Which Is The Best Choice For Greenhouse Panels?


Looking for the best material to cover your greenhouse? With the variety of different options available in the market, you might be very confused as to which one is the best. If you are looking for an answer to the above question, you must first understand that a greenhouse must be able to transmit light, withstand extreme weather conditions and retain heat. So, you need a material that will help in bringing in maximum amount of sunlight and letting the least amount of heat to escape. It must also be strong enough to withstand all kinds of extreme temperatures and climate.

While considering the material for your greenhouse, you must consider its installation, budget and maintenance too. Materials for greenhouse panels include glass, fiberglass, polycarbonate, acrylic and many more. Every material has its own advantages and disadvantages. Read below to learn about the pros and cons of each one so that you can choose the most durable, easy to maintain and the one that suits your requirements the most.


Glass has been the traditional greenhouse covering material since the beginning of time. It is also the most popular because it can transmit light the best. Glass is also the most aesthetically pleasing materials. If constructed well, glass can last for around 30 years or so. However, there are many drawbacks of using glass in a greenhouse. Firstly, it is very expensive to install and frame because it is very heavy and fragile. Also, the metal framing does not insulate well thus, lots of heat is lost easily. During the daytime, a glass greenhouse becomes too hot if not ventilated properly, which can be harmful to the plants inside. Moreover, if the glass breaks, it becomes difficult and expensive to replace it.


Acrylic greenhouse coverings are very popular among people because it is a very strong and durable material that can withstand snow, hail and strong winds. However, acrylic is very expensive. But, considering that it can last for 20 long years, it can be said to be cost-effective in the long run. Acrylic panels are flexible enough to be moulded over shallow arcs but, there are specific attachments required with acrylic panels due to expansion and contraction caused by weather conditions.


Polycarbonate is another strong yet lightweight material. It does not let in as much sunlight as glass does but, it diffuses the light which creates an optimum environment for the growing plants inside. It has excellent heat retention and insulation properties. It is obviously not as pleasing to the eyes as glass but, it is very easy to maintain and is budget-friendly. A polycarbonate roof can last for years together without breaking or any need of heavy framing. Nowadays, UV treatments are available for polycarbonate greenhouse panels to help preventing fading and yellowing with a guarantee of about 10 years. If you are planning to opt for polycarbonate, you must approach Tuflite Polymers, who has been providing the best-in-class solid and textured polycarbonate sheets and multiwall polycarbonate sheets to a number of greenhouses across the globe.


Fiberglass is stronger than glass and can withstand extreme climates better. It also lets in the same amount of sunlight as glass does. The best thing about fiberglass is that it is one of the least expensive options, and is easy to install and replace. But, overtime fiberglass becomes yellow and thus, gets difficult to clean. This makes fiberglass panels less attractive, not letting in much sunlight; thus making it necessary to replace the panels. Another issue with fiberglass is that it is highly flammable.
