Greenhouse plastic is the type of plastic used to build a greenhouse. It is usually thicker than regular plastic and bends easily. This kind of plastic is often used to build the particular room for the plants.
Since there are more than one type of this plastic, you need to know each of them to make sure that you can choose which one is suitable for your greenhouse.
The most common type of the plastic is called polyethylene plastic. It can be found easily in any builder stores around your area.
This kind of plastic is usually produced in different thickness and strength level. The thicker one is for larger industrial applications. For home and personal use, you can use the thinner one.
Polyethylene plastic is great for greenhouse material because it has great durability. The plastic can last for over a year with good maintenance.
If you want ever stronger plastic than the polyethylene, you can go with this copolymer one. This type of plastic is not only stronger but also even more durable.
The plastic can last for over three years on your greenhouse. It resists against extreme weather quite well and will not break easily, even under these circumstances:
- Heavy rain
- Extreme heat from the sun
- Heavy snow
- Strong wind
This type of plastic is often named as the best kind of personal-grade greenhouse plastic to imitate glass effect, hence perfect for the greenhouse. Unfortunately, copolymer is quite expensive.
Polyethylene and copolymer plastics are usually used to build smaller greenhouse. However, if you plan to build a huge one, you need to buy industrial grade plastic. This polyvinyl plastic is the example.
Polyvinyl is obviously way stronger than the other two plastics mentioned earlier. The strength of the plastic is so great that even adults cannot snap them with ease. This is why a larger greenhouse will have stronger walls and structures if the owner covers it with polyvinyl.
With good care, polyvinyl does not have to get replaced for over five years. If the cleaning and inspection are done frequently, the plastic can even last for 7 years.
If you think polyvinyl is the strongest of all plastics, you are wrong because you have not get introduced to polycarbonate plastic. This kind of plastic is the king of industrial grade plastic for greenhouse.
The plastic has great thickness and strength. It is believed that the strength of this plastic is twice of those of polyethylene plastic.
For larger greenhouse, replacing the plastic every couple of years is quite bothering. However, with the usage of polycarbonate, you do not even have to replace the plastic for a decade. Yes, it lasts for 10 years and more, with proper maintenance, of course.
Those are the types of greenhouse plastic that are widely used around the world. If you want to build a smaller greenhouse, use the first two types. However, if you plan to build a larger one, the later types suit your need better.
