Greenhouse is one of the most important high technology facility that greatly contributes to growing plants. This is also known as glasshouse. This is purposely designed to provide sufficient heating to regulate the temperature conditions of the plants’ environment especially when the external temperature drops down due to cold weather. This is technically created using transparent materials which traps heat inside. This makes the interior of the house warmer to keep the climatic plants live and grow.
How does it work? As we all know that when the light coming from the sun passes through the glass roof or walls of the greenhouse, its heat, infrared radiation and the present carbon dioxide is trapped by the glass and could not escape the premise. This causes the internal temperature to rise, the trapped heat is then absorbed by the earth which is utilised by the plants.
To date, commercial glass greenhouses are made available to people and the agricultural industry. This is to improve or increase the production of flowers and vegetables that needs regulated climatic conditions. Because of the advent of technology, greenhouse facilities could be controlled using a computer. This computer will control the greenhouse’s cooling, lighting and heating mechanism. Using this is definitely an optimum way to maximise plant production.
Since the glass plays a key role in covering the greenhouse, it is also good for you to know the different types of glass so that you will have an idea which is the best cut to size greenhouse glass to be used for walls and roofs. Below are main types of the greenhouse glass:
- Tempered glass
This is the most popular type of glass used in a greenhouse. It has the capacity to regulate fluctuating temperatures inside the facility. It is best recommended to use this type on the walls and doors. It may also be used for roofs however, it is not the best option when there is heavy snow deposits or when the wind is high. Compared to the other types, this is much stronger as far as the structure is concerned. The tempered glass could easily be distinguished because the glass is very clear compared to the others.
- Laminated glass
Try to study your car’s wind shield, this is definitely made up of laminated glass. This type of greenhouse glass is composed of layers where two or more glass sheets are bonded together. These glasses which are formed to layers are held together using a polyvinyl butyral. If the tempered glass breaks and could pose risks to the people nearby, this laminated glass does not break into pieces.
- Annealed glass
This is the cheapest greenhouse glass you can purchase in the market nowadays. So, if you are in a tight budget, this works best for you! If you are using a controlled greenhouse structure, the annealed glass is the best option for the greenhouse. This has the ability to be heat treaded. Plus, this glass makes it easier to relax the internal stress inside the house. However, it could never be denied that this plain glass has the highest probability of breaking.
