic film can be put double-layered over the greenhouse frame. A double-wall installation will minimize the amount of light transmission by approximately 77%. Although it may appear to be a waste of money, the cost of repairing damaged or yellowed PE sheeting is likely to be cheaper than the cost of a new greenhouse. Regardless matter the purpose of your greenhouse, you’ll be glad you bought the film.
Another option is Sun Selector(tm)/SunTherm 4 greenhouse film. Elife product has 5 layers with two intermediate layers in between. It contains a number of chemicals that help to prevent heat loss and promote air flow. This type of greenhouse film is lightweight and straightforward to install on wood-framed greenhouses. The cost of polyethylene film is determined by its quality, durability, and desired effect.
Polycarbonate is another choice for big greenhouse glazing. This material is flexible and long-lasting, however it is more expensive than polycarbonate. It is frequently multi-layered, with a corrugated sheet sandwiched between two flat sheets. Polyvinyl carbonate is more durable than polycarbonate and is frequently used in commercial greenhouses. The surface of polycarbonate is readily scratched, which is a disadvantage.

Consider which plastic film greenhouse has the best features while selecting one. Rigid plastics endure longer than polyethylene and are easier to install. They are also nearly as clear as glass. They are not flexible, which makes them unsuitable for domed greenhouses. Polycarbonate is also more expensive to install than polyethylene. This is not to say that plastics with deeper layers are less helpful.
Low-density polyethylene is the most cost-effective greenhouse polymer. It can be made into sheets or films as wide as 16 meters. This material is transparent to visible light and active photosynthetic radiation. As a result, the plastic sheet greenhouse will lose energy during the night, requiring heating at night. As a result, a plastic film greenhouse will save money on energy. Here are the advantages and disadvantages of employing a plastic film greenhouse.
Polyethylene is the most often used greenhouse plastic. It is an ideal alternative for greenhouses due to its ease of installation, low cost, and accessibility. It comes in a variety of grades and copolymers. Agricultural-grade polyethylene is more resistant to deterioration than utility-grade polyethylene. However, when it is injured, it might become fragile. The best greenhouse plastics are those classified as agricultural plastic.
Polyvinyl carbonate is your best bet for stiffness and durability. It is more expensive than polycarbonate, but it provides greater protection from the sun, wind, and water. It is also available in several layers, with a corrugated sheet sandwiched between two flat sheets. These plastics are more resistant to puncture and tear and can sustain severe winds. Fortunately, repairs are straightforward.
Polyvinyl carbonate is a strong plastic for greenhouses, but it is much more expensive and comes in shorter lengths. It is also more difficult to deal with, so a longer sheet is recommended. The Elife polycarbonate sheet, on the other hand, is double-layered and measures 48″ by 24″ inches. It can be sliced with a regular Sunnyda knife.

The measuring of the developing structure is the first stage in installing polycarbonate film for a greenhouse. The length of the pipes should then be determined. If the structure has roll-up sides, add four feet to the length of each pipe. Also, ensure that a double layer of plastic is installed from hip board to hip board. Extend the second layer over the entire structure if necessary. Install the rising structure when you’ve chosen the suitable film.
Polycarbonate film for greenhouses comes in two varieties: multiwall and solid. Thermal insulation is improved with multiwall sheets. Light transmission qualities varies between the two types of polycarbonate film. A two-wall polycarbonate sheet permits the greatest light into the greenhouse, but a three-wall polycarbonate sheet restricts light transmission. Another form of polycarbonate film for greenhouses is honeycomb-like polycarbonate.
Glass is another possibility. Polycarbonate’s glass-like qualities makes it an excellent choice for greenhouses because it transmits more light than glass and is 200 times stronger than its competitor, polyethylene. Glass is the most expensive greenhouse building material, while polycarbonate is more expensive than polyethylene. However, the higher cost is justified because it provides superior thermal insulation and improved light transmission. Despite being heavier than glass, polycarbonate is flexible and impact resistant.
Single-wall Polycarbonate is less expensive than glass and easier to deal with. It has an R-value of 0.83, which is less than half that of polycarbonate. Furthermore, polycarbonate yellows over time. It is also easily scratched and worn. Its flutes are also known to attract moisture and pests. As a result, a double-wall polycarbonate greenhouse is healthier for the climate of your greenhouse.
When purchasing polycarbonate sheets, make sure to get one with UV protection. The longer the guarantee period, the higher the quality. Cellular polycarbonate is another option for a more expensive greenhouse film. It weighs about the same as an 8-inch piece of paper. If you opt to purchase cellular polycarbonate, look for a sheet with an additional 10-year warranty. Choose a local polycarbonate supplier for enhanced comfort and convenience. There will be less complications during the installation process. A local provider can readily contact with you and deliver the most competitive quotes.
Polyethylene with two layers
In addition to its numerous advantages, double-layer polyethylene plastic film is less expensive than its competitors. While UVA Clear and UVB film are both good insulators, growers prefer polyethylene because of its superior thermic characteristics. Polyethylene, in addition to being less expensive than alternatives, provides improved ventilation through the greenhouse. However, it is not the best answer for every scenario.
Aside from the advantages described above, double-layer polyethylene plastic film is lightweight and simple to install. For added strength and longevity, this style of greenhouse covering is also available with heavy-duty framing. It comes with a ventilation package and a heating system. In addition to being lightweight, this sort of greenhouse covering is made in the United States and comes with all of the attachments required to assure the plants’ comfort.
The installation of polyethylene plastic film differs depending on the type of greenhouse. Most greenhouses attach it by hanging it over the frame. Furring strips are small wood strips used to secure the film to the frame. To secure a more expensive kind of polyethylene plastic film to the structure, a particular channel system is required. It can cost up to $10,000 depending on the quality of the film.
Greenhouse plastic film is less expensive than glass sheets. The material’s clear, long-lasting characteristics allow for excellent light diffusion while also protecting against UV rays. Plastic sheets will lower energy bills and lessen the need for artificial warmth. Aside from lowering energy costs, plastic films boost plant yield, allowing you to grow more and profit more. Because of these advantages, double-layer polyethylene greenhouse plastic film is an excellent choice for your greenhouse.
Polyethylene is the most prevalent type of plastic used in greenhouses. This film is often sold in rolls. It’s lightweight and easy to cut to fit your greenhouse structure. Polyethylene film comes in a variety of grades, ranging from one-year to four-year. UV-resistant polyethylene films reflect heat back into the greenhouse. The reflective plastic film uses less electricity.
